Fike Sita Addressable Multipoint ASD Detector with Sounder / Strobe (205-0012)

The Fike Sita 205-0012 is an addressable multipoint ASD detector with built-in sounder and strobe, for Fike Duonet, Quadnet and CIE-A-200/400 addressable fire systems.

A photo-electric smoke chamber and thermistor heat sensor allow smoke, heat or combined detection, while the integral sounder and LED visual indication beacon give audible and visual warning from the same loop address.

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
• Built-in sounder with 7 sound patterns (SP1 to SP7) plus sounder off (SP0), and low, medium and high volume settings
• Soft addressed: addresses are allocated automatically by the control panel during initialisation
• Tamper-resistant locking mechanism; removed with the Fike head removal tool (25-0046-201) or keyring (23-0244-510)
• Remote LED output (Fike 600-0092) or auxiliary input/output via the Sita multipoint boxed auxiliary I/O module
• Base shorts loop +IN to +OUT until the head is fitted, for continuity testing
• Two-stage head contamination warning
• Visual indication beacon of high-output LEDs under a diffusing lens; it operates whenever the sounder is commanded, and can run on its own with sound pattern SP0
