The MHG 664 interactive and autonomous linear smoke detector with servomotors for optics adjustment and laser pointer is intended for automatic fire alarm signalling as smoke detector in analogue addressable and conventional Fire Detection and Fire Alarm System LITES.

It is intended to indicate a rising fire on the principle of reducing the infrared ray trough smoke particles. Linear smoke detector is placed at locations of anticipated smoke occurrence and
concentration.

Interactive Linear smoke detector MHG 664 in a reflex version is intended for up to 100m. It consists of transmitter and receiver on a printed circuit board, which is along with the optical
system placed in a plastic box with an aperture for the infrared ray. The detector is equipped with servomotors and laser pointer for optics adjustment.

To each detector is connected the Indicating preparation MHY 740. For adjustment of the detector serve the preparations MHY 536, MHY 537 or MHY 538, which also serve as a control
unit for autonomous use of the detector.

The detector operates in regimes:

• interactive using analogue communication with C.I.E. MHU 110, MHU 111, MHU 115, MHU 116,MHU 117,
• interactive with contact outputs Alarm and Fault for connection to conventional C.I.E.,
• interactive with contact outputs Alarm and Fault for autonomous regime or for connection to C.I.E.of other manufacturers.
