3.2 FUNCTION TESTS
The following function tests can be performed to confirm the conditions described in Table 1. Use Figure 1.4
(page 4) to locate test points.
• TEST LIGHTS: Short the “Test Lights” test points and check that all panel lights turn “ON” and that the
audible alarm turns on. If the “active “ relay test is used the Carbon Monoxide, Combustible and Vent relays
will activate during this test.
• FUNCTION TEST: Apply gas from a cigarette lighter (without flame) or other high concentration source to
the Methane sensor and check that the Combustible Alarm light goes on.
• FAILED SENSOR TESTS: When the respective failed sensor test pins are shorted together a failure of the
selected sensor will be simulated. During this test the sensor failure LED indicator will glow and the Fail and
Remote relays will activate.
