Wiring 927 Keypads; Wiring Detector Zones - Scantronic 808 Installation And Programming Manual

3. Installation
Figure 6 shows the main connector on the 808 PCB. Subsequent sections
describe how to wire keypads, FSL and closed circuit zones.

Wiring 927 Keypads

All keypads must be connected to Keypad terminals on the main PCB or
"daisy chained" to other keypads. Figure 7 shows the connections for each
keypad:

Important: Please do not connect other devices (for example SAB, speakers and so
on) in the same cable as the remote keypad wiring.

Wiring Detector Zones

The 808 main connector has terminals for eight detector zones, as shown in
Figure 6. Zones can be wired as either two wire Fully Supervised Loop (FSL)
or four wire Closed Circuit (CC). However, all eight zones must be of the
same circuit type. The factory default is for CC zones. Use Menu 21 to
change between FSL or CC (see "4. Programming - Example 2").
