FAQs

What is the difference between the ViAC-CLP-66 call button and the ViAC-CNP-66 cancel button?

The ViAC-CLP-66 is a call button used to activate/raise an alarm, while the ViAC-CNP-66 is a cancel button used to cancel/acknowledge an alarm. The call button is pressed by a user who needs assistance to initiate an emergency call. The cancel button is typically pressed by responding staff to acknowledge and cancel the alarm once assistance has been provided. Both share the same IP66 weatherproof construction and physical specifications, but serve opposite functions in the alarm system workflow.

How many ViAC-CLP-66 call buttons can be installed on a single line?

There is a maximum of 6 call buttons that can be installed on a single line. When multiple call buttons are connected, the system registers the last button that was operated. This allows multiple call points in a larger facility or area while maintaining system simplicity. If your installation requires more than 6 call buttons, you would need to use additional zones or circuits.

Can the ViAC-CLP-66 replace a pull cord?

Yes, the ViAC-CLP-66 can be used in place of a pull cord, but this should only be done with agreement from all interested parties. This is an important consideration as pull cords are traditionally used in disabled toilets and accessible facilities, and any deviation from standard pull cord installation should be discussed with facility managers, care staff, and potentially regulatory bodies to ensure accessibility requirements are still met. The call button only provides visual indication (no audible sounder).

What systems is the ViAC-CLP-66 compatible with?

The ViAC-CLP-66 is fully compatible with several Vox Ignis and Lexicomm systems including: the Lexicomm EVC range of equipment, Lexicomm LX228 panels, Lexicomm Network range of panels, AssistCall standalone 4 Zone controllers, AssistCall 1 Zone controllers, and the ViAC-RTK Remote kit. This wide compatibility makes it suitable for both new installations and retrofits to existing systems.

What is the correct mounting height for the call button?

The ViAC-CLP-66 should be mounted between 800mm and 1000mm from the floor in accordance with BS 8300-2:2018 standards. Additionally, a lower call button should be mounted at 100mm from the floor to ensure accessibility for users who may have fallen or are in different positions. This dual-height arrangement ensures the emergency call system is accessible in various situations.

What does the IP66 rating mean and can the device be immersed in water?

IP66 is an Ingress Protection rating that indicates the device is completely dust-tight (6) and protected against powerful water jets from any direction (6). This makes it ideal for wet environments such as showers and bathrooms. However, it’s critically important to note that this product must not be immersed in water. The IP66 rating protects against water jets and splashing, but does not provide protection against full submersion.

What wiring is required for installation?

Installation uses simple standard two-core cable. The wiring order of devices is not fixed and can be connected in any order, giving total flexibility during installation. The cable should be connected to the Line + and 0 terminals. There are two sets of 2-part removable terminals which are not marked as in or out – it doesn’t matter which is used for incoming or outgoing connections, however polarity is important and must be observed. Recommended cables are 2 core 1mm PVC or fire rated cable up to 500m, or Cat5/6 (1 pair 0.22mm) up to 50m from the panel/controller.

Where should drain holes be positioned?

For side, top, or rear cable entry installations, the lowermost drain hole must be drilled out using a 5mm drill – only one drain hole position should be drilled. For bottom cable entry, a drain hole must NOT be drilled in the rear box, but must be drilled at the lowermost point of the conduit run. It’s important to note that opening the drain hole will compromise the IP66 rating of the product, so particular care should be taken to ensure no water is directed at the drain hole once installed.

How should the stainless steel finish be maintained?

Over time, environmental conditions and weathering may affect the stainless steel finish, particularly in coastal regions where some discolouration may occur. It is recommended that the surface is cleaned with a soft cloth soaked in neutral oil, such as WD-40. This cleaning process should be repeated up to 4 times per year to maintain the appearance and protective qualities of the stainless steel finish.

How does the visual indicator work?

The ViAC-CLP-66 features a blue visual indicator that illuminates when the button is pressed, confirming that the alarm has been activated. This provides immediate feedback to the user that their emergency call has been registered. The momentary sprung switch means the button returns to its normal position after being pressed, but the alarm remains active until cancelled by staff using a cancel button.

What is the EOL resistor and when should it be fitted?

EOL stands for End Of Line resistor. If the ViAC-CLP-66 is the last device in the circuit, the EOL resistor should be fitted to the unused terminal set. This is applicable for monitored line circuits and allows the control panel to detect faults in the wiring such as open or short circuits. Note that 1 Zone controllers do not have monitored line circuits and therefore do not require an EOL resistor.
