Smoke And Heat Detector Locations - Interlogix ZeroWire ZW-6400 Reference Manual

Smoke and heat detector locations:

Selecting a suitable location is critical to the operation of smoke alarms. Figure 2 shows
some typical floorplans with recommended smoke and heat detector locations. Use these
location guidelines to optimize performance and reduce the chance of false alarms:
 Before mounting alarms, program (learn) them into memory and do a sensor test from the
alarm's intended location to ensure good RF communication to the panel.
 Locate the alarm in environmentally controlled areas where the temperature range is
between 40 and 100°F (5 and 38°C) and the humidity is between 0 and 90%
noncondensing.
 Locate alarms away from ventilation sources that can prevent smoke from reaching the
alarm.
 Locate ceiling mounted alarms in the center of the room or hallway, at least 4 in. (10 cm)
away from any walls or areas.
 Locate wall mounted alarms so the top of the alarm is 4 to 12 in. (10 to 31 cm) below the
ceiling.
 In rooms with sloped, peaked, or gabled ceilings, locate alarms 3 ft. (0.9 m) down or away
from the highest point of the ceiling.
 When mounting to suspended ceiling tile, the tile must be secured with the appropriate
fasteners to prevent tile removal.
Note: Do not mount the alarm to the metal runners of suspended ceiling grids. The metal
runners can draw the magnet's field away from the alarm's reed switch and cause a false
tamper alarm.
