2.  Insert the two screws provided and secure the mounting 

plate to the wall or ceiling surface. (If mounting in 
plasterboard or drywall, drill a 3/16 in. hole and use the 
plastic anchors provided.) 

3.  After the mounting plate is secured, slide the alarm over the 

mounting plate (see Figure 4 on page 2). 

Two labels have been provided that have important information 
on what to do in case of an alarm. Add the phone number of your 
emergency service provider in the space provided. Place one label 
next to the alarm after it is mounted, and one label near a fresh air 
source such as a door or window. 

The following section provides a general guideline for 
programming (learning) the unit into control panel memory. Refer 
to the panel documentation for complete programming details. 

1.  Set the panel to program mode. 

2.  Proceed to the Learn/Add Sensors menu. 

3.  Select the desired sensor number. 

4.  Trip the wall tamper by removing the alarm body from the 

mounting plate. 

5.  When the panel prompts you for sensor group number, enter 

the appropriate group number based on the system panel. 

6.  At the panel, exit program mode. 

7.  Place the alarm body back onto the mounting plate. 

This unit is sealed. The cover is not removable. 

The control panel must be placed into sensor test 

mode while conducting any tests. Placing the control panel into 
sensor test mode for all testing helps to protect against false 
alarms and unintentional central station reporting. 

Due to the loudness of the alarm, we suggest that you place your 
fingers over the sounder vent while testing your alarm. 

Continuous exposure to the high sound level of this 

alarm over an extended period of time may cause hearing loss. 

The CO alarm provides three test modes: 

• 

Normal CO alarm test. Conducts an internal self test and 
tests the sounder. 

• 

RF communication test. Tests the communication path with 
the control panel. 

• 

CO alarm functional gas test. Tests the functional operation 
of the CO sensing element. 

1.  Wait at least 10 minutes after installation to test the CO 

alarm. 

2.  Make sure the green Power LED is flashing for normal 

operation. 

3.  Set the control panel to sensor test mode. 

4.  Press and hold the Test/Hush button until the unit beeps once 

(approximately 1 second), and then release the button. If the 
unit is operating properly, you will hear four quick beeps, 
followed by 5 seconds of silence, followed by four quick 
beeps. 

5.  At the control panel, exit sensor test mode. 

Note: This test mode does not test communication with the 
control panel. You will receive a “Sensor Test Fail or Abort” 
message when the control panel exits sensor test mode. 

This section provides general guidelines for testing the CO alarm 
with the panel. Refer to the specific panel documentation for 
complete testing details. 

Before testing, ensure that your control panel is set to sensor test 
mode. Setting your panel to sensor test mode prevents an alarm 
signal from being transmitted to the central monitoring station (if 
you have a monitored system). 

1.  Wait at least 10 minutes after installation to test the CO 

alarm. 

2.  Make sure the green Power LED is flashing for normal 

operation. 

3.  Set the control panel to sensor test mode. 

4.  Press and hold the Test/Hush button until the unit beeps two 

times (approximately 5 seconds), and then release the button. 
If the unit is operating properly, you will hear four quick 
beeps. The unit will send the RF test packets after the first 
four beeps. 

5.  The control panel will beep and display the number of RF 

packets received. 

6.  At the panel, exit sensor test mode. 

Consult the most recent version of NFPA 720 for more 

information regarding the requirement for functional testing of CO 
alarms and/or your Local Authority Having Jurisdiction (AHJ).
