MOUNTING GUIDELINES
GENERAL GUIDELINES
In addition to NFPA 72, use the following location guidelines to optimize performance and
reduce false alarms. Refer to Figure 9.
• Place ceiling-mounted smoke detectors in the center of a room/hallway at least 4
inches from walls and partitions. If a ceiling is sloped, peaked, or gabled, place the
detector 3 feet from the highest-point. If mounting to suspended ceiling tile, the
tile must be secured with an appropriate fastener across ceiling panel supports.
• Place wall-mounted smoke detectors at least 4 inches below the ceiling.
• Mount smoke detectors on a firm, permanent surface.
• Place in environmentally-controlled areas with a temperature range between
40° and 100° F (4.4° and 37.8° C) and the humidity is between 0 and 90% non-
condensing.
