The liquid detector AFA 11 BAS is the successor product of the oil/water alarm unit 3 with burner connection kit.
The liquid detector AFA 11 with burner connection kit consists of a control unit with visual/audible alarm, Test and Acknowledge keys, a relay output and a photoelectric probe with 10 m connection cable. Cable and connector for connection of burner and boiler are fully wired and ready to be connected. In the event of an alarm, the unit triggers visual and audible alarms and switches off the burner. The audible alarm can be muted with the Acknowledge key. The visual alarm remains active until the leak has been removed. The burner then resumes operation. The Test key allows you to simulate an alarm condition in order to perform a function test. Alarm units with the EnOcean-ready label can be integrated into your existing building automation systems, for example, AFRISO smart home, at a later point in time. To do so, plug the EnOcean® wireless module into the EnOcean® interface (PCB of the device). The AFRISOhome gateway in conjunction with additional AFRISO smart home products with EnOcean® wireless technology allow you to configure a whole range of fully customisable, extensible features for the protection of plants and buildings. Power outage alarm: An optional 9 V battery can be connected so that an audible signal is triggered in the case of power outage. The audible signal cannot be acknowledged and is disabled once power is available again.
