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.
