More details

The Processor enhanced Detection (PhD) series of non- addressable detectors have been produced using the latest in manufacturing and design techniques, pushing out the boundaries of existing non-addressable detector technology. With an on board microprocessor, it’s multitude of enhanced features including drift compensation, provides the best in non- addressable detection.

Features

  • • Automatic drift compenstation
    • Programmable Sensitivity
    • Advanced maintenance features via remote hand-held test unit
    • Low profile design
    • Low current draw
    • Wide operating voltage 8 to 30VDC
    • Bi-colour LED detector status indicator
    • Addressable alarm location feature
    • Approved to EN54 part 7 (2000)
    • 3 Year warranty

‘Drift compensation’ algorithms are one of the key features of PhD series detectors. These algorithms ensure a consistent alarm sensitivity threshold for periods between service intervals. This provides the user with maintenance savings by extending the period before cleaning of the detector chamber is required whilst minimising the risk of nuisance alarms.

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. A detector’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

Installation

Each detector can be given a unique address. When used in conjunction with the S300ZDU Zone Display Unit the location of the alarm will be identified.
All the features via the hand-held programming unit are achieved effectively and effortlessly without the need to remove the detector or having to gain direct physical access (other than by the use of servicing poles in conjunction with the S300SAT), saving valuable commissioning/maintenance time.
