Usually ALEAN Security provides two kinds of alarm systems for security alarm projects.
Distribution alarm system and Bus alarm system.
They are used in different security protection projects base on the program scale.
For small project which requires less detectors, such as shop, home, office, etc.
Base on economic consideration, we suggest you to choose the distribution alarm systems.
But when you choosed the distribution alarm system, the distance between the alarm control panel and each detector requires less than 200 meters. If too long distance, the voltage and signal will be effected.
For big projects which needs many detectors, such as industry park, hospital, supermarket, etc.
We suggest you to choose the bus alarm system.
The bus alarm system has no strict limit for the distance between alarm controller and detectors, if too long distance, such as more than 1200 meters, we will suggest you to add a signal amplifier.
Here, we will use photo beam sensor as an example, make two diagrams for you to understand more about the distribution alarm system and bus alarm system.
(Attention: The detectors can be photo beam sensor, laser detector, infrared barrier, electronic fence, vibration optic fiber, PIR detector, smoke detector, panic button, etc. )
