Up to four magnetometer sensors are mapped, at the access point, such that the detection
from a sensor is routed to an interface card. Each interface card can cater for a maximum
of 4 sensors along with an optional master fault output.

Detector Interface Card
Figure 22 - Diagram of a Typical WiMag System - Small System
The WiMag Loop Detector Replacement Card also includes two PoE enabled ports, which
will provide power directly to two Access Points (depending on configuration), without the
need for an external power supply nor a PoE switch. However, this does mean the 24V
supply to the backplane must not be derived directly from the controller. The 24V must be
derived from a suitable detector supply kit, which is normally provided as part of a
standard controller installation.
Cards may be linked together to increase the number of magnetometers which are able
to be supported and this solution is ideal for small sites or where WiMag is to be retrofitted
into controllers in place of existing loop detectors.
