Techniques and systems are described for creating and operating a vibration triangulation network. The network can include vibration sensor devices placed in a building, such as a store or a house, which are able to pinpoint the location of a target, e.g., person, animal, etc., through triangulation. A described technique includes receiving vibration notifications from vibration sensor devices, determining a location of a target within the building based on at least a portion of the vibration notifications and a vibration sensor map associated with the building, and triggering an alarm event based on a detection of the target.

A component 14a for a fire protection system 100 includes communications circuitry configured to communicate with another component 14b-14d of the fire protection system 100. The communications circuitry may allow a portable tool 20 to communicate with the other component 14b-14d via the component 14a.

A method, an obstruction detecting device, and a non-transitory machine-readable storage medium are provided for detecting an object obstructing access to a feature of a building. A distance sensor connected with an obstruction detecting device emits a signal. The distance sensor receives a reflection of the signal from an object. A microcontroller of the obstruction detecting device, which is connected to the distance sensor, determines a distance from the distance sensor to the object based on an amount of time between the emitting of the signal and the receiving of the reflection of the signal. When the determined distance is less than a threshold distance, indicating that the reflecting object is obstructing access to the feature, the obstruction detecting device provides an alarm.

Systems and methods are provided that can include receiving a plurality of cause and effect rules for a security system that protects a secured area, simulating a plurality of cause and effect rules responsive to user input identifying an emergency event in one of a plurality of zones of the secured area, and during simulation, displaying on a graphical user interface a first indicator that identifies a first output of a first of the plurality of cause and effect rules within a first of the plurality of zones.

An image of at least a portion of a room may be received, the image of the room comprising an image of a sensor mounted in the room. At least one optical parameter related to the image of the room may also be received. A distance may be determined between the sensor and a camera that captured the image of the room, wherein the determination of the distance is based at least in part on the optical parameters and on known physical dimensions of the sensor. A sensitivity requirement of the sensor may be determined, based on the distance. The determined sensitivity may be sent to control logic of the sensor.
