Keypad Key Alarm

What does A-17 mean?

An alarm indicating a problem with the keypad's physical keys. This can be triggered by a key being held down continuously for too long, a disconnected membrane switch, or a key being pressed during keypad power-up.

• A physical key on the keypad is stuck in the pressed position due to debris, mechanical failure, or membrane damage.
• Internal keypad membrane switch damage causing continuous electrical contact for one or more keys.
• Keypad mounting issue, causing external pressure to be continuously applied to a key (e.g., enclosure too tight).
• Keypad firmware glitch or internal electronics issue intermittently detecting a pressed key.
