2.0 BASIC OPERATION
The Spectra 1689 LED and 1641 LCD Keypads function in
the same way, but display the visual feedback differently.
This section will provide an overview of the keypads.
Many of the features in your system must be enabled
by the installer. If the feature is not programmed, the
keypad will emit a rejection beep and the action will be
cancelled. Refer to “System Checklist” in section 8.0
for details.
