On a Honeywell Vista panel, CA (or, on alpha keypads, “Alarm Canceled”) indicates an Exit Alarm was triggered but then canceled before the entry delay timer expired
Exit Delay: After arming (Stay/Away), you're given time to leave before the system fully arms.
Exit Fault: If a door or interior zone remains open when the exit delay ends, the system starts sounding an alarm and initiates an entry delay
Canceling the Alarm: If you disarm the system during the entry delay, the alarm stops and the display shows CA—but importantly, no alarm signal is sent to the central station
To clear this message and restore normal operation:
Close any open zones: Make sure all doors and interior zones are securely closed (or bypassed if intentional).
Acknowledge the screen:
Enter your 4-digit security code, then press OFF (or the [1] key on fixed-word keypads) once. The alarm beeps will stop.
If CA remains, re-enter your code + OFF again to fully clear the display.
Re-arm as usual: Once cleared, you can arm the panel (AWAY, STAY, INSTANT, etc.) normally.
Ensure exit zones are closed before arming: Don’t arm if an entry/exit door or interior zone used during exit is open.
Allow full exit delay time: Let the panel complete its countdown before using that zone.
Bypass zones if needed: If you need to leave a door open, bypass it (Code + 6 + zone number) before arming.
Confirm with READY: Press * to review open zones before arming—when READY is displayed, it’s safe to arm.
If you continue to see CA even after all zones are closed and clearing with your code, or if you experience repeated exit/alarm issues, it may signal a sensor or wiring fault. In that case, contact your installer or alarm service provider for further diagnosis.
