Nfpa 72 chapter 5 initiating devices heat detectors.
Rate of rise heat detector attic.
The series 600 heat detector is attractive durable and features combination rate of rise and fixed temperature operation.
The rate of rise sensor detects a rapid rise in temperature and signals an alarm if the rise is 15 f 8 c or more per minute.
Alarm is audible up to a distance of 10 ft.
Under normal ambient conditions with an air velocity at the detector of 400 feet per minute or less the detector s contacts should close within 10 seconds when the heat gun nozzle is located approximately 6 inches from the detector.
Features alarm latch to easily identify initiating alarm.
Rate of rise heat detector is a wireless device used with alarm systems that support honeywell s 5800 series devices.
The pneumatic element responds to a rapid rise in temperature approximately 15ºf 8ºc per minute when the air expands faster within the sealed chamber than it can escape through the calibrated vent.
The kidde hd135 f is inter connectable.
The interconnect system must not exceed the nfpa national fire protection association limit of 18 initiating devices smoke heat co etc interconnected it is still possible to interconnect 6 strobe lights and or relay modules.
The 120 volt hardwired heat alarm detects heat at 135 f with its microprocessor temperature sensor.
The usual approach is to install rate of rise heat sensors in the attic.
They are not life safety devices though.
The 5809ss combines a rate of rise sensor and a fixed temperature sensor in one device.
The rate of rise test should be conducted by a qualified fire protection specialist using a 1 000 watt heat gun or hair dryer.
Btw there is one system sensor brand we sell online smoke detector that is designed for dusty environments.
The 5809 series is ul listed ul 521 and csfm approved for commercial and residential applications.
This is a continuation on the series of articles about the most important requirements in nfpa 72 national fire alarm code book.
The alarm will sound if temperatures rise above 135 f.
The 5809ss rate of rise thermostat senses the rise in temperature and signals an alarm if the increase is 15 f or more per minute.
The rate of rise function detects heat quickly by responding to a rapid temperature increase.
Treated with the powerful rate of rise and fixed rate technology.
Rate of rise thermal detectors measure the rate at which the air temperature changes during a fire event.
Rate of rise detects heat by quickly responding to a rapid temperature increase.
Heat detectors are available in 135 f and 200 f temperature ratings.
