Designed for fast and simple installation, the Opal base sounder provides an ideal foundation for Notifier Opal detectors. Powered via the loop from the fire panel, the device can be controlled using on-board switches or through the Opal digital protocol via the control panel. Installation is straightforward with a simple twist-fit onto the B501AP base.
Key Features
Faster Installation – Large cable access, rear or surface entry options, and innovative loop continuity springs make installation quicker and more cost-effective.
Reduced Installation Errors and Easy Fault Finding – Devices engage with a positive push-and-turn system and include address tags for clear identification. Built-in isolation and rotary wheel address controls simplify setup, while an anti-tamper feature enhances security.
Excellent System Performance – High light output and a choice of 32 synchronised sounder tones via the Notifier control panel provide fast, clear fire warnings.
Flexible Installation – Low current draw allows more devices per loop. A wide range of mounting options—including deep and high IP versions, red or white units, and adjustable sounder volume—offers maximum flexibility for system design.
Reduced Lifetime Costs – Constructed from high-quality, UV-stable, impact-resistant materials for long-term reliability. The universal system base allows sounders or beacons to be added without re-wiring.
Reduced Inventory Requirements – The B501AP system base is compatible with all Opal AV devices, including retrofit and replacement for older Notifier systems. The Opal AV range includes wall-mounted sounders, sounder & beacon combinations, and beacons only, as well as integrated base sounders available in matching red or white to complement Notifier detectors.
