3. Wiring Auxiliary Devices
Use the Auxiliary Power AUX (+) COM (-) terminals to power PIRs, glass-break detectors (4-wire
types), smoke detectors, audio switches, photoelectric systems and/or any device that requires a 12V
DC power supply.
4ANote:
If the auxiliary outputs are overloaded (exceed 800/1500mA) and are shut down, you must
disconnect all loads from the outputs for a period of at least 10 seconds before you reconnect any
load to the auxiliary outputs.
4. Wiring Internal Bell
The Bell/LS terminal provides power to the internal siren. When connecting an internal sounding
device, pay attention to the polarity.
It is important to position the BELL/LS Dip Switch SW1 correctly. The position varies depending on
the type of internal siren.
Note:
To avoid bell loop trouble, if no connections are made to an internal siren, use a 2.2KΩ resistor in its
place.
5. Wiring Bell Tamper
Connect the bell tamper to the BELL TMP and COM terminals on
the main panel using 2.2KΩ resistors in serial.
