Our
Wireless Call
Box Outdoor Intercoms have way
more capabilities than we have chosen to highlight on their respective product
pages. In fact, there are several models of this product with a rather
overwhelming array of capabilities. Most people don't need all the functionality
these units have so we
have simplified them to meet the needs of the largest percentage of the
population. If you just need a basic intercom-style callbox, we recommend you
stick with the basic configuration as we have defined it on these product pages.
However, for those of you who have special requirements, we want to give you
a rundown of what you can do with a Callbox. Here are some of the capabilities
you can get:
- If you already have existing two-way business radios the Callbox can
programmed to be compatible with almost any brand of VHF or UHF business
band radio (you need to order either the UHF or VHF model depending on the frequency range you use.) This is a simple change in its internal programming and we do
that for you as defined by your requirements. Many of the frequencies used
will require an FCC license. The MURS frequency is license-free.
- If the distance you need to cover is greater than the range of the
wireless call box, you can extend range by adding an external antenna. In the
FCC-license frequency range, you can also get radio repeaters to
extend this range even more.
- There is an optional solar power unit you can add to your Callbox so that
it can
run for several days on a single day of sunshine.
- An optional external strobe light option can be added to the Callbox and
you can turn this on from a remote location.
- There is a version of the Callbox that has the ability to
store a voice message that is played when someone presses its button. This could
be a message that gives the caller specific instructions on what to do. This unit can also send a different voice message alert to the monitoring
central location or portable radios. This message could give the callboxes
location or it could be an emergency message of some type.
- If you have several callboxes in use and you need to know the location
of the unit calling in, then the Callbox can transmit a unique numeric
identifier to a radio that has the ability to decode this identifier.
This is like having a telephone with Caller ID capability. Some of our
Commercial Intercom and
Two-Way Radios have the decode ability and they can be
programmed to the same frequencies as the CallBox.
- A couple of versions of the Callbox let you add a motion detector or some other detection device
so you can be alerted when that detection device is activated. Depending on
the model chosen, they send a tone alert or a custom voice alert when the detection sensor
status changes. If this alert is not immediately answered, the alert
message is resent up to 5 times. You can also use an external sensor to automatically put
the unit into full power mode when someone is detected near the box. This will
allow you to make a call to it.
- If you want to listen to what’s happening around the
call box, some models let you use the
callbox microphone to monitor the sound around it.
- All models have a low battery alert or
external power fail tone that is sent to the monitoring portable radio or base
intercom.
- A paging feature allows selective calling of
individual boxes or a group of callboxes simultaneously.
- The busy channel feature prevents someone from
transmitting if someone else is using the radio channel.
- One model has an entry keypad with built-in relay lets people enter a
code at the call box to open a gate or door. Remote opening of the gate by
monitoring personnel can still happen also.
So if you have a need for any of the capabilities on this page, call us and
we will work a solution and pricing for you.
