Pulsar 831T 318 MHz Wall Mount Open/Close/Stop Transmitter for 1 Door
The Pulsar 831T 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 831T is the 1 door version, with no multi-door selector on the basic one-door station. 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.

Technician Note
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 1 door operation.
Before Ordering
- Confirm the existing receiver operates at 318 MHz
- Confirm the system uses separate Open, Close, and Stop commands
- Confirm the number of doors controlled by the old transmitter
- Match the dip-switch or trinary coding format
- Verify receiver voltage separately if the receiver is being replaced too
Professional Advisory
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.
Important Ordering Warnings
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.
