Wall Box (D) : Each area monitor mounts to its o wn ChemDAQ wall box. The wall box contains the power supply which converts the line - in AC power to DC. Although the wall box comes with its own AC power cord, you have the option of hard - wiring it into your electrical system. For systems using remote sen sor modules or remote displays, the wall box contains the terminal blocks for connecting the signal cables . The wall box is designed to be mounted to the surface of the wall and should NOT be recessed. ( See mounting instructions on p.19 ) Remote Display (E): This unit does NOT detect gas. Rather, it duplicates the readout and alarm indications from its parent gas monitor. Often remote displays are mounted next to doorways, allowing you to see the ppm levels inside the next room without having to enter a potentially hazardous area. A signal cable (included with your shipment) connects the remote display to the gas monitor. The cable carries data as well as the 15VDC supplied by the monitor . The label on the front of the unit will identify it as a remote display, helping you distinguish it from the area monitor.

If your ChemDAQ system has more than one remote display con nected to a single area monitor, decide which cabling configuration works best. (See bel ow.) Y ou can - daisy chain multiple remote displays to the gas monitor. Or each remote display can have its own cable run ba ck to the gas monitor (star configuration). Or you can combine star and daisy - chain. Each area gas monitor can support a MAXIMUM of THREE remote displays, regardless of cable configuration. (In instances where more than three remote displays per gas monitor are required, the additional remote displays need supplemental power. Talk to your ChemDAQ technician for additional information. ) Daisy chain Star Area Monitor Area Monitor Area Monitor Combination daisy chain, Star Remote Display Cable

Orient the wall box so the strain relief nut (A) for the power cord is on the BOTTOM. b. Verify the w all box configuration matches the monitor type. Wall boxes for standard monitors (B) have only one strain relief nut (A), for the power cord. Wall boxes for remote sensor monitors (C) require TWO strain relief nuts (D), one for the p ower cord and one for the remote sensor cable. 4. M ount the wall box using wall anchors and #6 (3.5mm dia.) screws, or fasten it to electrical box. Be careful not to damage components on the circuit board.

Mount the Remote Sensor If your system does not include a remote sensor unit, you may skip this step. 1. If the sensor will sit on a free - standing sterilizer as shown (A) , simply attach using the enc losed Velcro strips. Typically ChemDAQ technicians will place the sensor mount flush to the front edge of the sterilizer . Note: For hydrogen peroxide sterilizers, it’s possible to see brief readings of 5ppm or higher when the door is opened after a load is run, resulting in the gas monitor alarming. If this happens, try adjusting the low alarm to 7.0 or 10ppm. See page 38 . Safety Note: Workers should avoid reaching into the sterilizer until ppm readings drop BELOW 1.0ppm. 2. For wall - mounting, use the 2 keyhole slots (B) in the back of the remote sensor mount. Be sure to review the sensor - placement guidelines on page 11 .

Decide Where You Will Place the Remote Displays If your system does not include a remote display, you m ay skip this section. Before mounting the displays, refer to the instructions on page 25 . 1. The remote display duplicates the readout and alarm indications from its parent gas monitor. It does not detect gas. Typically it is mounted by a door which lead s into an area where a gas monitor is located. (See A.) 2. Mount t he remote display high enough to be readily visible , while also keeping it safe from collision with swinging doors, carts , and other traffic. 3. The button on the di splay silences the alarm horn , so consider mounting it within arm’s reach (C) . The button silences ONLY the remote display. It does not silence the parent gas monitor, nor does it silence other remote displays. 4. The remote display receives its 15VDC power f rom its parent gas monitor through a signal cable (see A) so it’s NOT necessary to mount it near an electrical outlet. 5. You will mount the display using flathead screws (provided by customer.) Note the k eyhole slots on the back (B). Because the unit is lig htweight, two diagonal screws will suffice . Option : In locations where installing mounting screws is impractical, industrial grade Velcro strips are sufficient to hold it in place. 6. The remote display cable will feed through a grommet on the top edge of t he rem ote display. (Note the cable in picture A .) Option : If you prefer to keep the signal cable hidden from sight, mount the display over an electrical box and route the cable through t he grommet in the access door (C ) . (Note: The unit will be mounted i n the same manner as described i n step 5 above.)

Avoiding Cross - Sensitivity Issues When choosing a location for your area monitors / sensors, avoid locations prone to causing cross - sensitivity issues. Review the information below. Sensor Type Possible Cross - Sensitivity Issues Ethylene Oxide (ETO) ChemDAQ’s Spot - On ® Filter technology mak es our ETO sensors the most reliable electro chemical sensor on the market, eliminating almost all cross - sensitivity issues in a typical sterile processing department. However, placing the sensor in a location where interferent chemicals are persistent c an compromise the filter, leading to false readings. In instances where your facility’s ventilation system is pulling fumes from the outside, installing inexpensive charcoal filters in the air handler has proven very effective. 1. Heavy use of Isopropyl Alc ohol : Routine use of IPA (i.e. what is typical in most sterile processing departments ) does not pose a problem; however, you should AVOID placing the sensor ... In l ocations where heavy alcohol washes / wipe - downs are performed. Near Medivators or other wash ers using alcohol. Adjacent to alcohol - based hand sanitizer dispensers . 2. Other fumes which can cause cross sensitivity issues : Engine exhaust (idling trucks, mowers, helicopters etc.) Exhaust from propane engines such as forklifts. S ewer fumes from floor d rains.

CM - 113 - A - 0.00 ChemDAQ ® Customer - Install Guide, Steri - Trac ® Gas Mo nitoring System - 5 Components shipped with your system: Main Components Take a moment to be come familiar with the ChemDAQ system components . Note: Not all components shown are necessarily included in your particular system. Sensor Module (A) : The sensor module contains the electrochemical sensor which detects the target gas. The circuitry in the module converts the analog signal to a digital ppm (parts per million) reading and sends the data to the area monitor for display . The colored ring on the sensor module identifies which gas - type the sensor module is designed to detect. Area Monitor (B & C) : The area monitor displays the ppm data received from the sensor module. It also has an alarm horn which sound s when the detected gas levels reach the alarm point. The button on the front silences the alarm and also serves as a menu access button for configuring the area monitor. Area monitors come in two configurations. On the standard configuration (B) , the sensor module connects directly to the body of the area monitor. On the remote sensor configuration (C) , the sensor is connected to a remot e sensor mount . The sensor module sends data to the area m onitor over a signal cable. This allows the user to place the sensor in a location where it would be impractical to Orange : Ethylene Oxide Blue : Hydrogen Peroxide Brown : Peracetic Acid ( Not all ring colors and gas t ypes are listed . ) Ring color indicates target gas.

Activating the Area Monitors 1. Verify the following work has been done: Wall boxes wired and area monitors mounted. Remote Sensor Units wired . Remote Displays wired and mounted. 2. Apply ele ctrical power to the area monitors. (Plug in the AC power cord or close switch/ circuit breaker.) 3. Verify: The monitor display should illuminate, cycle through some test screens, and then flash ‘NO SNSR ’ (“No Sensor”). NOTE: If the monitors do not perform as described above, STOP, turn off power, check wiring in wall box, or call your ChemDAQ technician. 13. Installing Sensors. If your system contains sensors of multiple gas - types , make sure the colored ri ng on the sensor module matches the color of the gas - type printed on the label of the area monitor. (A) Note: When handling the sensors, please avoid touching the electrical connector which mates with the area monitor. 1. To install a sensor to the area mon itor , squeeze the retaining clip (B) and slide onto monitor. The sensor should be oriented as shown in (A). 2. For remote sensor units, simply slide the sensor onto the mount as shown. (C) 3. When the sensor is connected, verify: The status LED (D) illuminates green. The monitor display s ‘READ’ and then show the (non - adjusted) PPM reading. ( If the monitor displays READ for more than 30 seconds, remove sensor and then connect again. ) It is normal for the sensor to read something other than 0.0ppm when first i nstalled.

Electrical: Decide how you will supply 110 (to 220) VAC power to the wall box of each area monitor. 1. Each ChemDAQ wall box requires 110 (to 220) VAC power . Choose one of two options: The ChemDAQ wall box comes with an AC power cord already installed and can simply be plugged into an existing AC outlet. The cord is 48 inches (122 cm) long. Or you can remove the power cord and hardwire the wall box directly into your electrical circuit . See hardwiring requirements below. 2. REQUIREMENTS FOR HARDW IRING : a. W ire: 14 AWG (1.6mm dia.) SJ or SJO . (Larger diameter wire will not fit into the connectors in the wall box .) b. The ground wire must be earth - grounded. c. You must install a mechanism for turning off power to the area monitor. You can either install a switch in series with the monitor OR you can connect the area monitor to its own circuit breaker (15 Amp or higher). The circuit breaker must be within a reasonable distance to the monitors. Plug - In vs. Hard - Wiring Advantages to plugging the monitor into an electrical outlet: Existing outlets can be used, el iminating the need for running additional electrical wiring. Ease of maintenance: The monitor can be powered down simply by unplugging the cord . Advantages to hard - wiring the monitor: Cleaner looking install: No visible power cords. Monitors ar e more tamper resistant, reducing the chance of unauthorized personnel unplugging the monitor.
36. CM - 113 - A - 0.00 ChemDAQ ® Customer - Install Guide, Steri - Trac ® Gas Mo nitoring System - 36 Menu button Oxygen Sen sors: For oxygen (O 2 ) sensors, the “zero - adjust” procedure does not set the baseline to 0.0ppm, but rather to 20.9%, the level of oxygen in normal atmosphere. The procedure for establishing the baseline is the same as the zero - adjust procedure except tha t in step C, the menu option will be CAIR (calibrate air) rather than ZERO. 14. Zero - Adjusting the Sensor. 1. A newly installed sensor needs to be acclimated to its new environment. The zero - adjust func tion sets the sensor’s baseline to zero to account for ambient variations. (Exception: For Oxygen sensors, the zero - adjust procedure actually sets reading to 20.9%, the level of oxygen in normal atmosphere. See side bar. ) 2. P erforming the Zero - Adjust Function: Recommendation: Read the instructions through completely before attempting. Note: If you make a mistake during the procedure , just release the button. After several seconds the monitor will return to its main display. Then try again. a) Press and hold the menu button on the monitor until you see MENU on the main display. Then release the button. b) Press and hold the button until you see ZERO displayed (or CAIR for oxygen sensor) then release the button . c) With ZERO (or CAIR) displayed, press the button once and release . Important!! You should perform the zero - adjust function even if the sensor is reading 0.0ppm (or 20.9% for oxygen sensor). Perform the z ero - adjust function only when no target gas is present . Do not perform the zero adjust, for example, while sterilizers are in operation. After a sensor has been installed, wait at least five minutes before performing the zero - adjust. This allows time for the sensor to settle. (If the s ensor has been off - power for more than a week wait ten minutes before performing the zero - adjust.)
9. CM - 113 - A - 0.00 ChemDAQ ® Customer - Install Guide, Steri - Trac ® Gas Mo nitoring System - 9 60 inches / 150cm What is the detection range of the sensor? The sensor can only detect what is right in front of it; that is, the target gas must diffuse through the membrane of the elect rochemical sensor to register a response. The sensor cannot detect at ‘long range.’ If there is a leak of the target gas in the area, the speed of the sensor’s response depends on how quickly the gas spreads and reaches the sensor. In order to achi eve a fast response time, ChemDAQ recommends placing the monitor as close to the gas source as practical but no more than five feet (1.5 meters) away. Floor Standard Area Monitor A B 1A. Decide Where You Will Mount The ChemDAQ Wall Box (F or the Standard Area Mo nitor ) If your system does not include a standard area monitor, you may skip this section and proceed to p. 11 1. Standard area monitor s have the sensor (A) connected to the body of the monitor as shown. 2. Locate the area monitor as close to the target - gas source as practical . This ensures a fast response time if there is a leak. See sidebar on detection range. 3. If possible m ount the area monitor about 60 inches (150cm) from the floor. This places the sensor in the breathing zone (no se level) , critical for employee safety. (See Figure B right.) 4. Make sure the monitor is located in a ‘safe’ area where it is not prone to collision with doors, carts , or other traffic . If needed, consider installing a protec tive cage around the monitor or a door/cart stop. 5. Do not place the monitor in locations prone to rapid heat or humidity swings. ChemDAQ recommends the area monitor be placed no closer than t en feet (3 meters) to the door or rear area of a steam sterilizer. (See temperature and other p erformance specifications on Steri - Trac Gas Monitor User Manual. ) 6. Do not place the monitor in a location where it is prone to get wet. 7. For ethylene oxide (ETO ) monitors, it’s important to place the units a safe distance from chemical/fume sources that might cause cross - sensitivity issues. See table on page 12 .

To activate a remote security panel in the event of an a larm. To signal exhaust fans to run at a higher speed in the event of an alarm. To close doors to hazardous areas in the event of an alarm. 5. Decide: Will you use the dry relay contacts at the area monitor to interface with an external device? This step is optional and applies only to customers who choose to use the d ry contacts at the area monitor to interface with an external device. See the right sidebar for sample applications . 1. The dry contacts are inside the ChemDAQ wall box. (Terminal block J3 ) 2. The contacts provide no electrical power; they simply serve as ‘sw itches’ that activate when the area monitor goes into alarm. 3. There are two sets of contacts: One for the low level alarm and one for the high level alarm. (Both alarm settings are user - adjustable.) Each set provides a normally open and a normally closed terminal. 4. The dry contacts are rated for 1 amp at 120 - 220 VAC, or 1 amp for 30VDC for any load, resistive or inductive. 5. The relay contacts are energized into their ‘normal position,’ so if the monitor loses power, the relays respond in the same manner a s if the monitor were in alarm. a. Normally Open: Contacts are open during normal conditions; closed in alarm condition ( or if monitor loses power). b. Normally Closed: Contacts are closed during normal conditions. Open in alarm condit ion (or if monitor loses power). 6. The customer will provide the signal cable for this application.

43. CM - 113 - A - 0.00 ChemDAQ ® Customer - Install Guide, Steri - Trac ® Gas Mo nitoring System - 43 Sensor Installation Troubleshooting (continued) Problem Possible Diagnosis Try the Following: Error Code 0003 Over - range. Sensor is reading high, be yond maximum range. **IMPORTANT** Don’t overlook the possibility that the high readings are caused by presence of the target gas. Investigate. If unsure, install sensor only when you are confident no target gas is present. If the sensor has been o ff - electrical power (i.e. not connected to a powered gas monitor) for more than two weeks, the sensor might have lost its electrical charge and needs time to stabilize. Let the sensor charge overnight on the gas monitor to see if the readings come down. Pe rform the zero - adjust on the sensor only after the readings have stabilized. If this does not resolve the problem, contact ChemDAQ technical services. Gas monitor is alarming at a very low ppm level (e.g. below 1.0ppm) During zero - adjust procedure, user may have accidentally lowered low - alarm setting. Remove sensor. Refer to page 38 to raise alarm back to default level. Reinstall sensor. Attempt zero - adjust procedure again , p. 36 . Cannot enter ME NU on gas monitor. Monitor is alarming. (User is locked out of menu during alarm situation.) If monitor is in alarm, you will not be able to enter the menu. If the ppm level is low (below 1.0ppm) and is alarming , remove sensor and refer to step above “G as monitor is alarming at a very low ppm level...” Monitor flashes RED Z0.0 after performing zero - adjust procedure. PPM readings on area monitor are too high. The monitor will not let you zero out a sensor if the readings are 2.0ppm or above. Give the sens or an extra hour to settle before zero - adjusting. If this does not resolve the problem, contact ChemDAQ technical services.
