Function
The central unit can be modularly extended with Halton Safe Linki control units, to which the fire
dampers and smoke detectors are connected. You can connect 1–4 fire dampers and 1–4 smoke
detectors to one SAFE LINK control unit. The unit’s internal control logic is used in their
management.
Fire dampers and smoke detectors can be clustered into as many as 15 groups, enabling the
system to respond to a fire alarm by closing only those fire dampers that are in the affected fire
compartment. Each fire damper or SAFE LINK control unit can also be set to function as an
independent group.
The fire dampers can be automatically tested weekly, at a time specified by the user. The system
creates a report on the tests carried out, indicating the functionality of each fire damper. The
system is used with a 5.7″ graphical touchscreen, through which all necessary user operations can
be performed. The system can be equipped with an optional 3G remote connection that makes all
of the touchscreen’s functions available via a Web browser.
In the event of a power cut or a fault in the Halton Safe central unit, the Halton Safe Link control
units operate independently. If a Halton Safe Link control unit loses its 24 VAC operating voltage
because of a fire or a power cut, the fire dampers are closed by a spring. It is also possible to
connect a backup battery to the central unit, so that the system can relay alarms even in the event
of a power cut. The operating voltage of the Halton Safe control centre is 230 VAC.
