Twinflex ASD Detector with Optional Sounder in Black


SKU: 7e6936dc903d Category: Brand:


Fike Safety Technology has introduced a new detector for its popular TWINFLEXpro intelligent 2-wire fire alarm system. The Multipoint ASD detector has all of the features and benefits of the existing detector, including 7 modes of detection and optional built-in sounder, as well new features.

To ensure the detection capabilities of the detectors are never compromised they self-calibrate every 6 hours. They also continuously monitor for dust contamination until, depending on the environment, it reaches a point where the chamber becomes saturated. Before this can develop into a false alarm situation, the panel will indicate that the device in question requires attention.


The new Multipoint ASD detector range is available to order now with the following versions;

  • 204-0003-B – Twinflex Multipoint ASD Detector in Black
  • 204-0001-B – Twinflex Multipoint ASD Detector with Sounder in Black

Modes Of Detection

  • Smoke 1 – Used where ionisation detectors are normally fitted, especially when there are high ceilings or a risk of free burning fires (chemical stores etc.) or fires that need to be detected extremely quickly.
  • Smoke 2 – Used where optical detectors are normally fitted, when there is a risk of a smouldering fire and for escape routes.
  • Smoke 3 – Designed for use in areas that are prone to nuisance alarms. The reduced sensitivity linked with a time delay feature, means that a higher concentration of smoke needs to be present for a constant time period, before a fire decision is made. For example, this setting is ideal for hotel bedrooms with en-suite shower rooms. The installer or service engineer can change the setting from smoke 2 to smoke 3 if nuisance alarms are a problem whilst still offering optimum protection of a smoke detection setting.
  • Heat 1 (Rate of Rise) – Used where a standard rate of rise detector would normally be used.
  • Heat 2 (Standard Fixed Temperature – 58ºC approx.) – Used where a standard fixed temperature heat detector would normally be fitted, suitable for kitchens etc.
  • Heat 3 (High Fixed Temperature – 90ºC approx.) – Used where a high fixed temperature heat detector would normally be fitted. Suitable for commercial kitchens, boiler rooms etc.


  • Twinflex ASD detector in black plastic moulding
  • Available as detector only or with integral sounder
  • 6 selectable modes of detection


Does Fike recomend changing detectors after a period of 10 years?

Fike does not recommend that detectors over 10 years old should be changed. All detectors in the EN54 range produced by Fike Safety Technology include drift compensation, this enables the detector to maintain the sensitivity to alarm as contamination builds up within the head. Once the detector has reached the pre-set level and can no longer maintain the sensitivity a contamination fault is generated.

Is this Twinflex ASD detector compatible with the previous Twinflex V3 panels?

Yes all 3 versions of this detector are backwards compatable.
