ZONE ALARM OR FAULT TEST
7.1.1 FUNCTION
To test the circuit inputs of a selected alarm zone and send test alarm signals to the Brigade.
Two tests can be performed:
(a)
A true fault simulation test, or
(b)
A true alarm simulation test.
WARNING:
This test performs a true zone test, time delays operate, and all outputs
operate, including MASTER ALARM OUTPUT, unless the zone is isolated.
Testing a Local Zone is covered in Section 7.1.2 and a Remote Networked Zone is covered
in Section 7.1.5.
7.1.2 OPERATING SEQUENCE (LOCAL ZONE)
OPTION
:
To prevent mapped outputs from operating "ISOLATE" the zone first.
Refer to "Zone Isolate or De-Isolating" section.
From the zone status recall display for the zone to be tested, press:
OR
From other information displays or the base display, press:
OR
where n n n is the number of the zone to test.
-
The relevant test signal is applied to all circuits on the zone.
-
Once all the circuits have gone into the test state, the relevant zone indicator
and fault sounder are turned on, if that zone is not isolated. FFCIF mode may
be entered if the zone being alarm tested is mapped to the MAF.
The LCD displays a test pass message, and pressing the "ACK" key clears
the test.
-
If any circuit does not enter the correct state in response to the test signal,
then the test fails, the relevant zone indicator stays OFF and the buzzer
sounds its "TEST FAIL" cadence. The LCD displays a test fail message, and
pressing the "ACK" key clears the test.
