Heat Detectors

Heat detectors are one of several initiating devices found within fire alarm systems. They are an essential part of any automated fire suppression system. This is especially true when monitoring areas of a facility where heat rise may precede any detectable level of smoke. 

Heat detectors come in rate-of-rise or fixed-temperature models. Rate-of-rise heat detectors measure a specific change (increase) in temperature in a given timeframe whereas fixed-temperature models activate when a specific temperature is detected. 

Heat detectors operate 24 hours a day, seven days a week, to protect facilities and equipment.  In some cases, fires can occur with little evidence except for a measurable heat rise in the vicinity of the fire.  Heat detectors, paired with smoke detectors, offer protection over a wide range of conditions and situations.  Herbert Williams also offers accessories and maintenance supplies for your heat detectors.
