Nittan Evolution PY Addressable Optical Smoke Detector with Short Circuit Isolator
£23.53 (inc VAT: £28.24)
Summary
The Nittan EV-PY-SCI is an optical smoke detector with integral short circuit isolator compatible with Evolution analogue addressable system devices.
The Nittan UB-6-SL-EV Base includes a sliding link, to provide loop continuity, when detectors are removed. This is to ensure Call Point operation is not affected by head removal, in accordance with BS 5839-1, Clause 12.2.2.
Device address may be set using the Nittan EV- AD2-EXT Hand held programmer.
The Short Circuit Isolator is bi-directional and will protect the system, whilst allowing the device to continue communication from the opposite side. The isolator will self-reset when the fault is cleared.
Features
- Integral -ve short circuit isolator
- Improvements to smoke sensing chamber
- Orange LED, which significantly improves response across the fire spectrum
- Chamber construction is also designed to minimise the effect of dirt/dust contamination
