MUSH-1
MODULE
MUSH series modules are designed to connect 2-wire fire alarm loops to an intruder-fire CP as well as to a AC fire alarm CP.
MUSH-1 is used with SPD-3 series smoke detectors (SPD-3.1M, 2-wire SPD-3.10), SPD-3.5, SPT-2B, SPT-3B heat detectors, FT series heat detectors.
MUSH-1 issues the Alarm signal by alarm loop circuit break when short-circuit, open-circuit or detectors activation occur.
