LED lamp and/or a small buzzer to notify a guard, to energize a relay to switch on lights or a CCTV camera...
• Make sure that the relay for switching on the lights has enough isolation between the high-voltage and low-
voltage to prevent damage to the keypad.

rating of 100mA.
• External power supply and isolation relay are necessary for driving high-power devices such as lights.
