This chapter provides basic guidelines for installing the detector. It does not
attempt to cover all of the standard practices and codes of installation.
Rather, it emphasizes specific points of consideration and provides some
general rules for qualified personnel. Wherever applicable, special safety
precautions are stressed.
2.1 General Guidelines
To ensure optimal performance and an efficient installation, consider the
following guidelines:
• Sensitivity: To determine the level of sensitivity, consider the following:
• Size of fire at the required distance to be detected
• Type of flammable materials
• Wiring:
• The wire gauge must be designed according to the distance from the
detector to the controller and the number of detectors on the same
power line. See Wiring Instructions on page 47.
• To fully comply with EMC directive and protect against interference
caused by RFI and EMI, the cable to the detector must be shielded
and the detector must be grounded. The shield should be grounded
at the detector end.
• Spacing and Location: The number of detectors and their locations in
the protected area are determined by:
• Size of the protected area
• Sensitivity of the detectors
• Obstructed lines of sight
• Cone of view of the detectors
