Wireless home alarm system control panel A house alarm. A security alarm is a system designed to detect intrusions, such as unauthorized entry, into a building or other areas, such as a home or school. Security alarms protect against burglary or property damage, as well as against intruders.
The alarm transmission methods covered under UL 365 can be categorized under standard line security or encrypted line security. The systems are required to operate within the limits of Class 2 remote control and signal circuits as defined by the National Electrical Code, NFPA 70.
A control panel is implemented to arm and disarm a home security system. The control panel is the main connection to the alarm company monitoring a home. It typically features a touchpad or buttons to easily maneuver the system, and some newer systems also feature voice control or wireless remotes (key fobs).
An alarm monitoring center, central monitoring station (also known as "CMS" or wholesale central station), or alarm receiving center (also known as ARC) [1] is a company that provides services to monitor burglar, fire, and residential alarm systems. The Central Monitoring Station may also provide watchman and supervisory services.
Dual-loop allows the burglar alarm control panel to read the values of end-of-line resistors for the purpose of telling a zone's status. For example: if an alarm system's software uses 2K ohms as its non-alarm value, an inactive detector will give a reading of 2K ohms as the circuit is passing through just one resistor.
When used as part of a security system, the electronics in the PIR typically control a small relay. This relay completes the circuit across a pair of electrical contacts connected to a detection input zone of the burglar alarm control panel. The system is usually designed such that if no motion is being detected, the relay contact is closed—a ...
