The HML/PSE photoelectric smoke detector forms part of the Honeywell Morley Lite range of addressable detectors. This range of detectors has been produced using the latest in manufacturing and design techniques, pushing out the boundaries of existing detector technology.
The HML/PSE photoelectric detector incorporates an Application Specific Integrated Circuit (ASIC). Combined with the latest state of the art optical chamber the detector provides efficient and accurate detection of fires with a high level of resilience to non-fireenvironmental influences.
The HML/PSE detector is backward compatible with the Series 100 detector bases, thus providing the capability to upgrade, extend and maintain existing Series 100 installations.
The HML/PSE detector incorporates a bi-colour LED indicator. The integral LED changes colour according to the detector’s status -Green = Normal, Red = Alarm. This benefits the user by providing clear, instant visual indication of the detector’s condition. The Green LED can be programmed for blink/no blink operation.
‘Drift compensation’ algorithms are one of the key features of the HML/PSE detector. These algorithms ensure a consistent alarm sensitivity threshold for periods between service intervals. This provides the user with both a reduction in the frequency of nuisance alarms and maintenance savings by extending the period before cleaning of the detector chamber is required.
The sensitivity of a smoke detector is critical to its overall performance, this is reflected in both its ability to detect real fire conditions and its resilience to non-fire stimuli. The HML/PSE’s performance can be optimised for it’s application by selecting from one of three preset alarm thresholds - Low, Medium and High, offering greater stability and optimum performance within the environment in which it has been installed. The selection is easily achieved through the use of a remote hand-held tool.
The remote hand-held programming unit can also be used to gain access to other advanced features. The features available include:read/write last maintenance date, read chamber contamination level, read value of thermal element and perform an alarm test.
