Keypad Installation
Wiring Specifications
Connect the additional keypads either using a STAR or MULTIDROP configuration.
MULTIDROP the keypads are 'daisy chained' together, each keypad being connected in parallel
to the one before it.
STAR each keypad is wired back separately to the control panel terminals.
Any combination of the above wiring methods is allowed with the restriction that the total cable length
on each of the wiring loops (either multidrop or star) is restricted to 100m.
The following diagram shows how 4 RKPs may be connected using both methods.
