TrueAlert ES Addressable Indoor A/O Notification Appliances Installation Instructions
Cautions, warnings, and regulatory information
IMPORTANT: When the notification appliance emits light or sound, it indicates the possibility of an emergency situation that requires
immediate attention of all occupants.
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.
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.
