Installing or Replacing the Battery

The battery is not required for normal operation when the RTS receives adequate natural or artificial
light. The battery can be used during installation (start assist). Note: A battery is provided with the
sensor. The battery has enough power to run the sensor for 5 years without light.
1.
Remove back plate of the TR9277-EO by pressing a screwdriver into the
slot key on the bottom of the sensor enclosure and pull the body away
from the back plate. The top of round battery cover just snaps
completely out to allow placement of the battery.
2.
To remove old battery: Using a small flat head screwdriver or pen as a
lever, insert pointed end under the clear plastic battery retaining clip's
edge and pop the clip off.
3.
Install or replace the battery in the clip with a new CR2032 coin cell
battery insuring the positive side (+) will be facing up.
4.
Align the two straight edges of the retaining clip with the battery holder
and press the clip in with your finger.

Guidelines for Installing Wireless Devices

Careful planning is needed when locating the receivers and transmitters based on the construction
materials in the space and possibility of tenant's furniture disrupting the transmissions.
The CO2 sensor should be installed in the space where the receiver is mounted and connected to the
temperature control equipment however the signal will travel through material barriers. Refer to the
tables below for range considerations with building materials that reduce the radio signal power.
