Simplex 4100-3209 — eight single-pole double-throw relay module for 4100ES fire alarm control panels.
The card gives a 4100ES eight independent Form C dry contacts the site program can drive for ancillary control such as door release, damper and fan interlock or third-party signalling. It is non power-limited, so Simplex restricts it to the expansion bay rather than the master controller bay.
- Eight single-pole, double-throw (SPDT) switches on one card
- Resistive rating 3 A at 30 VDC or 120 VAC
- Inductive rating 1.5 A at 30 VDC or 120 VAC
- One block of chassis space, a block being a 4 × 5 in. card area
- Draws 16 mA supervisory and 200 mA in alarm
- Non power-limited; expansion bay mounting only
The 3 A figure is the resistive rating and an inductive load such as a contactor coil is held to half of it. Nearby cards differ: 4100-3207 and 4100-3208 are four DPDT switches with contact feedback at 2 A and 10 A, and 4100-6033 is the three-relay alarm, trouble and supervisory module.
