Wiring Keypads

All keypads must be connected to Keypad terminals on the control unit PCB

or "daisy chained" to other keypads. Figure 3 shows the connections for each

keypad using the 9285 as an example:

recommended type is RS Components 349-254. A SEPARATE 12 Volt DC

supply is required. Contact rating is 10 A.

Caution: Do not connect other devices (for example SAB, speakers and so on) in the

same cable as the remote keypad wiring.
