Ritron RQA-151M VHF wireless call button key control

SKU CH-6YY1-HVQ6V

Wireless VHF call button in a sealed polycarbonate enclosure offers up to 7000 transmissions on six AA batteries

  • VHF MURS band reaches up to 1/4 mile
  • polycarbonate sealed enclosure resists weather and tampering
  • internal antenna keeps profile clean and snag-free
  • 7000 transmissions from six AA alkaline batteries
  • voice storage captures messages without external recorder

Purpose and user

The Ritron RQA-151M is a VHF MURS wireless call button built for access-control points where a simple push-to-talk alert is required. Its single-channel operation suits reception desks, loading bays or gatehouses that need a dedicated paging link without complex programming.

Build and daily use

A polycarbonate sealed enclosure protects the internal antenna and radio transmitter from dust and moisture in indoor or sheltered outdoor locations. Six AA alkaline cells housed in the included holder deliver up to 7000 transmissions before replacement, and the fixed 120 mW output keeps the unit licence-free on the MURS band.

Deciding specification

Voice storage capability lets the button record and replay a short message, a feature absent from basic alert-only models. Buyers who need multi-channel selection, external antenna ports or a display for channel feedback should look elsewhere.

Questions about this item

Does the VHF MURS band limit the RQA-151M to a specific output power?

The unit transmits at 120 mW on the VHF MURS band, which is the power level set for this call button.

What physical space is required to mount the sealed polycarbonate enclosure?

The enclosure measures 5 in wide, 7 3/5 in high and 2 1/10 in deep, so allow that footprint plus clearance for the button.

How do I install the six AA alkaline batteries and avoid the common mistake?

Open the sealed enclosure, insert six AA alkalines into the included holder observing polarity, then close the case; the step often missed is confirming the holder clicks fully into place before sealing.
