MHG 231

Optical Smoke Detector

The MHG 231 Optical Smoke Detector is a conventional fire detector with voltage characteristics.

The MHG 231 Optical Smoke Detector is a conventional fire detector with voltage characteristics. In conjunction with the central control units of the electric fire signalling system LITES it is intended for an automatic signalling of fire occurrence as a detector responsive to fouling – to both visible and invisible smoke particles (aerosols).

The MHG 231 detector is to install at places where occurrence and concentration of smoke is assumed. The detector is responsive to fouling – to both visible and invisible smoke particles(aerosols) – on the principles of detection of scattered infrared radiation.

The MHG 231 detector is to install in the socket MHY 734.029. It is possible to connect it to the central control units MHU 113, MHU 108, MHU 106 with the loop unit JSM-5, or to theaddressable central control units of the electric fire signalling system LITES by means of the addressing unit MHY 409. It is also possible to attach the signal lighting units MHS 409, MHS408 (parallel signalling).

For its use in the electric fire signalling system the detector is liable to the agreement examination according to law No. 22/1997 Sb., in wording law No. 71/2000 Sb. and the relevant orders of the government.

It fulfils the requirements of the European standard specification EN 54 – 7.
