Press the star sign ∗ to abort an unwanted entry to prevent it from being saved and to revert
back to the last display code viewed. To discontinue the entry procedure, press the star sign

STARTUP PROCEDURES:
To bring the Series 8900SH Control Panel online, the following three steps must be
completed:
1. Unlock the keypad using code 61. (See Section 8)
2. Enter the code settings through the keypad. (See sections 3 and 8.)
3. Calibrate the sensors. (See Section 4).
System shut down and start-up should be done through the keypad only, (by using Code
62) and NOT by shutting off power to the control panel. If the power to the panel is off for
more than 30 days, all control settings will be lost. In the event of temporary power loss the
panel has two built-in rechargeable batteries that will maintain the settings for up to 30
days. THE FIRST TIME THE PANEL IS TURNED ON THE BATTERIES WILL REQUIRE 48
HOURS TO TRICKLE CHARGE.
Code 61 is used to lock or unlock the system. Lock the system when you are completed
with the initial settings, or any time you change the settings. The system display readings
are always available, even with the keypad locked.
