4. How to use
The detector’s PCB and battery holder are placed in a plastic enclosure with a removable
cover (Figure 1).
A magnetically controlled switch (reed switch), a tamper switch, a multi-color LED indicator
and RESET contacts to initiate the process of binding with the Lun-R radio are placed on the detec-
tor’s PCB.
Figure 1. Detector, its cover and magnet
Depending on external actions, the detector transmits the following events to the Lun-R re-
ceiver:
●
If the magnet is located near the detector housing, in the area marked by risks, then the
reed switch is closed and the
norm
event of the detector is generated;
●
If the magnet is moved away from the housing or moved away from the marked position,
the reed switch opens and detector generates an
alarm
event;
●
If the housing cover is opened, the tamper will be triggered and the
tamper alarm
event
will be generated;
●
If the voltage of the battery drops to 2.2V or lower – the event "
Battery low
" is generated.
In addition, the detector transmits periodic test signals to the receiver to confirm its operabil-
ity. When the test signals stop, the control panel generates the
detector communication lost
event.
When the communication loss with the receiver, the detector continues to search it. Therefore,
when you turn off the receiver or control panel for a long time, it is recommended to remove the
detector’s battery.
