HML/PTSE

Honeywell ไฟอลาม Morley Lite HML/PTSE : อุปกรณ์ตรวจจับควัน/ความร้อนแบบโฟโตอิเล็กทริก Morley Addressable Multi Criteria Photoelectric Smoke/Thermal Detector


The HML/PTSE photoelectric smoke/thermal detector forms part of the HML Series 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/PTSE photoelectric smoke/thermal detector incorporates an optical chamber and a thermal element, which in turn are continually monitored by an on board processor by using algorithms
developed specifically for the unit. An alarm signal is only enabled in the detector once the processor is satisfied that an incipient fire has been detected. By using a combination of inputs, the incidence of
nuisance alarms is reduced while at the same time, the response time to an actual fire is also improved.

The HML/PTSE and other detectors in the HML Series range are backward compatible with the Series 100 detector bases, thus providing the capability to upgrade, extend and maintain existing Series 100 installations. The HML/PTSE 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/PTSE 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/PTSE’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 in conjunction with the HML Series range of detectors 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.
