Fire-Lite B350LP User Manual
B350LP PLUG-IN DETECTOR BASE
INSTALLATION INSTRUCTIONS
Before installing detectors, please thoroughly read the system wiring and installation manuals, and manual I56-407,
Guide for Proper Use of System Smoke Detectors,
zoning, and special applications. Copies of these manuals are available from Fire•Lite.
GENERAL DESCRIPTION
The B350LP Plug-in Detector Base is used with Fire•Lite models CP350 ionization, SD350 and SD350T photoelectronic detectors, and H350 and H350R heat detectors
The B350LP base is intended for use in a 2-wire addressable system, with screw terminals provided f or power (+ and –),
and remote annunciator connections. Communication takes place over the power (+ and –) lines.

This detector base 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 decorativ e 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 scre ws 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 (see Figure 2).
INSTALLATION WIRING GUIDELINES
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 accessory 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
detectors), 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. The use of twisted pair wiring or
shielded cable for the power (+ and –) loop is recommended to minimize the effects of electrical interference.
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.
Make electrical connections by stripping about 3/8
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 zone wiring of the detector base should be checked before the detector heads are installed in them. The wiring
should be checked for continuity and polarity in the base, and dielectric tests should be performed.
The base includes a label for recording the zone, address, and type of detector being installed. This inf ormation 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.
