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.

Performance and installation

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.

For maximum flexibility and ease of installation, 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.

Features of EV-PYSVAD

Fine stainless steel micromesh prevents the ingress of even the smallest insects which can create false alarms

The EV-PYSVAD Visual Alarm Base has been introduced specifically for use with Nittan’s EV-PYS Photoelectric smoke detector, which comes complete with an integral 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 optimized to minimize the effect of dirt/dust contamination, plus fine stainless steel micromesh prevents the ingress of even the smallest insects which can create false alarms.

Addressable fire detection range

The EV-PYSVAD Visual Alarm Base is the latest addition to Nittan’s Evolution analog addressable fire detection system range.

The Nittan Group has been at the forefront of the international fire protection industry since 1954. It continuously innovates and strives for exceptional quality products of the highest standards.
