Overview

The ViAC-ACA-W provides a simple solution to integrating emergency assist alarm call systems within an EVCS, providing a single display point for all disabled calls within a building. It can be used on a dedicated line, or may share a line with the ViLX-OSB disabled refuge outstation (as long as fire rated cable is used), where operation of the refuge point overrides the assistance call (ideal where a disabled toilet is adjacent to a refuge lobby). The ViAC-ACA-W kit is also compatible with the ViAC-4ZC-W four zone control module and Assist Call Network System for applications without EVCS

Operation

When a pull cord is activated, the over-door indicator and cancel plates emit an alternating tone with flashing blue indication. After system acknowledgment the over-door and cancel Indicators change from flashing to steady illumination, with a double beep tone every 15 seconds. This reassures the occupant that help is on the way, instruction signage is provided Within the kit.

Additional features

The Assist Call range of integrated emergency assistance alarms have several advantages over other self contained units. As follows:

• No local mains PSU at the WC
• All field wiring is monitored
• Central indication
• Acknowledge feature as per BS 8300-2:2018
