Linear fire smoke detector IP212 Trion-L2 MK (detector) is designed to detect combustion products (smoke) in fire protection systems of explosive objects and generate a "Fire" signal.
IP212 Trion-L2 MK by the principle of operation is a threshold linear two-position optical-electronic smoke detector.Installed in large rooms with high ceilings.Recommended for use in unheated rooms.

Peculiarities:
The detector consists of an infrared emitter and receiver. Both the emitter and receiver are supplied with a permanently attached cable, which connects to the corresponding switching unit. The "Fire" and "Fault" relay contacts are galvanically isolated from each other and from the power line. The detectors are connected to the alarm circuit via a short circuit (in parallel). The receiver is connected via a four-wire connection with a separate power line.
The detector is supplied with cable entries of various designs:
The cable entry connection thread is G1/2. Round cables with a diameter of 8-12 mm can be inserted into the junction box.
