Wiring

DANGER!
Explosion and burn hazard. Do not short terminals.
Incorrect connections can result in damage to the unit and personal injury.
Before servicing this equipment, remove all power connections.
5.1

Option Bus Circuit Wiring Distance

Use four conductor, 18 AWG (0.8 mm
FACP. The total length of wire connected to the Option Bus terminals must not exceed 4000 ft
(1219 m), regardless of the wire gauge used.
The maximum length between any one device and the panel terminals depends on the current
drawn on the branch that the device is on. The current draw on a particular branch can be
found by adding together the individual current draws of each device connected to the
branch. Refer to FPA-1000 Installation and Operation Guide (P/N F.01U.173.607) for detailed
wire length calculations.

Connect the wiring to the FMR-1000-RCMD terminals. Refer to Figure 5.1.
For surface mounting with back box: Secure the base. Use the bubble level to make sure
that the back box is perfectly horizontal. Refer to Figure 4.2 on Page 8.
Fasten the annunciator unit with the four mounting screws using a Phillips (cross-
headed) screwdriver. Secure the screw for the earth ground connection. Refer to
