CellCall - Personal Safety Systems

Supernet Digital

In high-risk establishments the safety of the staff and residents is paramount. This requires an immediate response to any incident affecting personal protection. The Supernet Digital system is readily adaptable to any circumstances in which such personal safety is required, for example; Hospitals, Prisons and other Secure Establishments, or where there is a risk to lone workers on large industrial or commercial sites. The system can be designed to meet the precise needs of the area in which it is to be installed.

Alarm Initiation

Alarms may be initiated by the use of pushbuttons, keyswitches and callpoints. In addition, the system can incorporate a wireless alarm segment, either as a separate system, or overlaid on the hardwired system for backup in high risk establishments.

Text message for precise location

Once an alarm call has been triggered, the system will display the precise location with a text descriptor on the Supernet Digital control panel, which is commonly located in the supervisor's office. As well as this, the system can be designed to have lamp and buzzer units. To ensure a quick, accurate response to an incident or alarm, we can also supply a high-visibility text message display, which can be read from 20 metres distance.

Alarm Prioritisation

The system can be constructed to include different levels of alarm, each requiring different responses. For example; the input device could signal a Personal Attack, or a Nurse Call, or even a Door Status. Each type of signal can be displayed and outputs operated depending upon its importance.


The standard alarm station uses a vandal-proof pushbutton with integral illumination. Pressing the button sends a signal to the Supernet Digital control panel, which in turn sends a confirmation signal to illuminate the button, so giving the user confidence that the event is being acted upon. The pushbutton alarm stations include an addressable communications module, which minimises cabling costs, and is fully monitored. The standard unit is supplied with a stainless-steel flush fascia, and there are a range of sizes to fit many different backbox styles. Surface-mounting buttons, pull-cord switches and other special sizes can also be supplied. All units can be supplied with tamper-resistant screws for secure establishments.

Staff Alert Modules

As with the alarm initiation devices there are a number of options. The basic unit has a large, high-visibility LED, which illuminates to show the location of the alarm. Additionally, these units can incorporate an audible warning. Because they are also fitted with addressable modules to minimise cabling, they can be programmed to your precise requirements, ensuring a speedy response to an incident. Typically, they would be located in corridors outside the protected rooms, to guide personnel in the event of an emergency. Allied to the text description from the Supernet Digital control panel, this makes the task of finding an incident much more efficient. These modules can be connected to the same cabling as the Alarm Stations, to reduce the installation costs.

Text Message Modules

The system can incorporate a high-visibility Moving Message Display, which repeats the text description from the control panel, and would typically be located in Supervisor areas or Control Rooms. With 50mm characters, it can be read from a distance. If there are multiple events, they are displayed sequentially. These units are also addressable, and each can be individually programmed to display any or all events from the systems.


In larger systems, the Supernet Digital control panels can be connected to form a network, so allowing events from many areas to be displayed. Networking means that each area can retain stand-alone autonomy, while ensuring that there is site-wide supervision and control.

The system can include different levels of alarm, requiring different responses. For example the input device could signal a Personal Attack, a Nurse Call, or even Door Status. Each type of signal can be displayed and outputs operated depending upon its importance.
