Satel TSD-1 Manual

TSD-1
SMOKE AND HEAT DETECTOR
The TSD-1 multisensor detector can detect the early stages of fire development when there is some visible
smoke and/or temperature rise. This manual applies to the detector with electronics version 1.5 or higher.

2. Functional description
An optical method is used for the detection of visible smoke. When the concentration of smoke in the optical
chamber exceeds a given threshold, an alarm is triggered. The smoke sensor operating parameters are
modified depending on the temperature changes recorded by the heat sensor (thermistor).
The heat sensor operates according to the requirements of Class A1R (EN 54-5). The alarm will be triggered
after exceeding a certain threshold temperature (54°C - 65°C) or in the event when the temperature rises too
rapidly (see Table 1).

If the event of an alarm, the detector output is activated and the LED lights up.
3. Installation
The detector is designed for indoor installation. In its typical applications at home or in office, the detector
should be installed on the ceiling, at a distance of at least 0.5 meters from the walls or other objects.
Do not install the detector in places with high concentration of dust and/or formation and
condensation of water steam.
The detector should not be mounted in the vicinity of heaters and cookers.
Disconnect power before making any electrical connections.
1. Remove the plastic dust cap.
2. Turn the cover counter-clockwise (Fig. 5) and remove it (Fig. 6).
