HGD-AAB-A Amber Audible / Visual Hydrogen Alarm Beacon
The HGD-AAB-A is an amber colored remote visual and audible alarm beacon for and . While HGD detectors include integral buzzers, the HGD-AAB-A extends alarm coverage to remote locations and adds redundancy for critical spaces. It features 32 selectable tones, a 10-LED high-visibility strobe, and low power consumption so multiple strobes can be driven from a single HGD-5000 output.
- Remote visual + audible alarm for HGD hydrogen detection systems
- 32 selectable tones for site-standard signaling
- 10 high-density LEDs for high-visibility strobe
- Low power draw allows multiple strobes from one HGD-5000 output
- Compatible with HGD-5000 detector and HGD-5000-R repeater panel
- Activates at 2% H2 when triggered by HGD system
- Durable polycarbonate construction

What does the HGD-AAB add to an HGD system?
It extends alarm coverage with a remote visual strobe and audible signal, providing redundancy and alerting in areas away from the detector or panel.
Which HGD products is it compatible with?
It is designed for the detector and the .
How many beacons can I power?
The HGD-5000-R can power up to four (4) HGD-AAB beacons. The HGD-5000 provides a 12 VDC (504 mA max) strobe output—size loads accordingly.
When does the beacon activate?
When the HGD system detects hydrogen at its alarm threshold (2% by volume), it triggers the HGD-AAB-A to strobe and sound.
Is the HGD-AAB rated for outdoor use?
The beacon is for indoor use. For weather exposure, pair it with the HGD-AAB-WC weatherproof cover.
Can I select different sounds?
Yes, there are 32 selectable tones to align with site standards.
