BEFORE INSTALLING
Please read thoroughly System Sensor’s
Applications Guide for System Smoke
Detectors
(SPAG91), which provides detailed information on detector spacing,
placement, zoning, wiring, and special applications. This is available online
from System Sensor’s website: www.systemsensor.com. (For installations in
Canada, please refer to CAN4-S524,
Standard for the Installation of Fire Alarm
Systems
, and CEC Part 1, Sec. 32.)
NOTICE:
This manual should be left with the owner/user of this equipment.
IMPORTANT:
The detector used with this base must be tested and maintained
regularly following NFPA 72 requirements. The detector used with this base
should be cleaned at least once a year.
GENERAL DESCRIPTION
The B110RLP plug-in detector base is used with System Sensor model 1151 and
1151A ionization detector heads and model 2151 and 2151A photoelectronic
detector heads. The capability of plugging these detectors into a variety of
special bases makes them more versatile than equivalent direct-wired models.
Refer to the System Sensor catalog for other available plug-in detector bases.
This base is intended for use in 2-wire systems, with screw terminals provided
for power, ground, and remote annunciator connections. The base also con-
tains a resistor to provide current limiting in the alarm state.
MOUNTING
This detector base mounts directly to 3-
½
- inch and 4-inch octagon boxes, and
4-inch square boxes (with or without plaster rings). To mount, remove deco-
rative ring by turning it in either direction to unhook the snaps, then separate
the ring from the base. Install the base to the box using the screws supplied
with the junction box and the appropriate mounting slots in the base. Place
decorative ring onto base, then turn in either direction until the ring snaps in
place (see Figure 1).
INSTALLATION GUIDELINES
All wiring must be installed in compliance with the National Electrical Code
and the local codes having jurisdiction. Proper wire gauges should be used.
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.
