SpreadNet
Model SN980-SMOKE
RF Photoelectric Smoke Detector

Installation Instructions

The SN980-SMOKE is a
system type smoke detec-
tor, designed for open area
protection. The unit com-
bines a Spread Spectrum
wireless transmitter with a
photoelectric smoke detec-
tor.
Spread Spectrum technol-
ogy provides higher power,
lower noise, less interfer-
ence, and longer range
than single frequency transmitters. The RF transmitter is fully su-
pervised, ensuring reliable communications.

FEATURES

• Spread spectrum technology
• Up to 100 mW transmitter
power
• EEPROM memory
• Lithium batteries included
(1 yr. expected life)
• Simple installation

DETECTOR PLACEMENT

The SN980-SMOKE Photoelectric Smoke Detector is designed
to be either ceiling or wall mounted. When ceiling mounting the
SN980-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 personnel,
such as a Fire Alarm
Technician certified by
the National Institute
for Certification in En-
gineering Technolo-
gies (NICET), or a
Licensed Fire Protec-
tion Engineer. Location
and spacing of detec-
tors depends upon
such factors as ceiling
height, area to be cov-
ered, air flow conditions, and other conditions which may affect
response time. Additional information regarding detector place-
ment may be found in the National Electrical Manufacturers As-
sociation (NEMA) Guide for the Proper Use of System Smoke
Detectors as well as NFPA 72.

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 SN980-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).

MOUNTING

The SN980-SMOKE will mount directly to the wall or ceiling.
Do NOT mount on any type gang box.
The SN980-SMOKE must be programmed prior to permanent
mounting. Refer to the PROGRAMMING THE TRANSMITTER
section below.
To mount the SN980-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.)

To replace the head assembly, align the tamper Locking Screw
on the detector head with the Detector Head Alignment Mark
on the base. (See Figure 2 above.)
The SN980-SMOKE comes equipped with a vandal resistant
4"
(10cm)
locking feature. The Locking Screw is a 1.5mm Allen head (hex-
agonal) set screw. After installing the detector head, tighten
the Locking Screw until snug.

Max.

PROGRAMMING THE TRANSMITTER

In order to program the SN980-SMOKE, the batteries must be
activated and the detector head must be in place. The follow-
ing 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.
