Siemens CRC-6 (500-033250) — Controllable Relay Card with six programmable Form C relays for FireFinder XLS, Desigo Fire Safety Modular and Cerberus PRO Modular panels.
It controls auxiliary building functions such as door-holder release, elevator capture, smoke control and lock release. The card plugs into one slot of a CC-5 or CC-2 card cage and takes an HNET address (001–251) on three rotary switches; field wiring lands on the card cage terminal blocks.
- Six SPDT (Form C) contacts: 4 A at 30 VDC/120 VAC resistive, 3.5 A at 120 VAC inductive (0.6 PF)
- Supervised relay coils; a blinking relay LED indicates coil failure
- 24 V backplane current 10 mA plus 20.5 mA per active relay; standby 51 mA plus 20.5 mA per active relay
- LEDs for power, card fail, HNET fail, 24V fail (below 18 VDC) and each relay
- UL 864 and CAN/ULC-S576 listed; FM, CSFM and NYC Fire Department approved
Card only: the CC-5 or CC-2 card cage is separate. Siemens warns that a slot previously wired for a ZIC-4A can short the PSC-12 or PSX-12 24 V output, so remove that wiring first.
