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 2 Identify components. Examine the TSD-90A to
identify the component locations.
STEP 3 Install batteries. Connect the two 9-volt batteries
and place them into battery holding cups.
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.
STEP 5 Install mounting plate. Use the two screws and
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.
STEP 6 Program TSD-90A into receiver and test. Follow
the receiver’s instructions to set it in a program or learn mode.
Press the TSD-90A’s transmitter test button (not the smoke
alarm’s test button) to send a test signal. The transmit LED
should light. Verify that the signal was received and that the
transmitter was properly entered into the receiver’s memory.
