Heat Detector

DESCRIPTION

SHIELD Heat Detector monitors temperature by using a dual thermistor network which provides a voltage output proportional to the external air temperature. There are nine heat detectorsin the series range designed to suit a wide variety of operating conditions.

FEATURES

  • Can be used for applications where smoke detectors are unsuitable
  • Ideal environments that are dirty or smoky under normal conditions
  • Wide operating voltage
  • Flashing LED option
  • Flashing LED and magnet operated test switch option

Smoke Detector

DESCRIPTION

SHIELD Photo-Electric Smoke Detector incorporates a pulsing LED located within the housing of the detector. The detector housing is identical to that of the Ionization Detector but has an indicator LED which is clear in quiescent state but produces red light in alarm.

FEATURES

  • Responds well to slow-burning, smoldering fires
  • Well suited for bedrooms and escape routes
  • Unaffected by wind or atmospheric pressure
  • Wide operating voltage
  • Flashing LED option
  • Flashing LED and magnet operated test switch option

Control Panel

DESCRIPTION

Designed and manufactured to the highest standards in a quality controlled environment and with UL & FM approvals, the Shield A-XT releasing panel offers outstanding value and performance for all small to medium fixed firefighting installations.

With three detection zones as standard, extinguishant release can be configured to activate from any combination of detection zone inputs to allow ( among other combinations) any two from three type activations such as would be required for detection in ceiling void, room and floor void applications.

The extensive configuration options of the Shield A-XT allow the functionality of the system to be extensively modified.

The panel contains a large LED display to enable easy configuration and control which also displays the time remaining until extinguishant release for added user safety.

The countdown timer is duplicated on up to seven remote status units to provide local indication of the system status..

With all of the electronics mounted on a single, easily removable, steel plate Shield A-XT panels are both robust and easy to install..

Shield A-XT is supplied in an enclosure that matches the design and colour of the elite RS range and is available in standard red or optional grey
