Fike Sita Addressable Multipoint ASD Detector (No Base) (205-0003-NB)

The Fike Sita 205-0003-NB is the Sita addressable multipoint ASD detector head, supplied without a mounting base, for Fike Duonet, Quadnet and CIE-A-200/400 addressable fire systems.

A photo-electric smoke chamber and thermistor heat sensor let one device be set for smoke, heat or combined detection. It fits the Sita multipoint detector base, which is supplied separately.

Key features

• Photo-electric smoke chamber plus thermistor heat sensing, configurable for smoke, heat or combined detection
• Smoke modes SM1 to SM3 (thermally enhanced optical) and heat modes HM1 (rate of rise to 58°C), HM2 (fixed 58°C) and HM3 (fixed 90°C), set from the panel or OSP software
• Soft addressed: addresses are allocated automatically by the control panel during initialisation
• Tamper-resistant locking; head removed with the Fike head removal tool (25-0046-201) or keyring (23-0244-510)
