Hardwired Smoke Detectors

Link multiple detectors in tandem to warn occupants outside the vicinity about potential fire hazards; if one unit is activated, they're all activated. These detectors produce their own signal when visible smoke particles are detected. A backup battery provides protection in case of power failure. They cannot be sold to Canada due to import regulations.

Fire Alarm Control Panels

Connect and monitor your fire alarm system. Control panel comes with all the circuitry needed to power and monitor devices for up to five zones. These devices can include up to 30 smoke or carbon monoxide detectors as well as an unlimited number of heat detectors and fire alarm stations. Indicators show the status of each zone. The control panel has one relay for connecting alarms such as buzzers, bells, and lights.

Thermal Imaging Cameras

Detect hot spots, leaks, moisture problems, and construction defects invisible to the eye. These imaging guns translate thermal energy into a color image that indicates hotter areas as brighter and cooler areas as darker, so it’s easy to identify and diagnose problems on instrument panels, HVAC systems, and other equipment. To review footage at a later date, use them to take photos and videos. The lower a camera’s thermal sensitivity, the more precise heat differences it will detect for more detailed images. All are CE marked as meeting European standards for health, safety, and environmental protection. Some include a calibration certificate traceable to NIST stating they’ve passed a test for accuracy.

Adjustable Emissivity—For Dark, Dull, Light, Shiny Surfaces

FDA compliant cameras are approved for use alongside other screening devices to detect differences in skin surface temperature. Use screening mode to scan large crowds of people, and these cameras will notify you when someone’s temperature is above your specified range. Draw a square around a specific area to get its average temperature with the area box function, or target a specific object with the spot meter feature. A laser sight tells you how far you are from your target, so you know you’re standing at a safe distance. Record verbal notes for documentation with the built-in microphone. These cameras connect to computers via Bluetooth, Wi-Fi, or a USB cable for quick data transfers.

Use cameras with a 2732° F maximum temperature in facilities with extremely hot equipment such as boilers and steam systems. A one-touch level/span function lets you focus on a single area by tapping the touch screen, giving you a temperature span and contrast level specific to that area. These cameras have a 180° rotating lens, so you can get a clear view of your target from any angle.

Heat Stress Monitors

Measure temperature, humidity, and radiant heat in your work area to keep your team safe from heat-related hazards. These monitors help you avoid dangerous conditions and comply with OSHA standards for a safe work environment. They use a variety of measurements from your surroundings to calculate the heat stress index and the wet bulb globe temperature (WBGT), which tell you how hot it feels. Set a maximum wet bulb globe temperature, and an alarm will go off when heat reaches the safety limit.

These monitors have two sensors. One measures temperature, humidity, dew point, and wet globe temperature. The other measures black globe temperature, which is the effect of direct solar radiation on an exposed surface. Carry monitors with you to measure different areas, or mount to your tripod to measure conditions over time.

To maintain their accuracy, monitors should be calibrated once a year. You can calibrate the monitor yourself using humidity standards. These standards contain a known humidity, so you can adjust your monitor until it reads the humidity correctly.

Monitors that come with a calibration certificate traceable to NIST have passed a test for accuracy.

Power these monitors with the included batteries, or add a power adapter to plug them in.

Add a memory card to store your readings and export them to a computer.
