RS485 bus wiring

Connect the expander to the control panel as shown in the wiring diagram.

LEDs

The green power LED will illuminate when power is applied to the expander.

Addressing the expander

Using a two pin jumper, address the expander as the next available expander on the RS485 bus. Once the jumpers are on the correct headers, press and hold the reset button for 5 seconds. Please see the table for help addressing the expander.

indicates that a jumper should be placed on this header

leave this header without a jumper on

Please note: Once the expander has been wired to the control panel and addressed, the expander will need to be programmed in to the system on the control panel. Please refer to the control panel guide.

Input wiring

The inputs must be wired DEOL or 3EOL between a 'COM' and a zone terminal. Please see diagram for an example of 3EOL wiring.

Please note: The resistors used are decided by the option selected in menu 'CHOOSE MODE' or 'WIRING CHOICE' in the control panel. Please see control panel guide for more details.

Inertia inputs

If any of the expander inputs are being used as inertia inputs, then the expander must be used in the 1k/1k resistance wiring range.

Fuse protection

Each 12VDC auxiliary output is protected by a 350mA PPTC fuse which should not be exceeded.

 

The fuse will trip when either the load surpasses the fuses maximum capacity or there is a short circuit. These fuses will reset when the issue that is causing the fuse to trip is reversed.

Expander tamper

An external tamper can be wired to the expander. This double pole circuit is wired between the 'COM' and 'T' terminals.

To disable the tamper, a two pin jumper is placed on the 'hold off' header.
