Expanders increase the number of inputs and outputs of the intruder alarms. They allow you to increase the number of wired zones used with your hardwired system. This can be very important if you are setting up a major security system for a large home or business.
Since some of the wire runs may be too long and difficult, the expander can be placed up to 200 meters from the alarm device and sensors can be added to this device.
Once a device zone is triggered, a text message will be sent to the alarm users, indicating the zone and device number.
The A570 alarm panel can be connected to up to 5 expanders, which can provide up to 100 wired zones that makes it sufficient even for very large projects.
This device connects to the alarm system via RS485 communication.
Another product is the output expanders that can be used to remotely control several electronic devices.
