With the system in “Standby”, this will cause the control unit to beep 10 times and then after to beep
once every 5 minutes. The control unit display shows the zone number from which the low battery
signal originated and the “low battery” LED will be on. Press to clear the indication.
If the low battery signal is received when the system is armed, no alarm signal is generated but the
low battery condition will be indicated in the same way as above when you disarm the system.
A detector will continue to transmit low battery warnings regularly until the batteries are replaced.
If the “low battery” LED is on, but no zone number is displayed and only is displayed.
That means the rechargeable battery inside the control unit is run down - this may happen if the
mains power has failed and the control unit has been operating from battery power for more than
several hours. Press to clear the low battery indication. The rechargeable battery may need
replacing if it has been installed more than four years.
4.9 Wireless Detector Transmissions
To comply with advance wireless security system standard , the wireless detectors in your LS5000
alarm system must transmit several kinds of signal. In addition to normal Alarm and Tamper
transmissions, the detectors also send:
Supervisory signals – these are sent automatically every one hour, allowing the Control Unit to
monitor the status of a detector.
If, on attempting to arm the system, any detector has failed to transmit a restore signal, it will be
indicated on the Control Unit by the display showing the relevant zone and the system will not arm
e.g. if a door or window fitted with a contact detector is left open, the system will not arm.
You must check that all doors and windows fitted with door/window contact detectors are closed and
that all areas covered by PIRs are clear.
If the indication remains, you should trigger the detector which shows the fault in order to initiate the
transmission of a restore signal.
When supervisory detection is enabled (factory default OFF), any detector which misses four
consecutive Supervisory transmissions will cause the “Fault” LED to be displayed together with the
relevant zone number.
When any cordless detector is triggered, its LED will flash several times. This is because a number of
alarm signals are sent during this time to make the system more secure against radio jamming.
