MUSH-4

MODULE

The module is designed to receive alarm messages from SP-2.4 detectors, separately from upper (AL1) and lower (AL2) sensors, continuity control of AL1 and AL2 and transmission ALARM and FAULT signals to FACP with galvanic outputs.

The module provides:

-          voltage stabilization  for 15/24 V AL (set by a user with the “15/24 V” switch on the module PCB);

-          current restriction when short-circuit occurs in AL;

-          automatic deenergizing of AL1 and AL2 on  detecting short-circuit in any of them;

-          storage of current in AL1 and AL2 corresponding to the normal state;

-          indication of statuses “NORM”, “FIRE”, “SHORT-CIRCUIT”, “OPEN-CIRCUIT” separately for AL1 and AL2;

-          manual resetting simultaneously of AL1 and AL2;

-          decrease of the resistance value between screw contacts “Tr1+”- “Tr1-” and (or) “Tr2+”- “Tr2-” when  the alarm condition occurs correspondingly in AL1 and (or) AL2;

-          increase of the resistance value between screw contacts “Av1+” – “Av1-“ and (or) “Av2+” – “Av2-“ when any fault occurs correspondingly in AL1 and (or) AL2 and the module is deenergized.
