1. Installation
The Premier 8XP expander is only compatible with the Premier range of control panels.
Expanders can be connected serially (daisy chain), in parallel (star) or any combination
of the two.
Mounting
Remove each screw cap by inserting a flat bladed screwdriver into the slot and turning
anti-clockwise, excessive force is NOT required. Remove both of the cover screws and
put them in a safe place along with the screw caps. Gently pull the cover away from the
base applying slight pressure to the sides at the top of the expander if required. The
front cover should now be off.
Mount the expander using at least two appropriate countersunk screws (no larger than
No. 8). A keyhole slot has been provided to assist mounting and aid levelling.
Wiring
It is strongly recommended that the system is completely powered down (mains and
battery) before wiring an expander. Connect the expander to the control panel using
4-core cable as follows:
Expander Control Panel Description
+ + +12V Supply
- - 0V Supply
T T Transmit Data
R R Receive Data
The networks are made up of four terminals incorporating power and data. To ensure
correct operation, all four terminals on the device must be connected to the
corresponding terminals on the control panel or previous device.
Expanders can be connected using 4-core cable. However, it is recommended that 6 or
8-core cable is used as the spare cores can be used to ‘Double Up’ on the power
connections if needed.
!"
Standard 7/0.2 alarm cable can be used for most installations. However, under
certain conditions it may be necessary to use screened cable.

Selecting an Address
Each expander must be assigned a different address using the DIL switches located in
the centre of the PCB. The table below shows the expander addressing:
Address DIL 1 DIL 2 DIL 3 DIL 4
1 On or Off Off Off Off
2 431
2 Off On Off Off
2 431
3 Off Off On Off
2 431
4 Off Off Off On
2 431
5 On Off Off On
2 4 3 1
6 Off On Off On
2 431
7 Off Off On On
2 4 3 1
8 On Off On On
2 4 3 1
!"
Never set two expanders on the same network to the same address.
Expanders are factory set to address 1.
