Using the Self-Test Feature
The self-test feature on this detector provides a convenient way to test the major functions of
the complete system. This feature can only be activated after the unit has completed its warm-
up phase. Activate the self-test by pressing the “SELF TEST” button for approximately one
second.
The self-test performs the following events in sequence:
1. Tests each display digit by displaying “0” through “9”
2. Activates the Zone 1 Low Alert relay and indicator LED for 30 seconds
3. Waits for 30 seconds
4. Activates the Zone 1 High Alert relay and indicator LED for 30 seconds
5. Waits for 30 seconds
6. Activates the Zone 1 Alarm relay and indicator LED for 30 seconds
7. Waits for 30 seconds
8. Activates the Zone 2 Low Alert relay and indicator LED for 30 seconds
9. Waits for 30 seconds
10.Activates the Zone 2 High Alert relay and indicator LED for 30 seconds
11. Waits for 30 seconds
12.Activates the Zone 2 Alarm relay and indicator LED for 30 seconds
13.Waits for 30 seconds
14.Activates the internal alarm for 3 seconds
15.Resumes normal operation
Before using the self-test feature, we recommend testing the ventilation system wiring for
correct connections and operating the ventilation components manually. Make any wiring
changes and replace any defective components. Any problems found during the self-test can
then be identified much easier. Although the self-test feature tests much of the detector’s
functions, it does not test the sensors’ response to the target gas. Page 30 gives hints and
procedures for testing the sensors’ response.
