The ―LAMP TEST‖ push-button on the operator interface is used to determine local lamp
(LED) failures within the system. LEDs on the 4100ES-S1 operator interface and
Switch/LED Display Modules illuminate. All segments on the LCD also change to squares.
Perform the following procedure to determine LED or LCD failures.
1. Press the ―LAMP TEST‖ push-button. All LEDs should illuminate (LEDs should stay
illuminated as long as the push-button is depressed). Holding the push-button in for more
than 3 seconds will test the buzzer.
2. Perform an individual lamp test on all remote LCD annunciators using the key switch on
the remote annunciator.
3. If you find defective lamps/LEDs, contact your local Tyco Service provider.
