The Pulsar 639T is a stationary wall-mount transmitter for commercial Open/Close/Stop radio control. It gives the user separate Open, Close, and Stop pushbutton functions through a compatible 318 MHz receiver instead of a simple one-button open/close command.
This transmitter belongs to a family of commercial Pulsar / Allstar style OCS stations. The key difference between models is the number of doors the station can address. The 639T is the 9 doors version, with a selector dial commonly labeled 1-9 for nine-door selection. That matters because a one-door, three-door, nine-door, and twenty-seven-door station are not the same part even though the button style and frequency may be similar.
Commonly associated with the following receiver families and commercial applications when frequency, coding, and door count match:

This is not a universal wall button. It is a radio transmitter for a matching commercial receiver. For replacement, match the old station model and receiver family first, then confirm whether the site needs 9 doors operation.
Commercial door and gate radio controls should be installed so open, close, and stop commands do not defeat monitored safety devices, entrapment protection, or required line-of-sight controls. If the operator wiring, voltage, or control inputs are uncertain, have a qualified gate or commercial door technician verify the installation.
Do not use an Open/Close/Stop radio station to bypass a required hardwired stop circuit or monitored safety device. The receiver output must be connected according to the operator control requirements.
The 639T version is intended for 9 doors when used with compatible 318 MHz Pulsar / Allstar style OCS receiver equipment.
No. It is a wall-mount radio transmitter that sends Open, Close, and Stop commands to a compatible receiver.
It is commonly associated with the Pulsar 831 receiver family and compatible Allstar / Allister 318 MHz Open/Close/Stop receiver systems.
Only if the door count and model number match. 831T, 733T, 639T, and 535T are related but different OCS transmitter layouts.
Confirm frequency, receiver family, door count, button function, and coding format. If the receiver is also being replaced, confirm voltage and wiring requirements.
