How the Alarm Monitoring System Works and keep
your insurance company happy
Burglar alarms are in electronic form. A simple set-up of an
alarm system includes a sensor that is connected to one or more
control units. When the sensor is triggered, the control unit
seeks for a way to announce the alarm.
Basically, alarm systems can either be
hardwired or wireless. The wired systems are usually used with
sensors, smoke detectors for example, which demand power for
reliable operation. Wired types come with the advantage of
detecting tampering. However, wired systems are expensive to
install. On the other hand, wireless alarm systems are easier
to set-up. Instead of wires, they utilize transmitters.
Wireless systems require constant supervision and maintenance
to ensure efficient operation. If for example, the sensors or
batteries have not been constantly checked, the system may not
perform at its peak.
Alarm monitoring is employed in systems with a
remote alarm output. In such systems, the control panels are
connected to predetermined monitors, and they are configured in
various methods. One includes a direct connection of the system
to a responder, or a central station, such as a police
quarters. However, this kind of configuration is becoming less
popular because it is expensive. Direct monitoring connections
can usually be found only in Local Government institutions,
State, or school campuses where there is a dedicated
security.
More conventional alarm systems make use of
Public Switched Telephone Network, or PSTN. This configuration
features a digital phone dialer unit which will dial the
central station, which in turn will announce the alarm. The
monitoring system can identify the physical location of the
sensor that has been triggered with the use of certain
programmed encoders. Most alarm control panels are designed
with backup dialer ability that can be used when the primary
PSTN route is not functioning well. The secondary dialer can be
connected to a separate phone line (or an encoded radio, mobile
phone, or internet interface gadgets) to entirely evade the
PSTN. This is because if the primary lines have been tampered,
alarms could still be raised via the redundant dialers and
early warnings of pending problems can be advised.
In situations where the building is remotely
located, PSTN service may not be feasible and channeling a
direct line may be too expensive, there is still a way so your
security can be monitored. And that is by using wireless phones
or radio networks as the principal communication line. The use
of the Internet as a main communication method is still very
controversial within the alarm monitoring business. This is
because an alarm signaling method needs to observe urgency and
immediacy, and the authorities are doubtful of the quality of
service of public internet.
When monitored, the alarms and speaker phones
permit the central station to communicate with the owner, or
even with the intruder. For monitored burglaries, the speaker
phones let the central stations to convince the prowler to back
off and give up as police units have been sent off.
Considering some factors, such as the location
of the zone triggered and time of the day, the alarm monitoring
center may perform various actions automatically. Some
instructions they may initiate include calling the police
stations, fire department or ambulance. They may also choose to
check if the alarm is true. Some systems come with video
surveillance to capture the actual acts of intrusion or other
emergency cases on tape.
