Halton Safe Management 2.0 is a fire and smoke safety system that consists of a Halton Safe Management 2.0 controller combined with several Halton Safe HSL link units that manage Halton fire dampers and smoke detectors. When a fire breaks out, the system controls the shut-off operation of fire dampers based on alarm indications from thermal fuses, smoke detection, or external alarm inputs.
Halton Safe Management 2.0 is a fire and smoke safety system that consists of a Halton Safe Management 2.0 controller combined with several Halton Safe HSL link units that manage Halton fire dampers and smoke detectors. When a fire breaks out, the system controls the shut-off operation of fire dampers based on alarm indications from thermal fuses, smoke detection, or external alarm inputs.
The Halton Safe Management 2.0 controller enables automatic, manual, or external testing of fire damper operation, including test reporting. You can set the controller to shut off the fans during testing and in a fire situation.
The Halton Safe Management 2.0 controller has outputs for remote fire and service alarm indications. It also has local alarm indication for fire and service alarms. You can connect the controller to the Building Management System (BMS) via BACnet/IP.
You can extend the Halton Safe Management 2.0 system modularly with up to 50 pieces of Halton Safe HSL link units to which the fire dampers and smoke detectors are connected. 1–4 fire dampers and 1–4 smoke detectors can be connected to each Halton Safe HSL link unit. The link unit’s internal control logic is used in managing the fire dampers and smoke detectors. An internal communication bus is used between the Halton Safe Management 2.0 controller and Halton Safe HSL link unit. Halton Safe HSP power units provide power to Halton Safe HSL link unit.

Fire dampers and smoke detectors can be clustered into as many as 15 alarm groups, enabling the system to respond to a fire alarm by closing only those fire dampers that are in the affected fire compartment. You can set each fire damper or Halton Safe Link unit to function as an independent alarm group.
The fire dampers can be set to be automatically tested at a specified time, or you can start a test manually. The system creates a report of the tests carried out, indicating the functionality of each fire damper. If the actuator of a fire damper is not functioning properly, the system activates a service alarm.
The system can be used with the 10.1″ graphical touch screen user interface. Optionally, you can also have a remote connection (4G, for example) that enables you to use the system through a web browser.
If the power supply to the system fails or there is a fault in the Halton Safe Management 2.0 controller, the Halton Safe Link units continue operating independently. If a Halton Safe HSL link unit loses its operating voltage because of a fire or because the power supply to the system fails, the fire dampers are closed by a spring. It is also possible to connect a backup battery to the Halton Safe Management 2.0 controller to make sure the system can relay alarms also in case the power supply to the system fails.
When designing a fire safety system, consider the following:
How are dampers controlled in an alarm situation: should all dampers close or are dampers defined in different alarm groups?
How does the damper status affect the fans?
When designing a Halton Safe Management 2.0 system, take into account the following information related to commissioning and maintenance:
The project-specific parameters of the controller are configured during system commissioning on site. Wiring needs to be checked before the system start-up.
The Halton Safe Management 2.0 controller addressing is pre-set at the factory. If addressing needs to be changed later or if any system parameters need to be modified, it can be done from the controller user interface.
Halton Safe HSL link unit addressing is defined during system commissioning. Each Halton Safe HSL link unit must have a unique address. The addresses are defined by using the DIP switches in the Halton Safe HSL link units.
For more detailed commissioning and maintenance instructions, see Halton Safe Management 2.0, Installation, commissioning, operating and maintenance guide.
In this configuration, the Halton Safe Management 2.0 controller controls three alarm groups. Each alarm group includes several Halton Safe HSL link units to which the fire dampers are connected. The building has a separate fire alarm system that it is connected to the external fire alarm inputs of the Halton Safe Management 2.0 controller with cables. The Halton Safe Management 2.0 controller is connected to the Building Management System (BMS) with cables. The separate fire alarm system is also connected to the BMS. The Halton Safe Management 2.0 controller gives the running permission to the Air Handling Unit (AHU).
When the fire alarm system sends an alarm to the Halton Safe Management 2.0 controller or the thermal fuse of a fire damper gives an alarm indication the Halton Safe Management 2.0 controller closes certain alarm groups and forwards the status of the alarm groups to the BMS system. Depending on the alarm groups in question, the Halton Safe Management 2.0 controller keeps the AHU running or stops it. The fire alarm system also sends an alarm indication to the BMS.
