The Fike Twinflex Multipoint ASD with Sounder (204-0001-B) is a plug-in multi-mode smoke and heat detector, finished in black, for the Fike Twinflex and TwinflexPro² 2-wire fire alarm systems. Twinflex devices share one pair of wires per zone, so detectors and sounders are installed on the same circuit, saving installation time and cost. One detector type suits almost every application, as the detection mode is simply set by switch at the time of commissioning.
Key features
- Integral 90dB(A) sounder with 3 selectable sound patterns (continuous 970Hz, alternating 800/970Hz, sweep 800-970Hz) and high/low volume
- Logical link option on TwinflexPro panels: during alarm confirmation, only the sounder in the device in alarm operates
- 7 detection modes selected by DIL switch at commissioning: Smoke 1 (standard optical, high thermal enhancement), Smoke 2 (standard optical, normal thermal enhancement), Smoke 3 (low sensitivity with transient rejection, for areas prone to nuisance alarms), Heat 1 (rate of rise, 58°C, Class A1), Heat 2 (fixed 58°C, Class A1), Heat 3 (high fixed 90°C, Class C) and combined Smoke 2 / Heat 2
- Photo-electric smoke sensing chamber plus thermistor heat sensing
- Built-in end-of-line signal, enabled by DIL switch on the last device (no resistor or capacitor needed)
- Head contamination warning before the detector becomes prone to false alarms
- Tamper-resistant locking: the head can only be removed with the Fike head removal tool
- Remote LED output (remote LED part no. 600-0092)
- Supplied complete with mounting base and dust cover
