External Devices
The information on connection and wiring of sensors and signaling devices to the modules is intended only as a
guideline. For full wiring details for a specific system, refer to the system drawings and instructions and to the
installation and wiring instructions provided with each device.
Monitor Module
The Monitor module interfaces standard contact type devices with the PRO-2000 panels via the ADI card. You
can program the module's unique address using two rotary switches located on the front of the mounting bracket.
The module monitors the contact device with a supervised input circuit. For Class B supervised circuits, a 47K
ohm End-Of-Line (EOL) resistor maintains a trickle current through the detector line. The status of the detector
line (normal, open or short circuit) latches in the module until polled by the PRO-2000 panel. A LED indicator
flashes each time PRO-2000 panel addresses the module. The module transmits, to the PRO-2000 panel, the
status of the supervised input along with the actual analog value of the supervision.
Monitor modules provide a two-wire, Class B or fault-tolerant, Class A initiating circuit for normally open contact
alarm and supervisory devices.
The module mounts into a 4" square junction box via a mounting bracket (included). Screw terminals with
clamping plates are provided for ease of wiring.
