MUSH-1M « Arton

Product description

The module is designed to coordinate a two-wire SPS with fire and fire protection PPCs working with a four-wire fire alarm loop.

Monitors the value of the current in the circuit of the two-wire alarm loop and, depending on its value, changes the state of the output key for the transmission of notifications "Duty mode", "Alarm" on the PPC

Ensures the formation of the "Alarm" signal by breaking the circuit of the signal loop of the four-wire fire alarm loop

Provides an optical indication of this "Alarm" state with a red indicator when:

open circuit or short circuit in the circuit of the two-wire loop;
activation of one or more detectors.

Provides optical indication of the next operating mode with a green indicator

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
