• The multi detector contains one photo-electric (optical) smoke detector and one heat detector within the low profile housing
• The latest IC technology will secure the highest reliability possible
• It has unleaded soldering
• The smoke detection chamber has a high-efficient optical system with an infrared light LED and a photodiode with two lenses
• Light reflection is used to detect smoke, which enters the detection chamber through an insect filter and an optical labyrinth
• The heat sensing element is a thermistor
• The detector is supplied with two red LEDs that will be blinking when the detector has activated alarm
• It also has a green polling LED. The detector is plugged in an analogue base (3312 / 4313 / 3379)
• The COM loop is connected to the base, which also can have terminals for an external LED, e.g. BARIL
• The detector is intended for indoor use in dry premises and in the systems FT128 / FT512 / FT1020G3
