2.3.1  Clear Memory (0=CLR)
The Clear option removes all programming information from control panel 
memory. If installing the control panel for the first time, use option 0 to clear 
control panel memory. To do so, follow these steps:
1. From the “Basic Program” screen, press the 0 (zero) key to display the Clear Program screen. 
The control panel prompts for verification as shown below: 
2. Press the 
ENTER key to clear control panel memory or press the ESC key to exit the screen 
without clearing.
2.3.2  Autoprogram the Control Panel (1=AUTO)
Purpose
The Autoprogram option identifies all addressable devices connected to the control panel. Devices 
include addressable detectors and modules connected to SLC 1 or SLC 2, and NACs. You can use 
the Autoprogram option to create a new program and add or remove devices. A summary of the 
Autoprogram functions, when to use the functions, and where to find information on using the 
functions is found below:
