The sleeved casing allowing the main damper assembly to be fully recessed, with internal surfaces painted black allowing them to be hidden by the easy-fit grille.

EV-301 Smoke Ventilation AOV Control Panel with Battery Back-up

The CE-marked for smoke control use (tested to EN 12101), control panel monitors and controls smoke control ventilators and interface devices all with the added security of a battery back-up.  The innovative design provides a programmable facility (via DIP switches) for limited ventilation (used on day-to-day ventilation to prevent AOV windows opening fully) and timed openings used in conjunction with a thermostat for corridor cooling.

Maintenance Switch

Tamper-proof switch for testing and monitoring smoke control systems with a visual and audible indication in accordance with BS EN 12101 Part 9 and BS ISO 21927 Part 9.  Two buttons provide override open, close and reset functions and three coloured LEDs with an audible buzzer indicate system health, fault and alarm status.

Photoelectric Smoke Detector

The Easivent photoelectric smoke detector uses a state-of-the-art optical chamber combined with an application-specific integrated circuit to provide quick and accurate detection of fires. The detector has an integral LED, which illuminates to provide a local alarm signal. This latches on and remains illuminated until the detector is reset by a momentary power interruption.
