between the central unit and LINK units is based on the Modbus protocol. It is possible to connect
1–4 fire dampers and smoke detectors to one Halton Safe Link control unit (optionally special Link is
capable of connecting 1-12 smoke detectors and zero fire dampers).
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 Halton 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 Linkcontrol
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 damper test function shall be triggered by an automatic function at adjustable intervals,
manually, or from an external system. The system shall be able to shut off the fans for the duration
of the test cycle.
In the case of fire, the management system shall be able to close all of the fire dampers and shut off
the ventilation fans in a common service area. The fire alarm shall be activated by a thermal fuse or
a fire damper, a smoke sensor alarm, or an external alarm indication.
The unit shall be constructed in a cabinet, which shall be easy to install on site. The cabinet shall
meet the requirements for protection class IP40.
Smoke detectors shall be for ductwork or room installation.
