7.1.3 ABORT ZONE TEST
Press the "ACK" key at any time to abort the ZONE TEST function.
-
Zone circuits under test are returned to normal.
7.1.4 NOTES
(a)
An Alarm detected on the zone under test when one is not expected (eg during the
FAULT test) is processed normally and the test aborted. Similarly, faults during the
ALARM test activate the fault sounder and may terminate the test.
(b)
During the zone test sequence any other zones to which the tested circuits are
mapped behave as they normally would given FAULT and ALARM conditions.
(c)
All alarm processing delays (AVF sequences, etc) are still active so the alarm
response time may be up to 60 seconds, depending on the circuit type.
(d)
An AVF delay sequence initiated by a zone alarm test continues if the zone test is
aborted by the "ACK" key before the test has passed. That is, an alarm re-test of the
same zone within 120 sec will give an instant alarm.
(e)
The test condition is automatically removed from the circuits after 120 seconds.
(f)
Alarms or faults on any circuits zones other than those under test will abort the test
and remove all test signals. The alarm or fault is then treated normally.
(h)
On Flow Switch Zones the test relay will operate for 2 minutes. If no alarm is
received within that time, the test will fail.
(i)
It is not possible to start a zone test if there is an un-acknowledged alarm or fault
present; or if there is an Auto, System, Battery, Zone or Auto-Reset Test in progress.
Also, Flow Switch Zones cannot be tested if they do not have any relay programmed for
alarm testing.
7.1.5 OPERATING SEQUENCE (NETWORKED ZONE)
OPTION:
To prevent mapped outputs from operating "ISOLATE" the zone first.
From the zone status recall display for the zone to be tested, press:
