Product Usage Instructions
Installation
- Ensure the cable is installed in the designated area according to the provided guidelines.
- Connect the Proline EN Digital LHD cable to the Digital Sensor Control Unit (Z1-02 EN) as per the installation instructions.
- Verify the proper functioning of the system before finalizing the installation process.
Maintenance
Regularly inspect the cable for any signs of damage or wear. If any section of
the cable has been activated, it must be cut out and replaced promptly to
ensure continued safety.
Testing
Periodically test the system to ensure it responds correctly to changes in
temperature. Follow the testing procedures outlined in the user manual.
FAQ
Q: Is the Proline EN Digital LHD cable reusable after activation?
A: No, once a section of the cable has been activated, it must be cut out and replaced. The cable is non-resettable.
Q: What are the maximum ambient temperature limits for the different Proline EN Digital LHD cable models?
A: The TH68EN model has a maximum ambient temperature of 45 degrees C, TH78EN also has a maximum of 45 degrees C, and TH88EN has a maximum of 65 degrees C.
Q: What is the minimum ambient temperature that the Proline EN Digital LHD cable can withstand?
A: The cable can withstand a minimum ambient temperature of -40 deg C.
General Overview
Proline EN Digital Linear Heat Detection (LHD) cable uses fixed temperature
detection technology to provide a straightforward method for sensing
temperature changes. The cable can offer alternative overheat protection in a
vast range of applications and environments, from tunnels, cable trays, and
warehousing to sensing changes in temperature within escalators and other
applications where many risks of fire are hidden from view. Proline EN Digital
LHD cable is a non-resettable line-type heat detector. The two twisted cores
and held apart by an advanced temperature-sensitive polymer. At a temperature,
set by the manufacturing processes of the cable, the temperature-sensitive
polymer surrounding the two cores softens, allowing the cores to come into
contact. This is an irreversible process and once the cable has activated, the
section that has triggered must be cut out and replaced
(not the whole cable).
Digital Sensor Control Unit (Z1-02 EN)
The Proline EN Digital LHD cable has been approved to EN54-28:2016 in
conjunction with the Proline Digital Sensor Control Unit (Z1-02 EN). The Z1-02
EN monitors up to two zones of Digital LHD cable and has separate fault and
alarm outputs for each zone. It is straightforward to connect the Z1-02 EN to
a conventional fire alarm panel or to an addressable system using an I/O, zone
or switch monitor module. It also has a built-in display that shows the state
of each zone, including the distance in metres and feet to the alarm point, if
an alarm is triggered. Furthermore, an RS-485 Modbus RTU/ASCII output is
available as standard for integration with a PLC or SCADA system.
