17 + INT SIREN Positive (+) side of interior siren connection. 12 VDC@100 mA maximum. Other side
to - INT SIREN terminal 18. Connect multiple piezos in parallel. A 1N4001 diode (in
series) is required at each piezo location. A 4.7K ohm EOL resistor (in parallel) is reqi-
uired at the peizo or at the last peizo in a chain (see wiring diagram). This terminal nor-
mally measures zero volts (to GND).
18 - INT SIREN Negative (-) side of interior siren connection. 12 VDC@100 mA maximum. Other side
to + INT SIREN terminal 17. This terminal normally me12 volts (to GND)
when siren is off. This is the normal monitoring (supervision) voltage.
19 GND Interrogator 200 AVM microphone (listen-in) common ground connection
20 AVM MIC Interrogator 200 AVM microphone (listen-in) connection
WARNING!
The maximum number of microphones to be connected to terminals 19 and 20 is two.
Connect multiple microphones in parallel.
