FIBER CONNECTION
The fiber optic connection is made via a ST connector located on the back of the unit. Be sure to allow
sufficient room for the required minimum bend radius of the fiber cable used.
AIPHONE INPUT / OUTPUT CONNECTIONS
AiPhone input / output connections are made via a terminal block on the back of the unit. See the drawing
above for the three copper wire connections to the AiPhone LEF Master. Please note that if the ‘E’ and ‘-‘
connections are shorted at the master only one copper wire need to be run between the RR-89A-L and the
master for those two signals along with a jumper across the ‘E’ and ‘-‘ terminals on the RR-89A-L.
CONTACT INPUT CONNECTIONS
Contact closure input connections are made via a terminal block on the back of the unit. See the drawing
above for the location of the two contact input wire connections.
