considerations
The SN982-SMOKE is a system type
smoke detector, designed for open
area protection. The unit combines
a SpreadNet
®
Spread Spectrum
wireless transmitter with a photoelec-
tric smoke detector.
Spread Spectrum technology pro-
vides higher power, lower noise, less
interference, and longer range than
single frequency transmitters. The
RF transmitter is fully supervised, en-
suring reliable communications.
WHERE NOT TO PLACE THE DETECTOR
When selecting a mounting location, avoid areas containing large
metal surfaces, which could affect the RF transmitter. Always test
the transmitter prior to permanently mounting it to verify signal
reception.
Avoid placing the SN982-SMOKE in areas where smoke or steam
may affect operation, such as kitchens, bathrooms, near wood stoves
or furnaces. Also avoid areas such as garages, attics, and areas
where ambient temperature may exceed 100° F (37.8° C).

FEATURES
DETECTOR PLACEMENT
The SN982-SMOKE Photoelectric Smoke Detector is designed
to be either ceiling or wall mounted. When ceiling mounting the
SN982-SMOKE, be sure to mount the detector near the center of
the room, if possible. Do not place the detector less than 4" (10
cm) from the nearest wall. If wall mounting, do not mount within 4"
(10 cm) of the ceiling. (See Figure 1.)
Detector placement should be established by qualified person-
nel, such as a Fire Alarm Technician certified by the National In-
stitute for Certification in Engineering Technologies (NICET), or a
Licensed Fire Protection Engineer. Location and spacing of de-
tectors depends upon such factors as ceiling height, area to be
covered, air flow conditions, and other conditions which may af-
fect response time. Additional information regarding detector
placement may be found in the National Electrical Manufacturers
Association (NEMA) Guide for the Proper Use of System Smoke
Detectors as well as NFPA 72.
MOUNTING
The SN982-SMOKE will mount directly to the wall or ceiling.
Do NOT mount on any type of gang box.
The SN982-SMOKE must be programmed prior to permanent
mounting. Refer to the
PROGRAMMING THE TRANSMITTER
section below.
To mount the SN982-SMOKE, remove the detector head from
the base by turning the head counterclockwise. Mount the de-
tector base using #6 - #8 (M 3.5 - M 4) mounting screws. (See
Figure 2 below.)

The SN982-SMOKE comes equipped with a vandal resistant
locking feature. The Locking Screw is a 1.5mm Allen head (hex-
agonal) set screw. After installing the detector head, turn the
locking screw clockwise six to eight turns and then check that
the head is locked in position.
PROGRAMMING THE TRANSMITTER
In order to program the SN982-SMOKE, the batteries must be
activated and the detector head must be fitted to the base.
The following procedure outlines the steps for programming
the detector:
1 - Separate the detector head from the base as described in
the
MOUNTING
section.
2 - Remove the Battery Tab (see Figure 2 for Tab location).
3 - Replace the detector head, as described above. This will
enable the transmitter circuitry.
IMPORTANT:
There is no power to the transmitter with the
detector head removed.
