MUSH-3M « Arton

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
