IMPORTANT: When the notification appliance emits light or sound, it indicates the possibility of an emergency situation that
requires the immediate attention of all occupants.
LOCATION REFERENCE: Location and quantity of appliances required must conform to the applicable local standards and
guidelines (the National Fire Alarm and Signaling Code (NFPA 72); ULC Standard CAN/ULC-S524, Installation of Fire Alarm
Systems; the appropriate model building codes, etc.) and specific requirements of the Local Authority Having Jurisdiction (AHJ).
These notification appliances are not intended for installation within hazardous locations as defined by the National Electrical
Code (NEC) or NFPA.
SAFETY: Always install, maintain, and test notification appliances within their specifications. Failure to follow all safety
precautions and instructions may result in loss of life and property due to non-functioning notification appliances. Some
notification appliances use high voltage. To avoid electrical hazards and avoid damage to appliances, make sure that the
electrical power for the notification appliance circuit is disconnected at the control panel before installing, repairing, or internally
adjusting any notification appliances. Even with electrical power removed, some notification appliances (such as visible strobes)
store a high voltage charge. The high voltage can cause injury resulting in death from electrical shock. DO NOT TOUCH
EXPOSED CIRCUITRY.
