DESCRIPTION The TSD-90A is a high quality,

photoelectric smoke alarm with a built-in supervised
digitally-coded radio transmitter. The TSD-90A is supervised
to monitor alarms, restorals, low battery, status, tamper, and
test conditions. The TSD-90A transmitter is compatible

with any Linear SX format supervised security receiver.

The TSD-90A sounds a local alarm as soon as smoke is
detected. Twenty seconds after the local alarm sounds, the
TSD-90A’s transmitter will send an alarm signal to the
supervised receiver. The alarm signal will be repeated every
20 seconds as long as smoke is still present. A restoral report
will be sent when the smoke detection chamber clears.

Supervisory status reports are sent from the TSD-90A every
hour.

Coding switches are not required or used in the TSD-90A.
Each transmitter is pre-coded at the factory to a unique code.
With the SX format, there are more than sixteen million codes
possible.

The smoke alarm and transmitter are powered by two 9-volt
batteries. These batteries are supplied with the transmitter
and can power the unit for up to two years. If the battery
voltage drops below a preset level, a low battery report is sent
to the receiver with any status, alarm, tamper or test
transmission.

NOTE: After replacing batteries, press transmitter test button
to reset “low battery circuit”.

STEP 1 Remove mounting plate. Remove the TSD-90A

mounting plate by turning the plate counterclockwise.

STEP 4 Pick smoke alarm location. Referring to the

NFPA standard on the back of this sheet, select a good
location to mount the TSD-90A. Mounting the TSD-90A on

foil-backed wallpaper or on a metal single-gang electrical
box is not recommended because the radio range will be
reduced.

anchors provided to attach the mounting plate to the wall or
ceiling. Alternately, the mounting plate can be attached to a
plastic single-gang electrical outlet box. For the best radio range,
observe the “best signal” label on the bottom of the unit.

NFPA 72 STANDARD FOR SMOKE ALARM LOCATION

The TSD-90A should be installed in accordance with National Fire Protection Association
(NFPA) Standard 72, which reads as follows:
2-1.1.1 Smoke alarms shall be installed outside of each separate sleeping area in the
immediate vicinity of the bedrooms and on each additional story of the family living unit
including basements and excluding crawl spaces and unfinished attics. In new construction,
a smoke alarm shall be installed in each sleeping room.

2-1.1.2 For family living units with one or more split levels (i.e., adjacent levels with less
than one full story separation between levels), a smoke alarm required by 2-1.1.1 shall suffice
for an adjacent lower level, including basements. (Exception: Where there is an intervening
door between one level and the adjacent lower level, a smoke alarm shall be installed on the
lower level.)



Ceiling mounted smoke alarms should be located in the center of the room or hall, or not
less than 4 inches from any wall. When the alarm is mounted on a wall, the top of the
alarm should be 4 to 12 inches from the ceiling.



Do not install smoke alarms where normal ambient temperatures are above 100°F
(37.8°C), or below 40°F (4°C). Also, do not locate alarm in front of air conditioners, heating
registers, or other locations where normal air circulation will keep smoke from entering
the detector.

A-2.5.2.1 Smoke Detection - Are More Smoke Alarms Desirable? The required number
of smoke alarms might not provide reliable early warning protection for those areas separated
by a door from the areas protected by the required smoke alarms. For this reason, it is
recommended that the householder consider the use of additional smoke alarms for those
areas for increased protection. The additional areas include the basement, bedrooms, dining
room, furnace room, utility room, and hallways not protected by the required smoke alarms.

STEP 8 Test smoke alarm. Set the receiver into a test

mode. Press and hold the smoke alarm test button. Continue
to hold the test button for at least 30 seconds after the
noisemaker starts. Verify that the signal was received.

The installation of smoke alarms in kitchens, attics (furnished or unfurnished), or garages is
not normally recommended, as these locations occasionally experience conditions that can
result in improper operation.

The purpose of an early warning smoke alarm is to detect the presence of fire in its early
stages, and sound an alarm giving the occupants more time to exit the premise before the
smoke reaches a dangerous concentration level.
Fires start even with the best of housekeeping and fire prevention procedures. Fire is an
unexpected event. Early warning detection alerts occupants in time to act.
KNOW FIRE HAZARDS. No detection device can protect life in all situations. Therefore,
safeguards should be taken to avoid such potentially dangerous situations as: smoking in
bed, leaving children home alone, cleaning with flammable liquids such as gasoline.
The best fire protection is minimizing fire hazards through proper storage of materials and
general good housekeeping techniques. A cluttered basement, attic, or other storage area is
an open invitation to fire.
Careless use of combustible materials and electrical appliances, or overloading of electrical
outlets are other prime causes in starting fires.
It is most important that explosive and/or fast burning materials be eliminated from the home,
if at all possible.
Even after proper precautions have been taken, fires can start. Be prepared.
IN CASE OF FIRE. Leave immediately. Don’t stop to pack or search for valuables. In heavy
smoke, hold your breath and stay low - crawl if necessary. The clearest air is usually at the
floor.
Smoke alarms are not to be used with detector guards unless the combination has been
evaluated and found suitable for the purpose.

FIRE PREVENTION AND ESCAPE

STEP 9 Complete receiver programming. Refer to the

instructions supplied with the supervised receiver to program
the TSD-90A as a 24-hour fire alarm. Repeat the previous step
to verify that the TSD-90A triggers the correct zone on the
receiver and that the correct report is sent to the central station
(if the system is monitored).

If you have to go through a closed door, carefully feel the door and door knob to see if undue
heat is present. If they seem relatively cool, brace your foot against the bottom of the door
with your hip against the door and one hand against the top edge. Open it slightly. If a rush
of hot air is felt, slam the door quickly and latch it. Unvented fire tends to build up considerable
pressure. Be sure all the household realizes and understands this danger.
Use your neighbor’s phone or a street fire alarm box. The job of extinguishing the fire should
be left to the professionals. Too many unforeseen things can occur when inexperienced
people try to extinguish a fire.
BE PREPARED. Perform fire drills regularly. Use them to assure recognition of an alarm
signal. For your protection, simulate different circumstances (smoke in hall, in living room,
etc.). Then have everyone react to the situation.
Draw a floor plan and show two exits from each room. Frequently a knotted rope or ladder
from a window will serve this purpose. It is important that children be instructed carefully,
because they tend to hide in times of crisis.
It is imperative that one meeting place outside the home be established. You should insist
that everyone meet there during an alarm. This will eliminate the tragedy of someone
reentering the house for a missing member who is actually safe.
If you have children and/or invalids residing in your household, you can help your fire
department. Most fire departments have window decals available for use in children’s or
invalid’s bedrooms. Properly used, these decals will quickly identify sleeping quarters of these
individuals and show the fire department where to look first for members of your household.

IMPORTANT !!!

Linear radio controls provide a reliable communications link and fill an important need in portable wireless
signalling. However, there are some limitations which must be observed.

1 For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as Part 15

devices. As such, they have limited transmitter power and therefore limited range.

1 A receiver cannot respond to more than one transmitted signal at a time and may be blocked by radio signals

that occur on or near their operating frequencies, regardless of code settings.

1 Changes or modifications to the device may void FCC compliance.
1 Infrequently used radio links should be tested regularly to protect against undetected interference or fault.
1 A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale distributor or

dealer, and these facts should be communicated to the ultimate users.
