Siemens 500-033250 CRC-6 Fire Alarm Relay Card

Siemens CRC-6 Controllable Relay Card, P/N 500-033250, Rev. 02.01, is a six-relay expansion module for Siemens fire-alarm systems providing independent outputs to control building functions such as door holders, elevator capture, smoke control, and lock releases. It is designed for use with Cerberus PRO Modular, Desigo Fire Safety Modular, and FireFinder XLS panels, enabling direct integration with system logic to energize external devices as required by fire-safety scenarios. Electrical ratings for the relays are 4 A at 30 VDC or 120 VAC resistive, and 3.5 A at 120 VAC with a 0.6 PF. On 24 V logic, the current draw is specified as 10 mA + 20.5 mA per active relay, with some documentation referencing 51 mA + 20.5 mA per active relay depending on configuration.
