Field Device Installation Guideline (Canada)

 

Additional requirements are outlined in the Standard for Installation of Fire Alarm Systems (CAN/ULC-S524) that is referenced by the current Building Code in effect.  Please refer to the applicable Standard for more detailed requirements.  This table’s focus is as a convenience guideline for basic wall-mounted device installation heights only.  The manufacturer’s installation instructions should be consulted for termination of wiring and approved mounting methods.  Notes referenced in the table are provided below. 

It is extremely important that the installer review the manufacturer’s instructions that detail the proper installation, mounting, wiring, and termination of the control equipment and field devices to avoid errors that could prove costly!

Please review our terms of use!

You can also download the PDF of the Installation Guide!
When printed, it should fit on a single double sided sheet which
you can laminate and carry around as a handy reference!

Errata:  The line item for the “.030 Ampere/16AWG” entry is shown as “150 feet” in Table 5 of the FA-1000 installation manual.  We have converted the “229 meter” entry on the line next to it to reflect the corrected Imperial measurement of “751”.

NOTES:

1.  End-of-Line Resistors may be mounted in a properly identified common termination box or inside the fire alarm system’s common control in which case a suitably secured terminal block must be used (it is not acceptable for resistors to be “floating” inside a back-box).

2.  Wiring methods and bonding to ground of field device’s back-boxes is referenced in the Canadian Electrical Code, and CAN/ULC-S524 (Standard for Installation of Fire Alarm Systems).

3.  The “Initiating Circuit” table above references wiring of remote annunciators.  All Mircom remote annunciators are wired in parallel in a continuous loop to the last unit.  No “T” tapping is allowed (either for power or data).  Twisted shielded wire is required for the RS-485 Data Buss with a separate wire pair for power.  DO NOT USE a single five conductor cable for both data and power!  It must also be noted that each manufacturer will stipulate the type and gauge of wire to use when connecting remote annunciators.  READ THE MANUAL!

4.  In-suite sounders connected to isolators must be fully supervised for opens, shorts, and ground faults.  The use of isolators that supervise for shorts and ground faults only is prohibited in Canada!

5.  “Visible and accessible at all times” would normally make the installation of any isolator serving a floor area (or suites of a residential or care occupancy) inside an electrical closet non-compliant.  The Installation Standard (Clause 5.4.3.3 in 06 and Clause 10.2.6.2 in 14) specifically requires isolators serving audible appliances in suites of a residential or care occupancy to be located OUTSIDE of the suite they’re protecting.  It is strongly recommended that you consult with your local jurisdictional authority as to how they’re going to interpret the relevant clauses and ensure the system Verifier makes the appropriate notation in the Verification Appendix “C” report.

6.  While installation heights are not specifically mentioned in most manufacturer’s printed installation instructions, we would recommend that you install these modules not higher than 1800 mm above the finished floor (for ease of access).  Some mini initiating modules are designed to “float” in a single gang backbox (usually mounted behind a conventional device).  We recommend that you identify any such conventional field devices where these modules have been so utilized.
