System Testing
For general testing, DIP switches 3 and 4 (Alarm delays) should be disabled. This is to prevent a 1
to 5-minute delay before alarms are raised (see
section 4.1
).
Connect a
dry sensor
to the unit to prevent inadvertently triggering the alarm. For each of the
four tests
listed below it is assumed that the unit is powered on and in
Monitor Mode
(i.e. in a standard mode of
operation; see
section 5.1
).
5.6.1
Test System Modes
Test 1 (Test Mode) is performed as follows:
1.
Hold the
Test
button to Enter
Test Mode
.
The Fault and Alarm indicators will flash
blue.
2.
Confirm all output relays have latched
correctly (i.e. changed state) with use of a
digital multi-meter.
3.
Hold the
Test
button to manually exit Test
Mode and return to
Monitor Mode
, or leave
for
15 seconds
to automatically return to
Monitor Mode.
4.
Confirm all output relays have unlatched
correctly with use of a digital multi-meter.
Test 2 (Fault Mode) is performed as follows:
1.
Disconnect sensor(s) from the unit. The unit
will enter
Cable Fault Mode
(
section 5.2
).
The Fault indicator will flash amber and the
sounder will activate if enabled.
2.
Mute the panel alarm if applicable (i.e. if
DIP Switch 1
is ON
; see
section 4.1
). The
Fault indicator will change to solid blue.
3.
Confirm fault output relay has latched
correctly with use of a digital multi-meter.
4.
Reconnect sensor(s) to the unit.
5.
If
DIP Switch 2
is ON
this will clear the
fault (see
section 4.1
). Otherwise, press
the
Reset
button to exit Cable Fault Mode
back to
Monitor Mode
.
Test 3 (Alarm Mode) is performed as follows:
1.
Wet sensor(s) connected to the unit. The
unit will enter
Alarm Mode
(
section 5.3
).
The Alarm indicator will flash red and the
sounder will activate if enabled.
2.
Mute the panel alarm if applicable (i.e. if
DIP Switch 1
is set; see
section 4.1
). The
Alarm indicator will change to solid blue.
3.
Confirm alarm output relay has latched
correctly with use of a digital multi-meter.
4.
Dry the sensor(s).
5.
If
DIP Switch 2 is ON
this will clear the
alarm (see
section 4.1
); otherwise, press
the
Reset
button to exit Alarm Mode back
to
Monitor Mode
.
6.
Confirm alarm output relay has unlatched
correctly with use of a digital multi-meter.
