The TSD-90A Supervised Photoelectric Smoke Detector 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.
