FREQUENTLY ASKED QUESTIONS
Q: Why do the alarm
indicator lights sometimes flash at different rates
and
sometimes be lit permanently?
A: A
slow flash
indicates a bypass condition. The respective alarm will not trigger
when the energizer is in this state. A
fast flash
indicates that the alarm condition still
persists i.e. the service indicator will flash if the battery voltage is still low. A
permanently lit
alarm indicator illustrates that a fault condition was present but is
no longer active i.e. mains has been restored and the battery has charged sufficiently
that the service indicator is permanently lit.
Q: After the
fence alarm
is activated the fence alarm indicator light does not stop
flashing even after repeatedly turning the unit on and off?
A: There is most probably a fault on the fence. Switch the energiser off and
disconnect the fence wires at the energizer. Take a short peace of HT wire and bridge
the fence-out (Red) and fence-return (Black) terminals. Connect a jumper between
the two Green terminals. Switch the energiser back on, if the fence indicates GOOD
and the fence alarm indicator is lit continuously then the energiser is working correctly
and the fault is on the fence.
Q: After the energizer lid is opened I cannot turn the energizer
on
?
A: The energiser has a built-in safety switch to avoid electrical shock. If you have to
work on the unit while the lid is removed insert jumper 4 (JP4). For use by qualified
service personnel only. It is illegal to leave this jumper inserted.
Q: When and for how long will the
siren
sound?
A: The siren will be activated by one of the following conditions: Fence Alarm, Gate
Alarm, Service Alarm or by holding the Panic button (on the keypad) in for 3 seconds.
For a permanent fault like a broken fence wire, the siren will sound for 4 minutes
(
Siren-on Time
) or until the user resets the energiser by switching it off and on again.
If the energiser is not reset then it will sound the alarm again after 4 minutes (
Siren-
off Time
). This siren on-off cycle will repeat itself 3 times (
Number Of Times The Siren
Sounds
) after which the siren will not sound unless the fault, i.e. broken wire, is
repaired.
Q: Does the electric
fence use a lot of electricity
?
A: No it does not. Typically 10 Watts and 100 hours of usage costs one unit of
electricity.
Q: How long will the energizer
run for under mains failure
conditions?
A: If the fence is free from vegetation and the battery is in good condition, typically
twenty hours.
