Halton Safe HSL – Link unit
Independent fire damper link unit to be connected to 1-4 fire dampers and 1-4 smoke detectors.
- Controlling fire dampers and smoke detectors in buildings.
Overview
Halton Safe HSL link unit is a part of Halton fire and smoke safety offering.
This is an independent fire damper link unit to be connected to 1-4 fire dampers and 1-4 smoke detectors.
Halton Safe HSL link units use an internal communication bus to communicate with the Halton Safe Management 2.0 controller. The link units are programed from the Halton Safe Managenent 2.0 controller. Halton Safe HSL link unit contains a memory, which ensures that their settings are not lost even if the power supply to the system fails. If the connection to the controller is lost, the link units continue running independently.
Halton Safe HSL link units include a 24 V DC power supply for smoke detectors. The system is designed to be used with the following types of smoke detectors: Halton Safe HSR, smoke sensor in room and Halton Safe HSD, smoke sensor in duct.
Applications
- Controlling fire dampers and smoke detectors in buildings.
