Alarms and Monitoring Systems

A loud alarm is certainly a way to let the world know that something is going on. However, we are so used to hearing alarms go off - or on and on and on - that many people just ignore them. However, if that alarm also sends a signal to a monitoring station, you know there will be a response.

Connecting your alarm - whether it is a business alarm, home alarm, fire alarm or personal distress alarm - to a 24-hour back-to-base monitoring system means action. Not only is a problem detected, but a response is initiated that may save your property, your livelihood or even your life.

Alarm monitoring systems are usually made up of a number of components.

The detection device

Depending on the purpose of your alarm monitoring system, the detection device can detect movement; opening of windows or doors; sounds, such as glass breaking, drilling or explosives; a gas leak, temperature rise or smoke. A personal distress alarm is generally set off by the person wearing the alarm in times of need.

Detection devices include:

• Passive Infra-red detectors and microwave technology to detect movement.
• Magnetic reed switches to detect opening of doors and windows.
• Panic or duress buttons used in an emergency.
• Glass break detectors which sense sound frequencies.
• Vibration sensors to detect breaking glass or forcing of doors and windows.
• Photoelectric beams which cover a fixed area and are ideal for perimeter protection.
• Smoke, fire and heat detectors.

The control panel

The detection device is linked (either by wire or wireless) to the control panel. The control panel receives a signal from the detection device, and sets off an audible or silent alert. The control panel links all the parts of the security system. It generally includes a keypad console, which allows you to turn the alarm on and off. This can done using a Personal Identification Number. Businesses may choose to give individuals their own PIN so they can keep track of who is coming and going and when. The control panel can also be programmed to run regular tests of the system.

The signal

This is the alert. It can be an audible siren and/or a silent message that is relayed to the monitoring station. Given that audible alarms are limited in their effectiveness, they are often linked to a monitoring station to ensure a response.

Transmitting the signal back to base

The signal transmits a message back to base usually via your existing telephone service. Digital diallers are fitted to the control panel to activate a call to base using your telephone line. Some security companies have access to a Telstra security network that uses the existing telephone line without making a call - a duplicated transmission path is used.

As there is always a possibility that burglars will cut your phone line, these transmission options are usually backed up by cellular or radio transmission options. Most alarms also have battery back up. Some security companies also offer Internet-based connections, which promote faster and more reliable signalling and response.

The response

The response from the monitoring station will depend on the alarm system you have set up. The monitoring station may alert police, ambulance, fire brigade, security personnel, a technician, or an authorised person.

Up to standard

Alarms should comply with Australian Standards 2201. Central Monitoring Stations must be constructed and fitted out in accordance with Australian Standards AS2201.2
Monitored alarm systems must also include Austel approved dialler and wiring and the installer must be licensed.

ASIAL conducts independent inspections of central monitoring stations to ensure that they comply with Australian Standard 2201.2-2004 (Intruder Alarm Systems - Central Stations).

Maintaining your alarm system

When looking for a monitoring system, make sure that the security company provides:

• Regular system testing - signals are sent regularly, usually daily, to your system to verify that it is working.
• Maintenance - you want to have at least annual cleaning and maintenance of your system to make sure it is performing at its best.

Likely costs

The costs of the system will depend on the level of security and monitoring, the sophistication of the equipment and technology and the type of response required. You can expect most alarm monitoring systems to cost between $900 and $1600. This may include costs for set up, equipment, warranties, and a monthly fee for monitoring. Check that quotes include all costs, as well as any costs associated with sending out a response team or answering a false alarm.

There are also competitive prices available for equipment and monitoring services that may be suitable for your needs.

Also, check out your insurance policies as you may be entitled to a discount on you insurance premium if you upgrade your security.
