Cofem’s MDA1Y Module<\/strong> is a microprocessed, addressable device that is easily integrated into the detection system loop. This module allows a relay to be controlled accurately and reliably, expanding the functionality of the system by providing an immediate response to various situations. With a short-circuit isolator, it ensures communication stability and continuity of system operation, providing a simple and efficient solution for external device control.<\/p>\n

The module is powered by the loop connection, but requires a 30V auxiliary power supply to provide the necessary power to the devices governed by the relays.  It supervise the voltage presence in the auxiliary supply line of 30V and in the output of the supervised relays.<\/p>\n

The module is protected by a 0.9 A self-rearming fuse and each supervised output is protected by a 0.5 A fuse.<\/p>\n

The blinking of the transparent red LED indicates communication with the control panel. The green LED lights up to indicate the tripping of one or both relays.<\/p>\n

It is a module with simultaneous activation (with a single function) of two outputs relay  , both in its type of application (siren, activation or pre-alarm), as well as in its timing and combination of sensors that activate them.<\/p>\n

Relay output R1 is supervised by means of a 33 kO line terminating resistor, indicating open or crossed line status.  The R2 output relay operate as a dry contact NO and NC, not supervised, It is usually used to activate the fire-resistant doors electromagnets. Considering the consumption produced on the system, it is recommended to install external power supplies (FAE) for more than 10 electromagnets in total per plant.<\/p>\n

The device is supplied in a rectangular, heat-resistant ABS box, to be mounted on surface or on DIN rail.<\/p>\n

The MDA1Y module is certified in accordance with Standard EN 54-18 by AENOR, and has CE marking in accordance with European Construction Products Regulation (EU) No. 2024\/3110.<\/p>\n<\/div>\n<\/div>\n
