Many states or local municipalities require gas stations to provide customers with a way to reach an attendant from the pump. This MURS wireless intercom kit provides that connection in minutes—no trenching, no electrician, and no FCC license required. Support one pump with a standalone system or connect two pumps to a single callbox. Need to expand? Additional pumps can easily be added as your station grows.
Call 888-298-9489 — we'll help make sure you get every component right the first time.
Each callbox runs on the MURS radio band, which the FCC lets anyone use license-free. Out of the box, one callbox talks to one handheld radio or base station — plug-and-play, no configuration needed. If you're running more than a couple of callboxes, our RT1146 handheld radio can be programmed with privacy codes so each callbox only responds to its intended radio, letting you run up to 16 callboxes across the 5 available MURS frequencies without them talking over each other.
Most single- or two-pump installs never need to touch this configuration. It matters most for larger stations running several callboxes at once — see the technical detail below if that's you.
The outdoor callboxes use MURS (Multi-Use Radio Service) frequencies, which are FCC-license-free. MURS provides 5 base frequencies; adding CTCSS (Continuous Tone-Coded Squelch System) privacy codes expands this to 16 distinct channels on our RT1146 handheld radio, so devices can be configured to respond only to their intended traffic and reduce interference between callboxes.
CTCSS codes provide selective communication, but two callboxes transmitting at the exact same moment on the same frequency can still interfere with each other. We can help you plan a channel layout for larger multi-pump installs.
A growing number of states, or even local municipalities, require gas stations to provide a working method for customers to reach an attendant from the pump island. This kit is designed specifically to satisfy that requirement wherever running conduit or wiring to each pump isn't practical — check your state's specific fire marshal or weights-and-measures regulations for the exact wording that applies to your location.
A: Yes, as long as the fuel pump provides 12 volts DC. You'll need the optional RT1097 power adapter cable.
A: No. To conserve battery power, the callbox stays in sleep mode until a customer presses the button, which wakes it up and enables two-way communication.
A: Check the Related Items section below for the individual callbox unit. You can add as many as you need — as long as they're all set to the same channel, there's no limit.
A: Yes. Multiple outdoor units can call into multiple indoor units. If the system is mainly for customers calling in, each outdoor unit can be set to auto-turnoff mode so it sleeps when idle. All units would share the same frequency, and only the calling intercom's conversation is heard. Alternatively, you can program up to 5 units on separate channels for independent calling, and by adding privacy codes to those 5 channels, the system can support up to 16 pumps.
