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.
