The Sentry 1 channel learning receiver, also called the BTF receiver, works with Sentry 403MHz DIP switch remotes in binary, trinary and French codes. It learns one master code: set every remote to that code and they all open the gate. Change the code any time, and the old one stops working, which is handy when a remote goes missing.

Which remotes work with it?

Sentry 403MHz binary, trinary and French DIP switch remotes, such as the Sentry 1 button binary remote and the 3 button binary remote. Remotes copied onto a Sentry self-learning remote work too.

Wiring and settings

Connect 12 to 24V DC or 12 to 18V AC to POS and NEG. The 1 Amp potential-free relay has COM, NO and NC terminals, and a jumper chooses pulse or latch, so it suits gate motors, garage doors, alarms and electric fences. For magnetic locks, add an extra relay or relay board. Alectra Solutions supplies the receiver only.

How to tell it apart

Look for the yellow, red and black dot sticker on the carton and relay. The label shows firmware V3.3 and 403. Our quick guides in the photos cover connecting, adding remotes and fitting.

Questions people ask
What does BTF mean?

Binary, Trinary and French, the three Sentry 403MHz DIP switch code types this receiver learns.

How many remotes can it take?

It stores one master code, and every remote set to that code opens it.

A remote went missing. What now?

Program a new code into the receiver and set your remaining remotes to it. The old code stops working.

Will it work with Sentry code hopping remotes?

No. It learns binary, trinary and French DIP switch codes only.

Can it latch for an alarm or lights?

Yes. A jumper sets pulse or latch.

Will Alectra wire it in for me?

No. Alectra Solutions supplies the receiver only. You or your installer connect it using the quick guides.

Need it fitted? Alectra Solutions supplies product only. Ask the branch and we will point you to installers in Pretoria.
