Baldwin Boxall OCBARG OmniCALL Type B Advanced Refuge Outstation | Two-Way Speech, BS 5839-9

No local power supply is needed, as the OCBARG is powered directly from the OmniCALL loop or radial circuit. Battery backup and standby duration are provided at the master station/panel level rather than at the outstation itself, so check the OmniCALL master station documentation for the specific standby time achieved on your system.

Yes. It’s surface mounted as standard but can be flush mounted using the OCBARG-BZ bezel. Check the bezel cutout dimensions against your wall preparation before first fix.

Yes, the OCBARG can be wired on the same loop as other OmniCALL outstations or connected via a radial from the control panel. An optional link between the OmniCALL console and the fire detection system can also be configured to help prevent hoax disabled refuge calls; this forms part of the wider system design, so refer to the manufacturer’s installation documentation for wiring details.

It’s designed to meet BS 5839-9:2021 and BS 8893:2024, which cover emergency voice communication systems including disabled refuge points. Wider requirements such as BS 9999 and Building Regulations relate to the overall fire strategy and evacuation provisions for the building, so these should be confirmed with the building’s fire risk assessment or building control rather than from this outstation’s datasheet alone.

The datasheet doesn’t specify a maximum cable run length or a mandated cable type for the loop or radial wiring. Cable specification and permitted run lengths depend on the overall OmniCALL system design, so confirm these details with Baldwin Boxall’s installation documentation or technical support before finalising the containment design.

Yes, the OCBARG includes a built-in induction loop for hearing aid users at the refuge point, in line with the accessibility requirements for disabled refuge outstations.
