MUSH-2. Products. Arton

The module is designed for the match of a 2-wire alarm loop with fire and intruder-fire control panels operating with a 4-wire alarm loop.

The module forms the “Alarm” signal for a control panel and induces this status by a red optical indicator when detecting the following events:

The forming of the “Fire” signal is performed by open-circuit of a signal line in a 4-wire loop.

The module provides:

Modules allow disconnecting the power supply of a 2-wire loop for a short duration with the help of the discharge button.
