CERBERUS PYROTRONICS SR-35 Supplementary Relay
Description
The SR-35 relay module is designed to activate or de-activate external circuit controls such as fan shutdown, door releases, and other fire related equipment. The SR-35 contains eight independent relays with 2 amp SPDT contacts. Each relay can be selected to operate either on a high going input signal from appropriate System 3 mod-ules or an open collector input signal such as those available on Cerberus Pyrotronics XL3, MXL and SXL systems. The position of actuation mode headers on each relay determines high going or low going signal activation. Power to operate the relays is provided from the 24 VDC system power supply. The SR-35 module occupies only one standard module position in the System 3 enclosure. All terminals are of the clamp type and will accommodate 2 wires of up to #14 gauge. The SR-35 is UL and ULC listed and NYMEA, FM, CSFM and City of Chicago approved.
