Control module MD-1.A/T, 1 input, 12V power supply, in the cover for the TS35 rail
Alarm module MD-1.A/T
MD-1, MD-2 and MD-4 dual-threshold alarm modules are designed to control and supply 1/2/4 of the DEX/F, DEX/A, DG/F or DG.EN type threshold gas detectors for use in the Dual Threshold Gas Detection System and Active Gas Safety System GX (ASBIG®).
The alarm module can control from one (MD-1) to two (MD-2) or up to four (MD-4) detectors. The module can control additional external optical and acoustic signaling devices and enables communication with other devices via relay outputs (or an RS-485 port for MD-1…).
Modules in MD…Z version can control a gas shut-off valve. Such module is a component of “the signalling and shut-off system” according to the requirements of the Regulation of the Minister of Infrastructure of the Republic of Poland dated April 12, 2002 on technical conditions to be met by buildings and their location (Journal of Laws 2002 No. 75 + changes).
