Signal Path
A purely mechanical conversation between the entrance and the interior.
Air pulse
The press releases a measured pulse of pressure through dedicated tubing, no electric circuit closes, no contact is made.
Strobe Reveal
Indoors, a cover slides open to reveal a continuously strobing bulb, a clear, glanceable cue that someone is at the entrance.
Door Unlock
The resident presses unlock, pressure travels back to the entrance, the door unlocks, and the visitor sees a strobing bulb revealed at the entrance confirming they may enter.

Plan
Routing and equipment placement
Tubing paths, shafts, compressor location, ventilation, and service access are coordinated with the construction team.
Wire
Low-voltage indicator network
Indicator runs, controller placement, power, and network access are designed into the electrical scope early.
Fit
Custom fabricated hardware
CNC machined and 3D printed components solve exact site conditions, mounting geometry, and finish requirements.
Test
Commissioned on site
Signal travel, unlock delay, alert reset, shared circuits, and user operation are checked under real conditions.
Operation
Two sides of one system.
Visitor
- Press the entrance button for 2 seconds when the green indicator is on.
- Wait for the resident response.
- When a strobing bulb is revealed at the entrance, the door is unlocked, that’s your signal to enter.
Resident
Use the indoor buttons only when the strobing bulb is revealed inside.
- Release clears the indicator without unlocking the entrance.
- Unlock clears the indicator and unlocks the entrance for the visitor.
