Dimensions and weight
Please see diagram for dimensions and weight of product.
RS485 bus wiring
Connect the expander to the control panel as shown in the wiring diagram.
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.
Expander tamper
An external tamper can be wired to the expander. This double pole circuit is wired between
the 'COM' and 'T' terminals. If the two pin header labelled ‘HOLD OFF’ is linked out, this bypasses
the external tamper, overrides it and keeps the tamper circuit closed.
LEDs
The green power LED will illuminate when power is applied to the expander.
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. For this option and assistance on
zone wiring, please see control panel guides 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 rectified.
