The next level would be to add a speech dialler to the alarm system that interfaces between the alarm system control panel and the telephone line, upon activation the speech dialler will contact up to four nominated key-holders making them aware of the alarm condition.

Police response to alarm systems can be achieved via several methods but all are monitored by a NSI approved monitoring station who pass the activation to the Police subject to the activation meeting the requirement for confirmed signalling, this is something that would be discussed in detail should the required or be a stipulation of the insurer.
