Rate of Rise Sensor
(continued)
Mounting instructions:
Use the mounting tabs on the box (screws not provided)
OR the included Dual Lock adhesive strips to attach the
Rate of Rise Sensor to the ceiling. The best location for
the sensor is at a high point where heat will build. The
recommended mounting height is 10ft. The first sensor
near a wall should be placed no more than 25ft away
from the wall, additional sensors away from the wall can
be spaced at 50ft (see fig.1)
Sensors should be mounted no less than 4” from any
corner and no more than 12” from ceiling (see fig. 2)
Mounting is possible above the height of 10ft but spacing
between sensors and walls will decrease with additional
height. (see fig. 3) or contact tattletale for specific mount
-
ing instructions).
When mounting sensors on ceilings with exposed joist al
-
ways mount sensors below, not between joist. (see fig.4)

NOTE:
Do not mount sensors where they can be
directly exposed to rain or snow.
Do not mount sensors in the direct path of hot or cold air flow.
These conditions can cause alarm events and/or adversely
affect the sensor’s sensitivity.
