The Viking Electronics BTR-3 is a wireless remote transmitter designed to work alongside the Viking Electronics entry phone line, specifically the K-1775-3 Series video entry phones with keypads and proximity card readers. Sold separately as an optional add-on, the BTR-3 gives personnel the ability to initiate both standard and emergency SIP calls and adjust speaker volume — without physically interacting with the entry phone panel itself. For lobby attendants, security desks, or warehouse receiving stations where the door panel is out of arm's reach, this kind of remote trigger capability is a real operational advantage.
The BTR-3 wirelessly initiates SIP calls — including emergency calls — and provides volume control for compatible Viking intercom and entry phone systems. This matters most in deployments where staff need to grant access or initiate communication from a fixed position (reception desk, guard station, loading dock office) rather than walking to the entry panel. The ability to trigger an emergency SIP call from a remote location is a meaningful capability for facilities where a panic-button equivalent needs to be discreet and portable.
The BTR-3 is documented as a companion device to the K-1775-3 Series entry phones — a platform that integrates a 125 kHz proximity card reader, a 420-line analog color video camera, and a stainless steel weatherproof enclosure. Understanding that context helps scope where the BTR-3 fits: it extends control of a hardened, feature-rich entry phone without adding wiring or modifying the panel installation. Integrators specifying a access control deployment around the K-1775-3 Series should evaluate whether staff workflows require remote call initiation — if so, the BTR-3 addresses that gap directly.
Note: detailed wireless specifications (frequency band, range, battery type, pairing procedure) for the BTR-3 (sometimes searched as BTR 3) are not available in current published evidence. Confirm compatibility and wireless range with Viking Electronics pre-sales before finalizing a design that depends on specific RF performance parameters.
Q: What entry phone models is the BTR-3 compatible with?
A: Based on available evidence, the BTR-3 is documented as a companion device to the Viking K-1775-3 Series video entry phones with keypads and proximity card readers. Confirm compatibility with other Viking entry phone series directly with Viking Electronics.
Q: What functions does the BTR-3 perform?
A: The BTR-3 wirelessly initiates standard SIP calls and emergency SIP calls, and provides remote volume control for compatible Viking entry phone systems.
Q: Is the BTR-3 included with the K-1775-3 Series entry phone?
A: No. The BTR-3 is sold separately as an optional accessory to the K-1775-3 Series.
Q: Where can I find the full BTR-3 installation manual?
A: Viking Electronics publishes product documentation on their official website. The K-1775-3 Series manual references the BTR-3 as a companion device and may include pairing and installation instructions.

The BTR-3 fills a specific gap in Viking K-1775-3 Series deployments: staff-initiated SIP calling — including emergency calls — from a location other than the entry panel itself. That emergency SIP call trigger is the spec worth paying attention to. In a guard-station or reception-desk layout, having a discreet wireless device that can fire an emergency call without requiring the operator to walk to the panel (or reach across a desk to a hardwired button) is a real design win. Whether the BTR-3 fits your project depends entirely on whether your workflow requires that kind of remote initiation.

Deployment Considerations:
Best fit: reception desks, guard stations, and loading dock offices where the K-1775-3 Series panel is mounted at the door but staff need to initiate or manage calls from a fixed interior position.
