MUSH-3M

Product description

It is intended for matching the two-wire fire loop (FL) with security and fire control systems operating with a four-wire FL, as well as with the control system with variable-signal power supply of the FL

  • Monitors the value of the current in the two-wire fire loop and, depending on its value, changes the state of the output key for the transmission of notifications ("Standby mode", "Fire", "Malfunction") to the PC
  • Forms the message "Fire" when one or more fire detectors are triggered in the circuit of the two-wire fire loop by a jump-like decrease in resistance (increase in current) in the circuit of the signal loop of the PPC
  • Forms a "Fault" notification in the event of a break or short circuit in the circuit of the two-wire loop and in the absence of 12V power on the module (the optical indicator is turned off) by breaking the circuit of the signal line of four-wire alarm loop
  • Provides limitation of the amount of current in the event of a short circuit in the circuit of a two-wire fire alarm loop
  • Allows you to turn off the power supply of the two-wire loop using the "RESET" button
