EX Signaling Device PRO10 3G/3D

766250 | EX Signaling Device PRO10 3G/3D

Robust explosion-proof audible alarm devices housed in a durable die-cast aluminium enclosure for use in demanding industrial environments.

Approved for Zone 2 (3G), Zone 22 (3D), and Class I / II / III Div. 2 hazardous areas. Optimized sound dispersion ensures excellent audibility, even in environments with obstacles and complex layouts.

Equipped with 80 integrated alarm tones and 3 additional externally selectable signals. The sound pressure level can be reduced by up to 30 dB, either internally or externally.

A pre-alarm and main alarm function enables staged alarm notification, helping to avoid startle reactions and improve personnel response.

Captive gasket and screws allow for fast and secure installation while reducing wiring effort and installation time.

Part-No.:
766250
Approval:
G 225036

Features

  • Universal sounder for indoor and outdoor applications
  • Exceptional durability – Die-cast aluminium enclosure (IP66/67) ensures a long service life in harsh environments
  • Explosion-proof – Suitable for use in hazardous areas classified as Zone 2 (3G) and Zone 22 (3D)
  • Excellent audibility – Optimized sound dispersion characteristics and outstanding penetration of acoustic obstacles reduce the number of devices required
