In a typical installation, the motion detector is mounted indoors in a  
corner or on a wall between six and eight feet high. The sensor will  
monitor the infrared level in its detection pattern. If the level increases  
or decreases rapidly (as when a person or animal moves through the  
area) the transmitter triggers, sending an alarm signal to the receiver.

IMPORTANT !!!  
Linear radio controls provide a reliable communications link and fill an important need in portable wireless  
signalling. However, there are some limitations which must be observed.  
REPLACE THE BATTERY WITH  
A FRESH 9-VOLT ALKALINE  
OR LITHIUM BATTERY  
(PLUS SIDE UP)  
For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as  
Part 15 devices. As such, they have limited transmitter power and therefore limited range.  
A receiver cannot respond to more than one transmitted signal at a time and may be blocked by  
radio signals that occur on or near their operating frequencies, regardless of code settings.  
USE ALKALINE  
OR LITHIUM  
BATTERIES ONLY  
Changes or modifications to the device may void FCC compliance.  
WALK ACROSS THE DETECTION  
PATTERN AND VERIFY THAT  
THE RECEIVER ACTIVATES  
Infrequently used radio links should be tested regularly to protect against undetected interference  
or fault.  
A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale  
distributor or dealer, and these facts should be communicated to the ultimate users.
