8. ZONE TEST
8.1 WHY USE ZONE TEST
To aid commissioning and assist routine maintenance check, a non-latching ‘one man test’ facility is
available.
When a detector or manual call point is triggered on any zone in Test, the Alarm sounders operate for
approximately seven seconds on and seven seconds off. This cycle continues until the cause of the
Alarm is removed (either by the test smoke clearing from the detector or the manual call point being
reset), at which point, the detector circuit also automatically resets.
Should an Alarm occur on a zone that is not programmed to test, the Alarm will be processed in the
normal way. The testing of the zone in test will temporarily be suspended until the Alarm(s) from the
other zones are reset. At this point, zone retesting may resume.
8.2 TO PROGRAMME ZONE IN TEST
NOTE: Only
one zone
can be programmed in test at any one time.
1. Insert and turn control key to enabled position;
2. Press engineer switch until the General Zone test LED is on (flashing fast);
3. Enter Engineer Code 4114 and then the General Zone Test LED is on (flashing slow);
4. Press scroll switch and Zone one fault LED will flash in synchronisation with the General Zone
test;
5. Press scroll button to the desired Zone for test. Once the desired Zone LED is flashing, this
Zone is now in test mode.
6. Once testing of that zone is completed, press scroll button to move to another Zone or turn the
control key switch to off position to exit test mode.
9. GENERAL FAULT FINDING
9.1 ZONE FAULTS
Open circuit faults will be indicated by zone(s) fault LED flashing. In case of a short circuit fault, then
the Zone(s) Fault LED will be accompanied by the Short Circuit Fault LED. In both cases, the
internal Fault Buzzer will sound and the General Fault LED will be lit.
The Zone Faults are non-latching faults. That is, if the fault disappears, the panel will automatically
reset itself. (After a short delay of up to a minute)
Suggested Action
a)
Disconnect the wiring for the zone showing fault, and refit the end of line diode at that zone
terminal in the panel. If the fault condition for that zone clears, this confirms there is a wiring
fault.
b)
Double-check the wiring and the end of line diode on the zone. Trace the fault with
consideration for the type of fault indicated.(HINT: splitting the cable half way down the zone,
and fitting the end of line diode to the new end point helps to determine which section of cable
is giving the fault)
Note: A common fault is a detector head badly seated in a base that is not making the
connection.
c)
A short circuit on a zone could be caused by the end of line diode being fitted backwards.
d)
Check that the detectors are compatible with this FACP. Note that some makes of detector will
require a series resistor or diode to be fitted to work properly. There is usually a spare
connector on the base to accommodate this (check instructions that came with the detector).
e)
Measure the resistance of the zone cabling (Remove from panel and short out end of line).
Ideally this should be less than 50 ohms. Above 70 ohms may cause an open circuit fault.
