The Opal Base Sounder offers fast and simple installation, forming the ideal base for Notifier Opal detectors. Powered via the loop from the fire panel, the device can be controlled through on-board switches or using the Opal digital protocol from the control panel. Installation is quick and easy with a twist-fit onto the B501AP base.
Key Features:
Faster Installation: Large cable access, rear or surface entry options, and an innovative loop continuity spring make installation quicker and more cost-effective.
Reduced Installation Errors & Easy Fault Finding: Devices mount with a positive push-and-turn system, include an address tag for clear identification, and feature built-in isolation. Rotary wheel address controls simplify addressing, and an anti-tamper feature adds security.
Excellent System Performance: High light output and 32 selectable sounder tones can be synchronized via the Notifier control panel to provide fast, clear fire alerts.
Flexible Installation: Low current draw allows more devices per loop. Multiple mounting options—including deep and high IP bases, red or white color options, and panel- or device-controlled sounder volumes—offer maximum design flexibility.
Reduced Lifetime Costs: Constructed from UV-stable, impact-resistant materials, Opal AV devices are built for long-term reliability. The universal system base allows sounder or beacon units to be added without rewiring.
Reduced Inventory Count: The Opal AV range uses the common B501AP base, shared with detectors. It maximizes the features of Notifier’s advanced Opal protocol while remaining backward compatible for retrofit or replacement of older systems. Wall-mounted options include sounder-only, sounder & beacon, or beacon-only units in red or white, while integrated base units are available as sounder or sounder & beacon combinations matching detector colors.
