Honeywell HEX-24 Intevio 24-Zone Expander

The Honeywell HEX-24 Zone Expander adds 24 speaker zones and 24 monitored contact inputs to the Intevio system. It can connect with up to 6 external power amplifiers and 1 backup amplifier. The contact inputs can be linked with a fire alarm system to trigger alert and evacuation messages in case of a fire. One line input can connect with an external audio source, which can function even if the controller CPU malfunctions. This advantage reduces system downtime and increases safety during emergencies.

Honeywell’s HEX-24 Zone Expander has a powerful automatic fault diagnosis function to supervise various types of faults such as main power, backup power, CPU, power amplifier, speaker circuits, and communication line. All the fault information will be shown on the LED indicators on the front panel. 

Moreover, the external audio source connected to the line input can still be delivered to all the local zones even when the controller CPU malfunctions. This function can reduce system downtime due to CPU failure and increase safety during emergencies.
