Specification - Built-in type identification automatically identifies these devices to the control panel. • Internal circuitry and relay powered directly by two-wire SLC loop. The FCM-1(A) module requires power (for horns, strobes, etc.), or audio (for speakers). • Integral LED “blinks” green each time a communication is received from the control panel and turns on in steady red when activated. • LED blink may be deselected globally (affects all devices). • High noise immunity (EMF/RFI). • The FCM-1(A) may be used to switch 24-volt NAC power, audio (up to 70.7 Vrms). • Wide viewing angle of LED. • SEMS screws with clamping plates for wiring ease. • Direct-dial entry of address 01– 159 for FlashScan loops, 01 – 99 for CLIP mode loops. • Speaker, and audible/visual applications may be wired for Class B or A (Style Y or Z).
