Multi-voltage conventional relays are used for high-current switching applications such as fan and damper assembly control, door control, air handling unit controls, and other types of system interfacing.

L-Series horns are designed to simplify installations to provide primary and secondary signaling for fire and security applications.

The i4 module allows up to 12 i4 Series or compatible i3 Series smoke detector models to be integrated into a fire alarm panel using only 2 to 3 zones: a smoke zone, a CO zone and an optional trouble zone. Detectors sound Temp 3 for smoke and Temp 4 for CO events. The i4 module can be used to alarm all sounders in compatible detectors for smoke and CO events. When one detector detects smoke or CO and goes into alarm, all connected detectors alarm, offering the highest level of warning to the homeowner. The i4 Series Interface Module mounts to a 411/16-inch square back box for quick and easy installation. Terminal blocks with durable SEMS screws ensure a reliable connection. It also has pre-drilled holes for easy mounting inside a metal enclosure.

SS-Series smoke detectors are intelligent (addressable) detectors with point ID capability that enable each detector address to be set with rotary address switches providing exact device locations. SS-Series detectors support current SK, LiteSpeed™ and SS Protocol systems. Refer to the Addressable Detector and Sounder Base Compatibility Chart or the Intelligent Control Panel SLC Wiring Manual for specific panel compatibility. Detector sensitivity is continually monitored and reported to the fire alarm control panel. The System Sensor SS-FIRE-CO is an intelligent, multi-criteria detector incorporating photoelectric, thermal, infrared and carbon monoxide (CO) detection principles that provide both fire and CO detection. For fire, sophisticated algorithms maximize the advantages of all four sensor types creating our best detection strategy offering heightened immunity to nuisance particulate and enhanced sensitivity to real fire.

L-Series low frequency sounders include a variety of features that increase their application versatility while simplifying installation.

i³™ Series offers conventional smoke detectors with sounder, relay and isolator features included.

OSI-R-SS is a 4-wire conventional reflector-type linear optical beam smoke detector for use in fire alarm systems. The beam operates primarily on the principle of light obscuration using an infrared beam. Optical beam smoke detectors are uniquely suited to protecting buildings with large open areas with high ceilings such as a warehouse or atrium. The OSI-R-SS detector is a combined transmitter/receiver unit that can be directly connected to a conventional detector circuit.

The System Sensor L-Series and L-Series with LED Outdoor platform offers the most versatile and easy-to-use line in the industry with lower current draw and modern aesthetics. LED lighting technology offers significantly lower current draw compared to older Xenon bulbs across a full candela range. This improves design flexibility for notification appliance circuits (NACs) while also reducing power supply requirements allowing for simpler and lower cost installations. L-Series with LED can meet virtually any application requirement, including indoor, outdoor, wet, and dry applications in temperatures from -40°F to 151°F.
Flexible design options meet virtually any application requirement: wall or ceiling mount, red or white color choices, and LED color lenses for distinctive visual signaling. In addition, installers can easily adapt devices using field selectable candela, using rotary switches.
