PROGRAMMING THE TRANSMITTER
(continued)
4 - Remove the back cover (dust cover) from the detector base
by inserting a small screwdriver into one of the slots at the
edge and gently lifting the cover.
5 - To release the Transmitter PCB, press the PCB Retaining
Latch and gently lift the board out of the base.
Be careful
not to bend the antenna.
6 - Connect the SN900-PROG RF Programmer to J1 on the
transmitter PCB. (See Figure 3 for location of J1.) Complete
programming information may be found in the SN900-PROG
Programming Manual (P/N 5-051-136-00).
7 - After programming the transmitter, carefully replace the PCB.
Fill out the Transmitter Device ID Label (supplied with the
unit) and apply the label to the rear dust cover.

NOTE:
Only one (1) SN982-SMOKE may be connected per
zone. When using the SN910-RCVI/O, all devices
must use Device #1.
APPLICATIONS
The SN982-SMOKE can be used in all areas where Photoelectric
Smoke Detectors are required. It is best suited for smoldering fires.
CAUTION:
The SN982-SMOKE is not an alarm signal-
ling device. For proper operation, this detector
MUST
be used in conjunction with an alarm signalling system,
consisting of the SN912-RCV, SN913-I/O, an approved
control panel and approved signalling device(s).
OPERATION
The detector uses an LED light source and silicon photodiode
receiving element. In normal conditions, the light from the puls-
ing light source does not strike the photodiode. In the event of
a fire, smoke enters the detector chamber, causing light from
the LED source to be reflected off the smoke particles to the
photodiode. The amount of light received is proportional to
the density of the smoke particles.
The received light is converted into an electronic signal. The
signal is compared to a fixed reference. When three consecu-
tive signals exceed the reference level within a specified time
period, an alarm signal is generated.
TESTING THE INSTALLATION
When installing the SN982-SMOKE, you can perform a functional
test of the alarm circuitry by using a test magnet. The test is per-
formed as shown in Figure 4 below.
Test Magnet
Figure 4
Testing with the Test Magnet
The SN982-SMOKE must be programmed and operational prior
to testing. Remember, alarm signals are annunciated by the con-
trol panel, not the detector.
Place the test magnet as shown in Figure 4 for at least 15 sec-
onds. The system should signal an alarm condition.
NOTE:
An alarm signal generated using the test magnet does
not assure an alarm response in the event of a hazard-
ous fire condition. Additionally, this test does not check
the ability of smoke to enter the chamber, nor accurately
test the sensitivity of the device.
Transmitter Device ID
The following procedure is recommended for mounting the label:
1 - Replace the back cover on the SN982-SMOKE.
2 - Remove the adhesive backing from the label and place
the label on the back cover.
3 - Mount the detector as described previously.
A sample of a completed Transmitter Device ID label is shown
below:
