The system may be electrically tested by pressing the test pad located on the control unit for 15 seconds, after which the pre-alarm state will be initiated with the exception of the relay, by maintaining pressure on the test pad for a further 15 seconds a full alarm condition will result including the operation of both relays.
Each sensor has an individual test switch which when pressed simulates gas present and turns the green LEDto red and switches the sounder on.
To ensure that the system responds correctly to the presence of gas, each sensor should be exposed to test gas. It is advisable to carry out this test at least every six months. -
During test periods alarm relays may be inhibited by pressing the reset pad for four seconds after which the fault indicator will illuminate and maintain all relays in the normal non-alarm state. F F
