Detectors

A detector is selected based on the goal of earliest and safest detection possible.
A detector is selected based on the goal of earliest and safest detection possible.

When choosing a detector, the following criteria is important:

  • What is to be detected (smoke / heat / flame / gas)
  • Type of fire / fire development
  • Environment / surroundings
  • Location
  • Coverage area
  • Acceptable degree of nuisance alarms.

KEY POINTS IN NORWEGIAN NORMS

Local regulations will apply

Naturally, the rules concerning fire detection are many and elaborate. Here are some golden rules:

  • Detectors should not be placed closer to a wall than 0.5 m.
  • If circumstances permit it, detectors should be placed at least 1 meter away from air-conditioning inlets or ventilation.
  • Stairwells should always be equipped with detectors on the top floor. Additionally, there should be detectors on at least every third floor.

For details, see the Norwegian Standard NS 3960: 2013 Fire alarm systems design, installation, operation and maintenance.

All our detectors are equipped with DYFI+ filters providing better and faster detection with fewer unwanted alarms. 

  • The transient filter recognizes phenomena not related to a real fire, such as steam and cigarette smoke.
  • The pollution filter automatically and individually maintains the chosen sensitivity during the entire life cycle of the detector.
  • The smouldering filter provides accurate and rapid detection in the event of smouldering fires.

AutroGuard® multicriteria protectors

AutroGuard® multicriteria protector provides a new generation technology that simplifies installation and commissioning, and increases fire safety. It is more than a detector, it is a PROTECTOR. It detects fire and gives warning – all in the same device.
