The primary keypad must have the “zone termination” jumper removed. The primary “keypad
address” jumpers should both be removed.
The secondary “zone termination” jumper should be installed and the “keypad address” jumpers must
be set. JP1 should be removed. JP2 should be installed.
The distance between the MRCKPSP to the MRC88 Keypads is 500 feet maximum. The distance
between the MRCKPSP and the multi-room controller is less than 15 feet.
INTERNAL\EXTERNAL POWER
Using internal or external power on the MRCKPSP is determined by the application. The reason is
the Controller’s power capability may not be sufficient for certain applications, such as extended runs.
It is recommended to use an external power supply, such as the 782-00, in applications when more
than two keypads located 250 feet apart from the controller and an external device is used, such as
the WPK8 Waterpad, 380-20 Blast-IR, or 780-10 IR receiver.
- WARNING -
Do not connect a power supply to the MRCKPSP when the jumper is set to “INT”.
The Multi-Room Controller will be damaged!
