2D51A photoelectronic detectors use state-of-the-art optical sensing chambers and are designed to provide protection in duct applications when installed with InnovairFlex™ 4-wire duct smoke detector housings.

Expand the versatility of the InnovairFlex™ line of duct smoke detectors with System Sensor notification and test accessories.

D4240 photoelectric duct smoke detectors are 4-wire detectors that feature pivoting housings that fit both square and rectangular footprints and mount to round or rectangular ductwork.

DCOIL remote test coils are required for older DNR(W) duct detector housings.

The System Sensor DH400OE-1 is a steel enclosure for mounting a standard indoor rated duct smoke detector outdoors.

DUCTCOV covers are designed for use with DNR and DNRW duct smoke detectors.

Detector test magnets simplify detector testing and maintenance

Dispositif de test et de signalisation. Il permet d'effectuer le test d'alarme sur les détecteurs OSID et OSI-RE. Le boîtier RTS151KEYF permet le réarmement local d'un détecteur OSI-RE et OSID.
