The EXT-AS-HS-BLU is a combination external horn and strobe alarm for Belimo 22G gas monitor systems — a 94 mm cubic multi-tone sounder paired with a high-power LED strobe beacon in a blue lens. It provides loud, highly-visible alarm signalling in large or high-ambient-noise spaces where the monitor's on-board horn alone is insufficient.
Extends audible/visual alarm for any Belimo 22G gas monitor: 22G02-5A, 22G02-5B, 22G02-5C, 22G14-5A, 22G14-5B, 22G14-5C, 22G0214-5A, 22G0214-5B, 22G0214-5C, 22G15-5A3, 22G15-5A5, 22G15-5B3, 22G15-5B5, 22G15-5B6, 22G15-5C6, 22G21-5C.
Large parking structures, warehouses, and mechanical rooms with high ambient noise or long sightlines, where a remote high-output horn/strobe ensures the alarm is heard and seen throughout the space.
Key Features
Combines a multi-tone sounder up to 108 dB(A) with a high-power LED strobe beacon for alarm coverage in large or high-noise spaces beyond the monitor's on-board horn.
