PRE-INSTALLATION
P7 enables or disables an audible device similar to the CSB. This audible sounds
whenever a switch is pressed on either the LVM, SCM-8 or the FCM-6. If this is not
desired the audible can be silenced by changing the jumper installed on P7 to
positions 2 and 3. P7 is configured in the factory (positions 1 and 2) to have the
audible active.
S1 is used to terminate the HNET/XNET. If the RNI is installed at the end of an HNET
network, S1 must be set to the ON position. If the RNI is in the middle of the HNET/
XNET, set S1 to the OFF position.
P5 must be set to the HNET (H) position to select HNET or the XNET (X) position to
select XNET. Only one network, either HNET or XNET, can be used.
INSTALLATION
Remove all system power before installation, first battery then AC. (To power up,
connect the AC first, then the battery.)
