3.5.1 Port 1 and 2
Port 1 and Port 2 are inputs, available if a 6.35 stereo telejack connector is mounted
on the PCB. On a stereo teleplug, Port 1 is 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).

3.5.2 Tamper
If there is a plug present into the 6.35 telejack and this is removed, the unit sends a
Tamper alarm and if the plug is inserted again the unit sends an Tamper OK alarm.
No Tamper alarms are sent if a plug is removed or inserted during 10 seconds after
power up.
3.6 Key cylinder
Valid only for KEY.
The key cylinder, used on the product KEY, enables the user to activate and
deactivate the unit by switching a key. The key cylinder is connected to Port 2 on
the PCB and controls whether IN1 and/or IN2 should be discarded when the unit is
deactivated, see "5.9.1 Input type".
