Apollo SA5500-551APO | Intelligent Open-Area Sounder VAD Cat. W (Red Body Red Flash W-3.1-9)

The Apollo Intelligent Open-Area Sounder VAD Cat. W (SA5500-551APO) with red body and red flash provides combined audible and visual alarm signalling for fire detection systems where a single alert method may not be sufficient.

Designed for use in noisy environments such as workshops, plant rooms and industrial spaces, the integrated sounder and visual alarm device also improves alarm awareness in areas where deaf or hearing-impaired occupants may be present.

The device offers a high level of configurability, with multiple selectable tone pairs and adjustable volume levels, allowing it to be tailored to suit site requirements and local standards.

Compliance with EN54-3 and EN54-23 ensures the unit meets recognised performance requirements for both sounders and visual alarm devices in fire alarm systems.

When used with an XPERT 8 base, the sounder includes a built-in controllable isolator to help maintain system integrity in the event of a short circuit fault.

Installation is straightforward on XPERT 7 or XPERT 8 bases, making it suitable for both new installations and system upgrades within addressable fire alarm systems from Apollo.
