EBI and EBFI
Plug-in Detector Bases
INSTALLATION AND MAINTENANCE INSTRUCTIONS
BEFORE INSTALLING
Please thoroughly read the system wiring and installation manuals and the
System Smoke Detector Application Guide, which provides detailed informa-
tion on detector spacing, placement, zoning, and special applications.
NOTICE: This manual should be left with the owner/user of this equipment.
MOUNTING
Detector base, Model EBFI (Figure 1A), mounts directly to 3
1 ⁄ 2 -inch and 4
-inch octagon boxes, 4-inch square boxes (with or without plaster rings) and
single gang boxes. To mount, remove the decorative ring by turning it in either
direction to unhook the snaps, then separate the ring from the base. Install
the base on the box using the screws supplied with the junction box and the
appropriate mounting slots in the base. Place the decorative ring on the base
and rotate it in either direction until it snaps into place.
Detector base, Model EBI (Figure 1B), mounts to 3 1 ⁄ 2 -inch octagon boxes,
4-inch square boxes with plaster rings, and European boxes with 50, 60, and
70 mm screw spacing. Install the base on the box using the screws supplied
with the junction box and the appropriate mounting slots in the base.

WIRING
All wiring must be installed in compliance with all applicable local codes and
any special requirements of the authority having jurisdiction, using the proper
wire size.
The conductors used to connect smoke detectors to control panels and acces-
sory devices should be color-coded to reduce the likelihood of wiring errors.
Improper connections can prevent a system from responding properly in the
event of a fire. For signal wiring (the wiring between interconnected detec-
tors), it is recommended that the wire be no smaller than AWG 18. However,
the screws and clamping plate in the base can accommodate wire sizes up
to AWG 12. If shielded cable is used, the shield connection to and from the
detector must be continuous by using wire nuts, crimping, or soldering, as
appropriate, for a reliable connection.
See Figure 2 for proper base wiring. Make electrical connections by stripping
about
3 ⁄
8
of an inch (10 mm) of insulation from the end of the wire (use strip
gauge molded in base), sliding the bare end of the wire under the clamping
plate, and tightening the clamping plate screw. Do not loop the wire under the
clamping plate. The wiring of the detector base should be checked before the
detector heads are installed in them. The wiring should be checked for conti-
nuity and polarity in the base, and dielectric tests should be performed. The
base includes a space for recording the zone, address, and type of detector
being installed. This information is important to set the address of the detector
head that will later be plugged into the base and to verify the type required
for that location.
