Trigger paging announcements, adjust volume, and initiate emergency calls wirelessly from anywhere in the room — the Viking BTR-3 is a compact wireless remote designed for the Viking 40TB-IP talk-back ceiling speaker, giving staff one-touch control without running back to a wall panel or phone. Up to four BTR-3 remotes can be paired to a single 40TB-IP speaker, giving multiple team members independent paging control from anywhere in the coverage area. The remote handles standard and emergency call triggering and paging volume adjustment. A CR2032 battery provides up to 3 years of normal use, and the battery is included so the unit is ready to use out of the box. Our Expert Take: The BTR-3 is a practical accessory for any space where the person making announcements isn't near a fixed paging station — retail floors, warehouses, gyms, and classrooms. Up to four per speaker means supervisors and staff across a zone can all have paging control without additional wiring.
