It is our aim to introduce the concept of a standalone call and communications system in this catalogue and to give you an idea of the wide range of equipment that is available to successfully realise the concept. It would go beyond the scope of the catalogue to mention all of the possible uses and applications. Every facility is organised differently, so it will still be necessary to find individual solutions that are as cost-effective as possible. Technical advances happen so quickly that a catalogue is already due for revision almost as soon as it is published. Please ask our advice and...

FOREWORD This product overview is designed to give a comprehensive picture of our security products. It is intended for planning departments, installers and operators, and is designed to support the planning and installation of security systems. For more than 40 years now, the EFE Elektronik- Forschungs- und Entwicklungsgesellschaft m.b.H. in Mühltal near Darmstadt, has been developing and producing a wide range of equipment for use in research and industry. It has successfully designed nurse communication systems for hospitals, senior citizen’s homes and nursing homes and security systems...

CHARACTERISTICS Prisoners in places of detention have restricted freedom of movement and are locked into a small space for long periods. Obviously, forcing people with widely differing educational histories and personalities to live together under these conditions often creates social tensions, with an ever-present risk of physical and mental aggression towards others, towards themselves or towards the facilities. The prisoners face these risks, but also officers whose job is to supervise and support them. There is a special duty of care, which means that the prisoner’s recreation areas and...

In addition to these minimum requirements, certain other characteristics are necessary to support the primary functions. Cell-based two-way or one-way communication with call query Authorised eavesdropping in hostage situations Radio reception Forced override WC call Time alarm for officer presence Window or window-bar alarm Lamp alarm Light switching Fire alarm Alarm loops Sabotage alarm Mobile phone detector Formation of hierarchical groups Zone master stations Section master stations Central or command master stations Centralised and localised operation Alarm acknowledgement Alarm...

As the technology in places of detention, court houses, forensic clinics and police buildings becomes more heterogeneous, individual officers are faced with a bewildering array of systems to operate and monitor. Keyboards, monitors and intercom devices can start taking over the workplace - for video surveillance, fire alarms, perimeter security, two-stage entry systems, cell management and much more. Each system presents a different picture of the prison, with manufacturers changing their interpretation to suit their particular application. Building management or alarm management systems...

SYSTEM FEATURES The EFE cell call and communication system is a centralised and/or localised system, representing the state of the art in terms of technology, reliability and flexibility. It is very easy to install and maintain, and any malfunctions can be identified immediately and eliminated reliably by replacing modules. 1. The system complies with the mandatory light call standards and has been adapted to the regulations of the individual German federal states. 2. The system consists of various types of autonomous microprocessor-controlled devices, which are connected to cables in bus...

FUNCTIONS Presence indication The presence of an officer in a cell or in a section usually is indicated with a key-operated switch. The switch is connected to the cell terminal. The connected cell signal lamp and any relevant direction arrows show a constant green light. The WC call is triggered either by a cord pull switch or some other external switch. It switches on a constant white light in the cell signal lamp and a constant red light in the relevant direction arrows and in the group lamps. The call type and call location are indicated on the corridor display, if there is one. The...

Window or window-bar alarm The window alarm is triggered cell-by-cell by a surveillance circuit. It causes a red light to start flashing in the cell signal lamp, in the relevant direction arrows and in the group lamps. The alarm type and location will be indicated on the corridor display, if there is one. The window alarm is indicated by a locationdependent, flashing red light on the highest-level master station, with an intermittent audible signal until it is acknowledged. The alarm can be acknowledged by establishing a voice connection from the relevant master station. The alarm loop has...

Detection alarm A detection alarm can only be triggered if there is a mobile phone detection system (comstop®). The alarm detecting the use of mobile phones (locally specific mobile phone frequencies) is assigned to a cell terminal on the basis of a field strength analysis covering the building as a whole, where it is triggered remotely. The alarm causes a red light to start flashing in the cell signal lamp and in associated group lamps. The alarm type and location will be indicated on the corridor display, if there is one. The detection alarm is indicated by a locationdependent, flashing...

Fault indications The call and presence inputs are covered by bias current monitoring, which involves measuring and evaluating the voltage level. If the level moves outside the permitted range, the cell terminal issues a fault indication. The message switches on a constant red light in the cell signal lamp, in the relevant direction arrows and in the group lamps. Light can be denied temporarily to all cells in a zone (cell light circuit 1). This is done on a zone basis by pressing the light denial button at the relevant master station. With the correct programming in the cell terminal,...
