Lexicomm Roaming Fire Telephone Jackpoint
Summary
The Lexicomm ViLX-OSJ and ViLX-OSJ-S are jack point wall plates designed for use with roaming fire telephone systems in high-rise buildings. These jack points provide connection points throughout a building where firefighters can plug in ViLX-OSR roaming handsets to establish immediate communication with the master control station, particularly useful in situations where radio systems may not work effectively due to building construction or fire conditions.
The jack points are easy to use – to initiate a call, the roaming telephone handset is simply plugged into the jack point which automatically initiates a call to the master station. Full duplex operation provides clear two-way conversation, and the Lexicomm EVC and UnicornVoice PAVA systems support up to 5 telephones connected to the same line to have a “party line” conversation with the master station simultaneously, enabling coordinated emergency response communications.
Both models feature brushed stainless steel construction in a compact 86mm x 86mm format that fits standard MK style 25mm flush or surface back boxes. The jack points are compatible with all Lexicomm and UnicornVoice panels, and multiple jack points can be wired on a single EVC line. While jack points are generally used in Far East and Middle East markets and their use in the UK is not allowed, the ViLX-OSJ-S variant offers an additional feature: it provides an isolated volt-free contact that can signal to other systems when a roaming fire telephone has been inserted into the jack point, enabling integration with building management or security systems.

FAQs
What are the ViLX-OSJ and ViLX-OSJ-S jack points used for?
The ViLX-OSJ and ViLX-OSJ-S are wall-mounted jack points that provide connection points throughout a building for ViLX-OSR roaming fire telephone handsets. When a handset is plugged into the jack point, it automatically initiates a call to the master control station, enabling firefighters to communicate from any location in the building.
What is the difference between ViLX-OSJ and ViLX-OSJ-S?
The ViLX-OSJ is the standard jack point model. The ViLX-OSJ-S includes an additional feature: an isolated volt-free contact switch (NO, NC and common) rated at 100mA 30V that provides a signal when a roaming fire telephone has been inserted into the jack point. This allows the system to signal to other building management or security systems.
How many jack points can be installed on a single line?
Multiple jack points can be wired on a single EVC line. The system supports enhanced fire resistant 1.5mm CSA cabling up to 500m from the panel to the last jack point, allowing extensive coverage throughout large buildings.
How many people can communicate simultaneously?
The Lexicomm EVC and UnicornVoice PAVA systems allow up to 5 roaming telephones connected to the same line to have a “party line” conversation with the master station at the same time, enabling coordinated emergency response across multiple locations.
What height should the jack points be mounted at?
The jack points should be mounted at a height of 1300 to 1400mm from the floor to the centre line of the jack point, in a standard MK style 25mm flush or surface back box.
Are these jack points allowed in the UK?
No, jack points are generally used in Far East and Middle East markets. Their use in the UK is not allowed under current regulations, which typically require fixed fire telephone outstations instead.
What type of handsets work with these jack points?
The jack points are designed to work with ViLX-OSR roaming fire telephone handsets that feature a 1/4″ mono jack plug connector with integral coiled cable.
Which control panels are compatible with these jack points?
The ViLX-OSJ and ViLX-OSJ-S jack points are compatible with all Lexicomm and UnicornVoice panels, providing flexibility for different system configurations.
What type of back box is required?
The jack points fit in a standard MK style 25mm flush or surface back box. The compact 86mm x 86mm dimensions make them suitable for standard single gang electrical box installations.
What is the volt-free contact used for on the ViLX-OSJ-S?
The isolated volt-free contact on the ViLX-OSJ-S provides a signal when a roaming fire telephone has been inserted into the jack point. This can be used to signal to other systems such as building management systems, security systems, or monitoring equipment, enabling integration with broader building safety infrastructure.
What standards do the jack points comply with?
The jack points comply with EMC standards EN 55035:2017+A11:2020 and EN 55032:2015+A1:2020, plus LVD standard EN IEC62368-1:2020+A11:2020.
