Nittan launches visual alarm base for photoelectric smoke detector

by Featured NewsFire DetectionProducts

Nittan Europe, a manufacturer of fire detection products sold globally, has launched the EV-PYSVAD Visual Alarm Base for use with its EV-PYS Photoelectric smoke detector.

The new EV-PYSVAD is a Type A Indoor Beacon Base VAD with enhanced performance. It features 12 high power white LEDs which provide the required light output to meet the EN 54-23 Category C (Ceiling) certification requirements with a rating of C 3.0 x 5.0. As a slave device taking its commands from the EV-PYS detector, the EV-PYSVAD does not require an individual loop address.

The EV-PYSVAD has been designed to be a backward compatible drop-in replacement for its predecessor, the EV-PSBCN Visual Indicator Base, without the need for panel upgrades or type code changes.

The EV-PYSVAD Visual Alarm Base has been introduced specifically for use with Nittan’s EV-PYS Photoelectric smoke detector, which comes with a sounder.

The EV-PYS features an advanced smoke sensing chamber designed for maximum effectiveness. A spherical feature incorporated within the chamber provides superior light scattering, plus an orange LED is used, which significantly improves response across the fire spectrum.

The shape of the ‘PY’ smoke chamber is optimised to minimise the effect of dirt/dust contamination, plus a fine stainless-steel micromesh prevents the ingress of even the smallest insects which can create false alarms.

Nightingale Hospital Bristol installs Nittan fire detectors

by Featured NewsProducts

Built in less than three weeks at the University of West of England Frenchay Campus, Nittan Europe is proud to have its Evolution analogue addressable fire detectors installed into the recently opened NHS Nightingale Hospital Bristol.

Having the capacity to provide up to 300 intensive care beds for coronavirus patients, if local services need them, the new facility is one of seven Nightingale hospitals to be set up around the country as part of a massive NHS effort to respond to the COVID-19 health emergency.

The Nittan fire detectors have been incorporated into Ramtech Electronics’WES wireless firm alarm system, which is designed to provide a simple, fast and secure method of communicating fire and medical emergencies in the complex environmental conditions of construction sites.

Whilst WES has been designed to provide temporary protection on construction sites, its ease of use, reliability and quality made it ideal for use in the temporary Nightingale Hospital.

Wireless fire alarm systems are ideal for temporary sites as they don’t require specialist trades to set up, and any number of call points can be deployed in minutes and linked wirelessly to cover large or small sites. The signal passes through all commonly found materials including steel, concrete and stone.

Nittan Evolution EVC-DP dual optical detectors are incorporated into the WES system.  These award-winning detectors feature dual optical technology to reduce false alarms caused by non-combustion products such as steam, dust and aerosols.

According to the manufacturer, the EVC-DP effectively measures the actual particle size in the chamber via its combined IR and blue LED technology. As steam and dust are much larger particles than smoke, the detector won’t false alarm. This makes the EVC-DP detector ideally suited to use in hospitals, hotels and other areas of multiple occupancy which are prone to steam and dust.

The WES wireless fire alarm system, featuring the Nittan detectors, has also been installed into the communal and welfare areas of NHS Nightingale Hospital Bristol.
