Panel features sunlight-readable annunciator

A new range of flight-deck security panels incorporate an integral sunlight-readable annunciator to ensure that flight crew are always able to see when the cockpit door is unlocked.

New from Paramount Panels (UK) is a range of flight-deck security panels that incorporate an integral sunlight-readable annunciator to ensure that flight crew are always able to see when the cockpit door is unlocked, regardless of the prevailing lighting conditions.

Designed as a front end for flight-deck access control systems in commercial aircraft, the new panel utilises high-brightness LEDs for illuminating the annunciator and conventional filament lamps for the rest of the panel legends.

The annunciator's "secret till lit" legend remains hidden until illuminated by the LEDs, and at night the panel's integral auto-dimming sensor reduces the light output from the LEDs to an appropriate level.

Because the annunciator is a critical function, the inherent reliability of the LED technology is augmented by the use of dual circuitry for built-in redundancy, thereby ensuring that the annunciator remains operational even in the unlikely event of an LED failure.

Manufactured for long life and reliability, the new flight-deck security panel is designed to meet the requirements of SAE AS7788 (formerly MIL-P-7788F).

The panel is supplied as a complete assembly - including switches and switchguards - and can be mounted directly on to a standard Dzus rail.
