|The 700 series of detectors are microprocessor-based conventional fire detectors. There are five models in the range, which measure certain parameters and respond to them. The parameters monitored are:
The 700 series of detectors are used for conventional 2-wire detection systems, where detectors will normally be connected in zones. Each detector samples the ambient air every 5 seconds. If a fire condition is detected, a signalling current is drawn.
These intelligent, conventional detectors come with built-in drift compensation (P and PH variants only). Once the drift compensation limit has been reached, i.e. the detector has become too dirty to operate at the same sensitivity, the detector will automatically adjust the sensitivity to allow it to continue operating. This feature will extend the life expectancy of the detector.
Another feature of the 700 series detectors as a result of the built-in microprocessor is the improved detection algorithms. These are equivalent to non-Fastlogic in our Gen6 detectors and offer the same detection performance and false alarm rejection.
The PH detector is approved to EN54-29, a multi-sensor standard for smoke and heat. This is the first conventional detector from JCI to be approved to this non-harmonised standard.
The 701P smoke detector operates by sensing the optical scatter from smoke particles generated in a fire. The micro-processor inside the detector allows for threshold compensation, meaning the detector will adjust sensitivity levels to compensate for dust and dirt levels in the chamber, resulting in fewer unwanted alarms and an extended detector life.
The 701PH optical and heat detector operates by sensing the optical scatter from smoke particles generated in a fire, and a rapid rate of rising temperature increases the smoke detection sensitivity for normal ambient conditions, the high performance optical detector behaves as a normal optical detector. The 701PH is approved to EN54-29, a multi-sensor standard for smoke and heat.
70x-H Series heat detectors includes rate-of-rise and 60°C and 90°C fixed temperature types. These detect abnormally high rates of rising temperature and high temperatures of 60°C and 90°C, respectively.
