When smoke is present, these alarms warn you with loud beeps and flashing lights. Use them alone or link several together so that if one detects smoke, they all go off in tandem. They install directly into your facility’s electrical system. These alarms also have a backup battery to keep them working during power outages. Due to import regulations, they cannot be sold to Canada.

When smoke curls or carbon monoxide rises, these alarms sound off. They have built-in sensors, so you don’t need to connect them to a fire detection system. All have voice alerts that explain why the alarm is sounding.

Alarms with Wi-Fi connection pair with an app on your smartphone, so you can respond to an emergency even when you’re offsite. They send you notifications if they detect a hazard or the battery is running low. These alarms cannot be sold to the listed areas due to product registration requirements.

Alarms with tandem signaling can be linked together so that if one spots smoke or carbon monoxide, they all go off. They install directly into your facility’s electrical system. All have a backup battery to keep them working during power outages.

Detect the presence of smoke in ducts and shut down HVAC units to avoid circulation. These sensors and controllers have standard RJ45 connections, so they work with most alarm systems and quickly snap in without needing to connect individual wires to terminals. UL and C-UL listed as well as FM and MEA approved, they meet strict safety standards. Choose from a sensor, controller, or sensor and controller unit.

Sensors measure rapid changes in air flow from smoke and fire but won’t register dust and debris, so they won’t cause a false alarm.

Controllers send signals from your sensor to a fire alarm control panel, which closes HVAC dampers when smoke is detected. Controllers can be installed up to 15 ft. away from your sensors and connected with cable. Connect up to two sensors per controller to monitor two sections of ductwork.

Sensor and controller units come with one controller and one sensor. Connect another sensor to cover another spot in your HVAC system.

Sensors require sampling tubes (sold separately) to bring in air from the duct. Mount the sampling tube inside the duct and connect it to the sensor on the outside of the duct by drilling a hole with the included template. For duct up to 36" wide, the sampling tube’s length should be 2/3 the width of the duct.

If your smoke detectors are hard to access, use remote test stations (sold separately) to check that they’re working properly from a convenient location.
