Wireless Fire Linking System

The Scope F-Link mesh network system has become the de facto and secure way of remotely alerting and monitoring fire or security systems located in adjacent buildings.


Practical, fast and flexible installation


F-Link is housed in a large case with plenty of cable entry points and an informative text display which provides status information and gives details of all alarm messages. Plug & play installation includes “press to join network” feature and auto-reconfiguration if a unit needs to be replaced or moved.


A system consists of two or more F-Link units working together to form a mesh network with each unit operating as both a transmitter and receiver. The radio link between units is monitored for faults in accordance with the relevant sections of BS5839-1:2017 (24.2b) and BSEN54-25:2008 (4.2.6).


There is an additional RS232 serial output on the Master unit for connection to either or both the FLINK XP relay expansion unit, and an optional FLINK paging transmitter, which sends alarm and fault messages to pocket pagers.

Operational Features


The front panel display indicates active zones, unit status, network/radio status and the received signal strength of incoming transmissions. A button is provided to mute the internal fault sounder, a keyswitch allows the unit to be reset or placed into test mode.


The Identity and radio operating frequency of each unit is set using dip switches, allowing for rapid and fuss-free installation.


Where required, additional features can be programmed using Windows-based configuration software (available from Scope). Software-configurable options include: Text descriptors for each Node and each zone event; zone input type; and output relay operating mode. Programmed settings are transmitted by the Master unit to all installed Nodes.


An optional F-Link paging transmitter can be added to the system to send alarm and fault event descriptions to portable radio pagers. An optional interface can also be specified to provide a serial data output for logging purposes.
