Installation and programming manual for the HAI Model 54A00-1 weatherproof piezoelectric Access Control Keypad.
Installation and programming manual for the HAI Model 54A00-1 Access Control Keypad — a weatherproof, vandal-resistant piezoelectric keypad for use with HAI automation controllers.
The Model 54A00-1 is a stainless-steel investment-cast keypad that interfaces with HAI automation controllers. Valid codes can arm/disarm the security system, activate an electric door strike or magnetic lock, control lighting, operate a garage door or security gate, trigger a panic alarm, and more. It mounts to a single-gang switchbox or directly to any indoor/outdoor wall surface. A red LED indicates the system is armed; a green LED indicates disarmed.
Requires one controller serial port and one programmable voltage output. Multiple keypads may be wired in parallel.

The piezoelectric buttons work by simply tapping the surface — no physical movement required, so they work equally well with a bare finger or a snow-covered glove. Each key press emits a short tone and flashes the red LED.
When connected to an HAI security system: red LED = armed (Away/Day/Night/Vacation, etc.); green LED = disarmed (Off mode). On a Lumina or Lumina Pro, or for a custom function, the LED can be controlled programmatically by toggling the corresponding voltage output on/off.
Using code 1234 to toggle between Away and Off:
WHEN ARM AWAY: Armed Flag ON WHEN OFF: Armed Flag OFF WHEN RECEIVE 1234 &IF Armed Flag OFF: PROGRAM ARM AWAY WHEN RECEIVE 1234 &IF Armed Flag ON: PROGRAM DISARM
Every "1 2 3 4 #" entry toggles the system between Away and Off, with red/green LEDs toggling accordingly.
Using code 12341 to release a strike wired to Output 2, with Output 1 (green LED) showing lock state:
WHEN RECEIVE 12341: Door Strike ON FOR 5 SECONDS WHEN Door Strike ON: Red LED ON WHEN Door Strike OFF: Red LED OFF
Every "1 2 3 4 1 #" entry disengages the door strike for 5 seconds; red LED = unlocked, green LED = locked.
