The SIGA-CT2 dual input module connects to data in and data out loops from the fire alarm control panel or previous devices via terminal block 1. Terminal block 2 connects to two separate initiating device circuits containing typical normally open devices terminated with forty-seven kilohm end of line resistors. The module includes red and green LEDs indicating alarm or active and normal states respectively.
