Remote indicator TD-SL37 – LED indicator, White
The TD-SL37 is a remote indicator (LED/diode) which provides a clear visual signal when a connected alarm input is activated. It is used when you want an event to be clearly visible in a different location than where the sensor or control panel itself is located.
It is not an alarm in itself and not a sensor – without one indicator which shows the status of the facility it is connected to.
Fits multiple types of alarm systems
TD-SL37 can be used as a visual indication in several types of installations, for example:
-
Fire alarm (indication from fire detector/alarm zone)
-
Burglar alarm (indication from alarm zone, magnetic contact, PIR, etc.)
-
Telecommunication/signal and technical facilities (status indication, alarm output, error indication)
-
Other low voltage systems where you need a clear LED indication
