FAQ

What standards does the ViAC-ACA-W comply with?

The ViAC-ACA-W is fully compliant with BS8300-2:2018 for accessible toilet requirements and BS5839-9:2021 for emergency voice communication systems. It also meets EMC standards EN 55035:2017+A11:2020 and EN 55032:2015+A1:2020, plus LVD standard EN IEC62368-1:2020 + A11:2020.

Do I need a local power supply unit at the toilet location?

No, one of the key advantages of the ViAC-ACA-W system is that no local mains PSU is required at the WC location. Power is supplied through the monitored field wiring from the central control panel.

What type of back-box do I need for installation?

The system can be used with any “MK” style single back-box over 25mm deep. For cable glands, the back box needs to be 35mm deep. This includes metal clad surface types and plastic plasterboard liner boxes. Back-boxes are not supplied with the kit.

Can the ViAC-ACA-W share a line with other systems?

Yes, it can share a line with the ViLX-OSB disabled refuge outstation, provided fire rated cable is used. In this configuration, operation of the refuge point overrides the assistance call, making it ideal where a disabled toilet is adjacent to a refuge lobby.

What happens when someone activates the pull cord?

When activated, the over-door indicator and cancel plates emit an alternating tone with flashing blue indication. After system acknowledgment, the indicators change to steady illumination with a double beep tone every 15 seconds to reassure the occupant that help is on the way.

What is the “Acknowledge” feature and why is it important?

The “Acknowledge” feature is required by BS8300-2:2018 for remote locations. It provides audio confirmation (double beep every 15 seconds) and visual confirmation (steady blue light) to the person in distress that their call has been received and help is coming.

What cable types and distances are supported?

The system supports PVC or fire rated 2 core 1mm cable up to 500m from the panel/controller, or Cat5/6 cable (1 x pair 0.22mm) up to 50m distance.

Can the system be expanded for other locations?

Yes, the ViAC-ACA-W kit can be expanded using additional plates making it suitable for accessible bedrooms and other locations described in Building Regulations Approved Document M2 2020 and BS8300. It’s also compatible with the ViAC-4ZC-SS four zone control module.

Is the system suitable for public use?

Yes, the ViAC-ACA-W is specifically designed to be used by the public as an emergency assistance alarm. It includes features like Braille enhanced cancel buttons for accessibility and complies with all relevant accessibility standards.

What are the main advantages over self-contained units?

The key advantages include no local mains PSU requirement at the WC, all field wiring is monitored for integrity, central indication capability, and the acknowledge feature as required by BS8300-2:2018. This provides better reliability and compliance compared to standalone units.
