Fike Sita Addressable Multipoint ASD Detector (205-0003)

The Fike Sita Multipoint ASD (205-0003) is a plug-in addressable detector for the Fike Sita addressable system, compatible with Duonet, Quadnet and CIE-A-200/400 control panels. It combines a photo-electric smoke sensing chamber with a thermistor heat sensor, so the same device can be configured for smoke, heat or combined detection to suit almost any application.

Addresses are allocated automatically by the control panel during initialisation, so there are no address switches to set, and each device includes a built-in isolator. This version has no sounder; versions with a sounder (205-0001) or sounder/strobe (205-0012) are also available.

Key features

• Configurable smoke, heat or combined detection modes, set through the panel configuration software
• Smoke modes: highly thermally enhanced optical, thermally enhanced optical, and thermally enhanced optical with smoke pulse rejection
• Heat modes: rate of rise to 58°C, fixed 58°C, or high fixed 90°C
• Automatic addressing from the control panel; built-in isolator
• Self-calibrates every 6 hours and monitors for dust contamination, with two-stage head contamination warning
• Tamper-resistant locking - removal only with the head removal tool (25-0046-201) or keyring (23-0244-510)
• Remote LED output (for Fike 600-0092) or auxiliary I/O via the boxed interface (803-0005) - one or the other
• Spring arm in the base bridges Loop +IN and +OUT until the head is fitted, for continuity testing
