MUSH-6M
Product description 
It is designed to coordinate a two-wire alarm loop (AL) with security and fire alarm systems working with four-wire SHS, as well as with AL power supply
- 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 two-wire alarm loop (AL) by a jump-like increase in resistance (decrease in current) in a chain of the PPC signal loop
- 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
