Sentry 1 Button Binary 403MHz Remote Transmitter

R 178.25

This is a standard dip-switch type remote control that features up to 4096 unique codes in the binary transmission operating in the 403MHz range.

This transmitter is configurable to operate as a standard remote control or in "split code" mode of operation for townhouse complexes where a given transmitter may be used to control multiple devices such as gates and garage doors, alarm systems and the like. 

These transmitters also feature a split-code mode which is very useful for use in townhouse complexes where a common code may be set for the gate but still allowing the owner or tenant to have up to two user-unique buttons to control the individual garage doors.
