MMD-509 / CO Module for expanding system

Referencia: MMD-509

Description

The MMD-509 is a CO module for expanding the system. Each module allows connection of up to 32 detectors connected to 2 wires without polarity, with a maximum distance of 1 Km. The module has three programmable level relays, extraction 1 and extraction 2 and alarm.

Each module includes a display showing the CO concentration of the zones. Each of them can control the air renewal group manually or automatically. The automatic control lets you work in an advanced mode in which the overall system's power consumption is reduced. In order to obtain this reduction, the module performs algorithms to minimize the air renewal output activations by taking the individual measurement of each detector in the zone.

Each zone module lets you connect up to 32 DMD-500 or DMDP-500 carbon monoxide detectors. The connection to the module is done through 2 wires, the detectors may be distributed along 2,000 meters in length and each detector covers 200 m2; this value is defined as the maximum surface in current legislation.
