The MURS Alert transmitter is a passive infrared (PIR)
detector that can be used to detect people, vehicles or
large animals at selected locations. The PIR sensor will
detect movement of objects up to 80 feet in front of the
transmitter box. When a person, vehicle or large animal is
detected, the MURS Alert will transmit a signal.

When an target is detected by the MURS Alert, an alert
signal will be sent to the M538-HT or M538-BS MURS
radio. (See page 4 for more information about alerts)

Instructions:

When you open the MURS exterior case
(fi gure 1-1), you will see an antenna
(fi gure 1-2), a battery pack and the
PIR unit. Attach the antenna to the
antenna jack (fi gure 1-3), located on
the top of the case.

Power Supply:
The MURS Alert transmitter is powered
by 6 AA batteries. For best results, we rec­ommended that you use good quality
alkaline batteries. When replacing bat­teries, do not mix old and new batteries
together. The average life of the bat­teries is about 6 months under normal
conditions. Conditions affecting battery
life include use of the product in high
traffi c areas, and using product in a cold
climate. If you live in a cold climate, it
is recommended that you put in new
batteries at the beginning of winter.

Installation:
In order for the sensor to detect properly
it is recommended that the transmitter be
mounted on a tree or post about 20 feet back
from the area to be monitored and about 3
to 4 feet off the ground. If you want to detect
smaller animals, the sensor can be mounted
closer to the ground. (See fi gure 2)

Alert Signal:
The MURS alert transmitter has 4 different
alert signals. The alert signal will repeat the
location of the transmitter. The signal will
be a voice saying “Alert zone one,...” “Alert
zone two,...”, “Alert zone three,...” or “Alert
zone four.” If you have more than one trans­mitter, you may wish to change the alert
from the default setting (Alert zone one…)

to one of the other alerts. This can be done
by changing the position of the switch,
located on the radio transmitter.

slide switch. If the switch is all the way to the top, it will be zone one, the other zones will
be located in order from the top.

Operation:
A. The factory-set default for the transmitter is Channel 01 Sub-channel (CTCSS) 01.
B. Channel selection. The MURS Alert transmitter is capable of transmitting on any of the

6

5 MURS channels. To select the proper channel, locate SW1 (fi gure 4-

) and set it to the
appropriate channel, If SW 1 is set to “0” it will default to channel 1.
C. Sub Channel (CTCSS) selection. To select the proper CTCSS locate SW2 and SW3 (fi gure
4-7). SW2 is labeled 0-3, SW3 is labeled 0-9. SW2 represents the fi rst digit in the CTCSS
and SW3 represents the second digit in the CTCSS. Example for CTCSS to be set at 38, SW2
must be set at 3 and SW3 must be set at 8. The are 38 different CTCSS combinations, if the
CTCSS is set at 39 or 00, no sub code will be in use.
