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.
