| Basic
facts: |
| Communicating devices as used in
security systems can be divided into the following categories
based on : |
|
|
Tape dialler:
The oldest form of communicator was based on the old
8-band cassete player. A recorded voice message was transmitted
to the Garda Siochana: "Garda, Garda, Garda.....Alarm activation
at the house of Mr Jones, etc, etc"
These devices can no longer be used to report an alarm activation
instead the alarm report must be sent to an Alarm Monitoring
Centre where in turn it is passed on to the Gardai. |
Digital
Voice message transmitter:
This communicating device transmits a pre-recorded
voice message to a list of standard telephone numbers pre-programmed
by the alarm installer. It is normally used to contact family
members or neighbours who can come and check your house......

Digital message transmitter:
Known in the trade as a "digi", this
device is a separate unit installed by the alarm installer
as part of the initial system or is added at a later stage.
Special digital signals can be transmitted over a standard
telephone line to a recieving unit housed in an Alarm Monitoring
Centre. These signals are generated by the alarm system detecting
an activation from:
---a smoke detector
---door/window magnetic contact and/or shock detector
---a panic button
---a movement detector, etc
The Alarm Monitoring Centre on receipt of these digital signals
would then inform the proper authorities/emergency services,
ie Garda Siochana, Fire service, Ambulance service.
Note: This is the
normal type of communications system as used in alarm systems
today.

Upload/Download
communicators:
With the latest advance in communication techniques
it is now possible for the alarm installation company to carry
out remote programming of an alarm system by using an Upload/Download
communicator. Unfortunately these devices are either part
& parcel of the control panel or are designed to connect
to a certain manufacturer's control panel(s).
Some Upload/Download communicators have special features which
allow the Alarm Monitoring Centre to listen-in or have a 2-way
conversation with the person(s) in the house. These features
can play a very important role in situations where the alarm
activation should be verified ie with the listen-in feature
the intruder can be heard moving around the house. In a medical
alert situation, the Alarm Monitoring personal can communicate
directly with the injured person, determine exactly what the
problem is and inform the proper emergency service.
