Lexicomm AssistCall Ancillary Cancel in Stainless Steel

FAQ

What is the difference between a standard cancel plate and an ancillary cancel plate?

The ancillary cancel plate does not provide any visual or audible indication when pressed, unlike standard cancel plates. It should only be used as an additional cancel point alongside standard cancel plates or over-door indicators that provide the necessary feedback to confirm alarm cancellation.

How many ancillary cancel plates can be added to a circuit?

Generally, up to two ancillary cancel plates can be added to a standard dedicated AssistCall ACA or ACB circuit, allowing for a total of four cancel locations (two standard cancels and two ancillary cancels). Always check with Vox Ignis Technical for specific installation requirements.

Where would ancillary cancel plates typically be installed?

Ancillary cancel plates are commonly installed on the opposite side of a bed in accessible bedrooms, providing cancel functionality for users who may transfer to either side. They should be mounted between 800mm to 1000mm from floor level to comply with accessibility regulations.

Can ancillary cancel plates be used without standard cancel plates?

No, ancillary cancel plates should never be used without standard cancel plates or over-door indicators nearby. Since they provide no visual or audible feedback, users would have no confirmation that their alarm cancellation has been registered by the system.

What wiring requirements apply to ancillary cancel plates?

The ViAC-ACP uses standard 2 core cable wiring (1mm LSF flex/T&E for 500m distance, or 0.22mm Cat5/6 for 50m on 1 pair/100m on 2 pairs). The plates can be wired in any order, provided the 10kΩ end of line resistor is placed in the final plate.

What back box requirements are needed for installation?

The ancillary cancel plate mounts onto a 25mm UK single gang back box, compatible with any “MK” style single back-box over 25mm deep. For cable glands, the back box needs to be 35mm deep, including metal clad surface types and plastic plasterboard dry liner boxes.
