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.
