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.
SNAP DETECTOR ONTO BASE
AND REPLACE CASE SCREW
