The LAMP TEST key on the operator interface panel is used to determine local lamp failures 
within the system.  Lamps on the operator interface panel illuminate along with the five function 
and acknowledge LEDs.   
 
The tone-alert (buzzer) can also be tested with the LAMP TEST.   
 
Do the following procedures to test for lamp failures. 
 
1.  Press the “LAMP TEST” push-button.  All LEDs should illuminate (lamps should stay 
illuminated as long as the key is depressed). 
 
2.  If you find defective lamps/LEDs, contact your local Simplex branch office. 
 
Holding the Lamp Test key for more than 3 seconds tests the tone-alert.
