Door Open Alarm
A door open alarm can be configured and installed in the WRH. This is arranged with a door
switch connected to P28, as illustrated in Figure 3-8.
Fiber Link Interface (FLI)
The FLI feature makes it possible to interconnect WRHs. By using an RF distribution fiber
network, no wire or other communication device is required.
Wire Link Interface (WLI) Network (IP to R2R)
Two types of WLI networks are available for the WRH: Internet Protocol (IP) and a Repeater-
to-Repeater Link (R2R).
The network cables are connected to the P34 or P36 WLI ports on the DIA PCBA as
illustrated in Figure 3-9. The cables can either be interconnected at the P1 terminal on the
connector PCBA located to the right in the cabinet or to both P34 and P36.
Any cable type can be used for indoor installations. For outdoor installations, the Li 2YC11Y,
2x2xAWG24/222, non-halogen, Metrofunkkabel-Union cable type is recommended. Use
strain relief bushings or connectors at the bottom of the WRH. If the link cable between two
WRHs is longer than 25 meters, an RS-485 WRH is required as illustrated Figure 3-10.
