4.13 6.35 mm telejack
4.13.1 Port 1 and 2
Port 1 and Port 2 are inputs and only available if a 6.35 stereo telejack connector is
mounted on the PCB. On a stereo teleplug, Port 1 is the the tip and Port 2 is the ring.
If a mono teleplug is used, only Port 1 is available. Both ports have a common ground
and must be connected to potential free contacts (see below).

4.13.2 Tamper
If there is a plug present into the 6.35 telejack and this is removed, the unit will send
a
Tamper
alarm. If the plug is inserted again the unit sends a
Tamper OK
alarm.
No
Tamper
alarm is sent if a plug is removed or inserted during 10 seconds after
power up.
4.14 Unit supervision
The unit sends out a
Radio test alarm
every 9 hours (configurable to 1-255h or
disabled). By detecting this signal, the receiving system can see that all units are
working. After start-up the first radio test alarm will be randomized in the interval
between 1-59 minutes.
The source address in the radio message is the Unit radio Id.
If more than 19 (configurable to 1-255) radio test alarm messages are sent without
received acknowledge, the unit stops sending radio test alarms and is now i
Sleep
mode
. When in this sleep mode, any other alarm type that is acknowledged starts
the radio test alarm function again. If the parameter
Number of missed ACK before
sleep
is configured to 0 (zero), the unit never stops sending radio test alarms.
