- MUSH-3M module is designed to adjust 2-wire fire alarm loops with 4-wire fire alarm CP and intruder-fire CP, and also with AC CP.
- The modules provide connection of smoke detectors (SPD-3.1M, SPD-3.10, SPD-3.5, SP-2.1) and heat detectors (SPT, FT, FTL) to 4-wire control panels or to AC CP.
- The modules control current value in 2-wire circuit and depending on its value change output’s status for message transmission (Standby, Fire, and Fault) to the control panel.
- The MUSH-3M issues the Fire notification in the event of one or several detectors activation in 2-wire loop by intermittent resistance decrease (current increase) in signal circuit of CP.
- The modules issue the Fault notification in the event of short-circuit, open-circuit and 12 V outage on a module (LED is off). The fault notification is issued by 4-wire alarm loop circuit break.
- The modules provide limitation of current value in the event of short-circuit in 2-wire circuit.
- The power supply of 2-wire loop can be disabled by pressing the RESET button.
