The TSD-1 point smoke and heat detector is designed to detect the early stage of a developing fire. Equipped with a photoelectric visible smoke detector and an excessive differential temperature sensor, it ensures high sensitivity and non-directionality.

The precise Hexamesh stainless steel filter protects against dirt and small insects. Its connection to alarm control panels with a 12 V power supply is made easy thanks to the configuration using micro-switches and built-in parametric resistors.
