Expanders for intruder alarm systems

All security systems have a small number of terminals on the main security board, usually ten. Using an expander lets the system unlock additional zones, with a choice of hardwired or radio. Alarm installers can keep adding expanders up to the limit set in system programming.

Our expanders reduce the maintenance time required with a device locate feature that utilises an onboard piezo sounder. The EXP range also benefits from full diagnostics and fault reporting via the data bus.

Both wired and radio options available
i-onEX range, i-on30R and i-on40H

Simple to install

All Expanders have one-push for semi-auto addressing ensuring a unique device address. This eliminates counting errors and there are no links to lose and speeding up installation.

Wireless security expanders

The EXP-R10 and EXP-R30 are designed for Grade 2 installation. These wireless expanders can also provide wireless radio hold up alarm (HUA) functionality in Grade 3 installations.
