Alarm systems can be installed to emit a local alarm using a bell or siren,and they may be connected via a common carrier network (i.e. telephone lines) to a monitoring station which dispatches the appropriate response authority (police, private guard, fire, medical) when the system transmits a signal. In addition to the response authorities being dispatched, a monitored system may also emit a local siren when activated. A “local only” system does not in itself dispatch police.
In order to receive response,you must either rely on a neighbour calling the police (in the case of a local system) or you must have the system monitored (24hrs) by a monitoring station. For this service, a nominal monthly fee is paid and can be arranged through your alarm installation company. In most, if not all municipalities, alarm systems may not be connected directly to the police as a result of municipal by-laws. |
