Wiring Ann-80 To Facp - Honeywell FIRE-LITE MS-10UD Series Manual

Installation

Wiring ANN-80 to FACP

The following steps can be used as a guide to wire the annunciator. Make certain all power has been removed from the FACP prior to
annunciator installation.
1. Route wires from hole in backplate, through wiring channel and then to ANN-80 terminal block TB1.
2. Remove appropriate amount of wire insulation.
3. Connect the wiring from the FACP ANN-BUS to annunciator TB1 terminals 3 (A) & 4 (B). Make certain to connect A to A and B
to B.
4. If appropriate, connect the wiring going to the next device on the ANN-BUS to TB1 terminals 3 & 4. Make certain to connect A to
A and B to B.
5. Connect the wiring from the 24 VDC power source to annunciator TB1 terminals 1 (-) & 2 (+). Make certain to observe proper
polarity.
6. If appropriate, connect the power wiring going to the next device to terminals
1 (-) & 2 (+). Make certain to observe proper polarity.
7. After all connections are made, remove extra wire from inside of annunciator by dressing it neatly through wire channel, with any
excess wire pushed back through hole into electrical box.
The following table shows the ANN-80 connections to the MS-5UD/MS-10UD.
