In the event of an actual alarm, the system will sound a loud siren or bell; it may then immediately communicate to a Central Monitoring Station, and state the nature and exact location of the emergency so the proper authorities can be despatched.

Intermittent tone siren or bell

typically indicates that a fire has been detected

Steady tone siren or bell

Typically indicates that a burglar has been detected.

Your neighbour also has "panic buttons" that he can use to activate the police emergency alarms, should the need ever arise.

How You Can Help

If you hear an intermittent tone siren/bell (fire emergency)

Be aware of your neighbour’s fire escape plan and his family’s common meeting point outside the home.
Help in anyway you can (with ladders, etc) with the safe evacuation of your neighbour’s home. Be aware of which windows, especially those of small children.

If you hear continuous siren/bell (police emergency)

Do not leave your home to go and investigate
Look for open doors or broken windows
Jot down the description of any strangers
Note the colour, make and license number of any unfamiliar car or truck
If the sirens stop after sounding for less than a minute, call your neighbour. He may have accidentally set off his own alarm
If the sirens sound for longer than one minute, call the police
Never become physically involved
