If the zone to be protected is a classified area affected by directive
94/9/EC, ATEX, be sure to design the installation and use equipment
that meets the classification requirements.
Danger of electric shock. Disconnect all power from the panel before
carrying out any work
A loop cable transmits data, so choosing the right cable is important.
Observe the following:
• The loop cable must not exceed 2 km, including possible branches (not
recommended).
• Only twisted pair and shielded cables must be used. The cables must
circulate through ducts that are separated from other circuits to prevent
problems of interference.
• The screen must always be earthed at a single point. Use the connection
points described for the mesh.
• The mesh must have continuity throughout the loop ring path.
• Although for a standard facility the cross section of the loop cable is
usually 1.5 mm². Calculate the exact cross section required for your
facility.
• The sheath for the cable intended for fire detection applications is
normally red.
• The cables specified for the loop circuits are also suitable for alarm,
auxiliary alarm and input/output transmission lines.
• All cable sections must be circular so that the cable is secured effectively,
using cable glands.

1.11. REQUIREMENTS
1.11.1. Assembly notes
KNOWLEDGE: Make sure you have the necessary mechanical and
electrical knowledge to assemble this panel on the wall and implement
the necessary connections to your mains network.
TOOLS: To assemble the control panel, you will need:
• An electric drill.
• A Phillips or Pozidrive screwdriver.
• A small flat screwdriver for the terminals.
• Insulating tape.
• Measuring tape.
• Cutter.
• 4 lag screws 5.5-6 mm in diameter and 40 mm in length.
• 4 DNP8 wall plugs (8 mm in diameter).
1.11.2. Installation notes
Once the control panel is assembled and connected to the mains
network, you can carry out an initial start-up and configuration. The
detection control panel must only be installed in a dry, clean and well-lit
area with restricted access.
Prevent electrical/electromagnetic and mechanical interferences, such
as installing the panel close to fluorescent lights, electrical power lines,
surfaces that vibrate or are unstable and thin partition walls
1.11.3. Detection loop wiring
The wiring must be checked by a certified installer to make sure that all
connections work properly and there are no earth faults.
All wiring must comply with applicable local standards. Observe
the requirements of the
UNE 23007-14
standard for wiring and
interconnection of a fire alarm system.
