Chapter 17 – Initiating Device

Initiating devices shall be installed in a manner that provides accessibility for periodic inspection, testing and maintenance.

“Accessible Spaces”:

• Spaces or concealed areas of construction

• Space that can be entered via panel, door hatches, ceiling tiles

• Applies only for the purpose of determining extent of detector coverage, relevant when “Total Coverage” used

17.4.4 Accessible installation

required


Initiating Devices – Total Coverage

Section 17.5.3

• Detection in all places practical and that may present

combustible materials

• Spaces that can be accessed by doors, panels, ceiling tiles

• Recognizes conditions where it is not practical to install

detectors

• Recognizes where air movement is useful for detection

schemes

• Considers special conditions related to smoke detection and

smoke compartments


Total Coverage – Scenario 1

Combustible concealed space

Ceiling Line

Concealed

Space must

be made
