General
The SD355(A) and SD355T(A) addressable, low-profile plugin
photoelectric detectors use a state-of-the-art photoelectric
sensing chamber with communications to provide open area
protection and are used exclusively with Fire•Lite’s Addressable
Fire Alarm Control Panels (FACPs). The SD355T(A) adds
thermal sensors that will alarm at a fixed temperature of 135°F
(57°C). Since these detectors are addressable, they will help
emergency personnel quickly locate a fire during its early
stages, potentially saving precious rescue time while also
reducing property damage. Two LEDs on each sensor light to
provide a local, visible sensor indication. Remote LED annunciator
capability is available as an optional accessory (P/N
RA100Z(A)). The SD355R is a remote test capable detector
for use with D355PL or DNR(W) duct smoke detector housings.
