Running wires over long distances or over areas that are concrete or asphalt can
cost thousands of dollars and may require time-delaying digging permits. And
then the wiring eventually goes bad or is accidentally cut and you have to do it
all over again. A cheaper and faster solution is to install a MURS Callbox.
The MURS XT Callbox works with our other MURS
radios and it provides long
range, 2-way voice communication
from the fixed location of the Callbox to any of your
other MURS intercom units. It
has a range of up to one mile or more with an optional external
See the applications and other products available for MURS in the
MURS Product Brochure (requires the free Adobe PDF Reader to view and print).
This heavy duty outdoor intercom is designed for
construction sites, golf courses, hotels/motels, airport parking
lots, gated entrances, manufacturing, college campuses,
hospitals, receiving docks, amusement parks, resorts, locked
entrances, farms, ranches, warehouses, campgrounds, parking
lots, delivery doors, and any other application that needs two
way communication for safety or convenience.
no need for extensive wiring, trenching, remodeling, or
installing dedicated phone
lines with expensive monthly fees since the MURS Callbox is completely wireless.
This callbox can operate on 6 D-cell batteries (alkaline or Ni-Cad
rechargeable). However, it comes programmed with the
battery-saving Auto Turnoff feature disabled so we recommend using an external
power source. This way your callbox will be available to receive calls and the
gate opening command at any time instead of just when someone presses its call
The MURS Callbox has two modes of power consumption.
In Automatic Turn-Off the unit turns itself off after a programmed amount
of inactivity (up to 4 minutes). It can only be turned on again by pressing its
Call button on the Callbox. In this mode it cannot receive calls from
other intercom or handheld radio units. It can only make calls and then other
units can respond.This is what the unit is programmed for and we recommend buying the optional power supply so you can open the gate even if no one presses the Call button.
In Normal mode, the unit does not turn itself
off and the MURS Callbox can not only make calls, but receive
them as well. This mode consumes the largest amount of power and
should only be considered if an external source of power is available. If an external source of power is used, the internal batteries
can be installed as a back-up against loss of power.
If you use the MURS Callbox Outdoor Intercom along with the MURS
, or the
MURS J-V110 Two-Way
(see pictures), the
Callbox can be used to remotely control gates, magnetic door
locks and other devices.
Callbox has a single 1-Amp switch output that can be activated
when the Callbox receives a unique 2-Tone encode signal that the
MURS Commercial Intercom and MURS J-V110 can send.
A 2-Tone encode signal can also be used to activate the
Listen-In feature of this Callbox, which lets you listen to what's happening
around the Callbox for up to 30 seconds.
This Callbox has a switch output that can be used to open or close a
gate, turn on a light, sound an alarm, or any application where remote
control of an On/Off switch is required. The switch can be programmed to
operate in several ways:
- On/Off Code: The switch will close when a preprogrammed code is
received, and open when it is received again. The switch will also open by
itself when the Callbox's preprogrammed Automatic Turn Off feature is
- Switch On When Called: The switch closes when the callbox first
receives the call and it remains on until its Talk button is pressed, or a
programmable timer expires (1-255 seconds).
- Switch On When Callbox In Use: The switch will close when the
Callbox first sends or receives a call and remains closed until a
preprogrammed timer expires.
- Switch On When Active Includes Turn-Off Code: Switch closes when
the Callbox sends or receives a call with the added ability to open the
switch when the Callbox receives a preprogrammed code.
- Momentary Close: Switch will close for 1-255 seconds when a
preprogrammed code is received.
- Alternate Open and Close: Switch will toggle between open and
closed when it receives a preprogrammed code. The Callbox transmits a single
beep when open and a double beep when closed.
The MURS Callbox with Gate Relay also has a Sensor Input that
allows it to also operate as a motion, gate
entry, tamper or vehicle detection device. It will send a
tone alert when optional switch/sensor status
changes. The Callbox will send a warning tone when a change in
the Sensor Input is detected. The Sensor Input will respond to
an OPEN or CLOSED switch.
The Listen In feature allows remote activation of the callbox's transmitter when a unique 2-Tone code is received. This enables you to listen in to the area around the callbox for a period of up to 30 seconds.
The MURS Callbox is housed in a fiberglass
enclosure with a stainless steel faceplate that includes
tamper-resistant fasteners and a concealed antenna making it
perfect to withstand harsh elements.
Since this callbox operates in the MURS
frequencies, no FCC license is required.

"We are utilizing the call boxes at three
vehicle entry gates onto the property. Two of the locations are
equipped with badge readers that operate the gate. One of the
locations is a Visitors entrance where the person entering interacts
with our Security via the call box.
Our old system was done with all underground wiring and we were
experiencing many problems with broken underground conduit. The
wireless solution was the way to go for us. The system was very easy
to install especially with the additional functionality that I
wanted. The technical customer support was excellent. They seemed to
care a great deal about my project being successful which left me
with the confidence of knowing that If I ran into any problems that
all I needed to do was pick up the phone. We have not experienced
any problems with our system."
Matthew A Razzano, Gap Inc. Direct, Groveport, OH
"We use the callbox to talk to visitors and open the entrance
gate from the office and portable radios (walkie-talkies). We can
talk to visitors wirelessly and open the gate wirelessly from the
office or the portable radios. Personnel can be anywhere on our
40-acre site and still communicate with the gate and open it.
Physical installation was simple and the instructions are good.
Technical support is very good. The programming is a little tricky
until you understand how to do it."

"We use your callbox on the outside door of our plant so truck drivers can call in and identify themselves and we can then let them in remotely through a security door. Everything about the callbox works for our application, but we especially like the how we can use a wireless handheld unit to remotely manage the entrance when we have to leave the office to go to other parts of the plant."
