Alarm Systems
Why should I have a security alarm system?
Having a security alarm system may decrease the chances of a burglary. Even if the alarm system does not keep a burglar from breaking in, it may cause the burglar to stay a shorter amount of time.
What Should a Security Alarm System Include?
Most systems rely on a combination of contacts placed at doors and windows and motion sensors.
It is best that all exterior potential points of entry have contacts that sense when they are open. Glass break sensors are also available and recommended.
The basic elements of a standard home security system include:
Control panel:
- This is where the system wiring terminates, the backup battery is located and where it is connected to the phone lines if it is a monitored system.
Keypad:
- This is where the system is armed and disarmed.
Siren:
- Located inside and outside the premises.
Inside motion detector:
- These sense changes in a room caused by human presence. Special motion detectors are available for people who have pets.
Door and window contacts:
- This sounds the alarm when the door or window is opened (and the system is on).
A central monitoring station (Company):
- If the system is monitored, and the alarm is set off, the control panel sends a message to a central monitoring station, which is manned 24 hours a day.
Additional items that can be added to the basic system are:
- Smoke detectors
- Glass break detectors
- Panic buttons
- Camera Surveillance to allow monitoring and/or recording inside or outside your property.
Monitored systems typically work as follows:
- The security system senses something.
- If the alarm is not deactivated the security system sends a message to the monitoring company over telephone lines.
- The monitoring company receives the message and verifies the alarm, generally by placing a phone call to the home. If they do not receive the proper password or do not receive an answer, they call the nominated contacts or patrol service is dispatched.
Non monitored systems typically have on-site alarms and/or flashing lights. It relies on neighbours to call police.
Neighbours or passersby should never investigate an alarm themselves.
With an unmonitored system, it is best to have a combination of strobe lights and alarms. They should be located on the street side of the property and in an inaccessible spot as possible. It is best to discuss the installation with your neighbours and to place the siren and flashing light on the house where it can be easily seen.
