ANSI/CAN/UL 2684:2024
Scope
1.1 This Standard sets forth requirements for video and thermal image fire detectors and accessories for
non-dwelling units, including mechanical guards to be employed in indoor locations (for video and thermal)
and outdoor (for thermal) in accordance with the following:
a) In the United States:
1) National Fire Alarm and Signaling Code, NFPA 72;
2) National Electrical Code, NFPA 70.
b) In Canada:
1) Standard for the Installation of Fire Alarm Systems, ULCS-S524;
2) National Building Code of Canada; and
3) National Fire Code of Canada.
1.2 A detector as covered by this standard consists of an assembly of electrical and mechanical
components to sense:
a) Smoke in the visible and/or infrared wavelengths; and/or
b) Flame in the visible and/or infrared wavelengths; and/or
c) Heat in the infrared wavelengths.
The heat, smoke, and flame are sensed using a focal plane array (imager). The detector includes
provision for the connection to a source of power, signaling, and optional remote-control circuits. Additional
functionality is permitted to be incorporated as part of the detector assembly.
1.3 This standard covers detectors intended for open area protection and for connection to a compatible
power supply or control unit for operation as part of a fire alarm system.
1.4 This standard does not cover the following:
a) In the United States (1) – (7):
1) Single pixel/integrating (non-imaging) flame detectors;
2) Wildfire detectors;
3) Control units to which the detectors are intended to be connected that are covered by the
Standard for Control Units and Accessories for Fire Alarm Systems, UL 864;
4) Self-contained single and multiple station smoke alarms, not intended for connection to a
system control unit, that are covered by the Standard for Smoke Alarms, UL 217;
5) A gas and vapor detector or sensor incorporated as a part of a smoke detector assembly,
and covered by the Standard for Gas and Vapor Detectors and Sensors, UL 2075;
6) Commercial-residential detectors not intended for connection to a system control unit that
are covered by the Standard for Smoke Detector Monitors and Accessories for Individual
Living Units of Multifamily Residences and Hotel/Motel Rooms, UL 1730;
7) Detectors for monitoring the smoke density within flues or stacks.
b) In Canada (1 – 6):
1) Single pixel/integrating (non-imaging) flame detectors;
2) Wildfire detectors;
3) Control units that are covered by the Standard for Control Units and Accessories for Fire
Alarm Systems, ULC 527;
4) Self-contained single and multiple station smoke alarms that are covered by the
Standard For Smoke Alarms, ULC-S531;
5) A heat detector incorporated as a part of a smoke detector assembly, and covered by the
Standard For Heat Actuated Fire Detectors for Fire Alarm Systems, ULC-S530 and/or when
part of a multi-criteria smoke detector;
6) Detectors for monitoring the smoke density within flues or stacks.
1.5 These requirements also cover all remote accessories that are intended to be connected to a
detector.
