Your burglar alarm is connected to a monitoring station by a communication channel. That channel can be via a telephone network, the internet, radio signal or cellular signals. A key to reliability of the alarm system is that the alarm transmission channel is reliable and any tampering with this communications channel is detected quickly and investigated. This is the basic premise of line security.
Line security is a very important component of your burglar alarm protection program. If the burglar can simply cut the wires that connect your alarm to the communications system, the alarm is not an effective protection system for your business.
Line security requires a two-way signal path. The alarm monitoring facility must be able to poll your system and receive a response that the line is intact. Line security standards call for the line to be tested and verified at intervals of every 200 seconds.
There is a critical difference between line supervision and line security. Line supervision requires a communication check every 24 hours versus the every 200 second check that constitutes line security. The difference in time lapse between signals means line supervision is not the equivalent of line security.
Line security is important to you as there may be underwriting expectations related to the type of alarm system present at your facility. The type of alarm system required can vary based on values present, type of safe or vault present and a number of other factors. While the term "line security" may be used inaccurately by some people in the business, it has a very specific meaning to your underwriter.
