NOTE :
TERMINALS 20 & 21
MUST BE LINKED
Terminal 19 : Switchable power output
This terminal provides a 12V DC output of max. 0.5 Amps that is switched by the alarm on/off key switch. It can be used to supply
ultrasonic or microwave motion detectors, etc. Avoid connection of infrared detectors to a switchable power supply. The PIR
detectors should be connected to a permanent 12V power supply (terminal 21) in order to ensure stable and reliable operation.
Connect the PIR detectors as follows :
Positive connection (+) of the PIR detector to terminal 21 and the negative connection (-) to terminal 6.
FIG. 12 : TERMINAL FOR SWITCHABLE 12V POWER SOURCE
Terminal 20, 21 and 8
These terminals are used for remote key switches. If no remote key switch is used, terminals 20 and 21 should be shorted
in order to disable the internal alarm that senses wire cutting. There are two ways to connect a remote key switch to the
panel. Both methods (see diagram) will activate an internal alarm if the wiring is cut.
FIG. 13 : REMOTE KEYSWITCH WITH CUT WIRE PROTECTION
FIG. 14 : REMOTE KEYSWITCH WITH CUT WIRE PROTECTION
NOTE : The key switch on the panel should be left in the "on"-position when an external key switch is being used.
Both methods of remote key switch connection are secure : the alarm will be activated if the wiring is cut.
