BEFORE INSTALLING
Please read the System Smoke Detectors Application Guide, which provides
detailed information on detector spacing, placement, zoning, wiring, and spe-
cial applications. Copies of this application guide are available from System
Sensor. NFPA 72 guidelines should be observed.
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 should be cleaned at
least once a year.
GENERAL DESCRIPTION
The B501 is a plug in detector base intended for use in an intelligent system
with screw terminals provided for power (+) and (–), and remote annuncia-
tor connections. Communication takes place over the power (+) and (–) lines.

MOUNTING
This detector base mounts directly to 4 inch square with plaster ring, 3.5 inch
octagon, 50 mm, 60 mm, and 70 mm centers.
INSTALLATION AND WIRING GUIDELINES (SEE FIGURE 2)
All wiring must be installed in compliance with all applicable local codes
and any special requirements of the local authority having jurisdiction. Proper
wire gauges should be used. 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 and modules),
it is recommended that the wiring be no smaller than 18 AWG (0.823 square
mm). Wire sizes up to 12 AWG (3.31 square mm) may be used with the base.
Alarm system control panels have specifications for allowable loop resistance.
Consult the control panel specifications for the total loop resistance allowed
before wiring the detector loops.
Make wiring connections by stripping about
from the wire end (use strip gauge molded in base). Then slide the wire under
the clamping plate and tighten the clamping plate screw. Do not loop the wire
under the clamping plate. (see Figure 3)
Check the zone wiring of all bases in the system before installing the detec-
tors. This includes checking the wiring for continuity, correct polarity, ground
fault testing and performing a dielectric test.
The base includes an area for recording the zone, address, and type of detec-
tor to be installed at that location. This information is useful for setting the
detector head address and for verification of the detector type required for
that location.
Once all detector bases have been wired and mounted, and the loop wiring
has been checked, the detector heads may be installed in the bases.
