When do I require a Verification?
Modifying an existing Fire Alarm System
Code Reference: CAN/ULC-S537-13
- Where devices are added to an existing system, a verification is required.
- Questions we will ask:
- Are the added devices compatible with the control unit or transponder and other devices on the wiring circuit?
- Has the loading of the circuit been exceeded with the additional device(s)?
- Is there sufficient emergency power being provided for the additional device(s)?
- Where a control unit or transponder is added to an existing system, the control unit or transponder and all new and existing field devices connected to it shall be verified.
- Where an existing fire alarm system, control unit, transponder or annunciator is replaced with a new control unit, transponder or annunciator, it shall be verified in accordance with Section 5, Verification Procedures – Control Units and Transponders, and any existing devices shall be tested in accordance with Subsection 6.7, Field Devices, of CAN/ULC-S536, Standard for Inspection and Testing of Fire Alarm Systems.
- Conventional Fire Alarm Systems:
- Where a conventional field device is added, or modifications or deletions are made to an existing input circuit or output circuit AND the new or altered wiring is extended from an existing field device, the new device(s), the device connected on either side of the addition or alteration, as well as at the end-of-line device for that circuit shall be verified.
- Where a conventional field device is added, or modifications or deletions are made to an existing input circuit or output circuit, and the new, modified or altered wiring is extended from a junction box, all devices served by that circuit shall be verified.
- Where an existing defective field device is replaced with an identical field device, the device shall be verified for its intended function UNLESS the replacement does not require the disconnection of any of the wiring.
- Addressable Fire Alarm Systems:
- Where a data communication link(s) is added to an existing system, all new and existing field devices connected to that data communication link(s) shall be verified.
- Addition, modification, or deletion of active field device(s) and supporting field device(s), to an existing data communication link shall require verification of the new or altered device(s). In addition, either an operational test of all devices connected to that data communication link shall be performed.
- Software or firmware modifications shall be tested by one of the following methods:
- Reverifying all system functions that could be affected by the modifications with the exception of wiring supervision
- A comparison of the before and after software utilizing mediums such as a printout or compare program.
