SETTING THE NETWORK
ADDRESS (S1)
(See Figure 2)
The PSR-1 occupies one network address in the
MXL System. You may have up to 31 PSR-1
power supplies in your system. Regardless of
how many PSR-1 power supplies are used, you
MAY NOT exceed 3000 initiating points.
Each PSR-1 must be placed at a unique
address in the system. Use the CSG-M print-
out to determine the address of the PSR-1. Set
the network address on S1 using Table 1.
Note that the PSR-1 network address switch is a
9-position switch. Switch position 9 is not used at
this time. Set it to the OFF or Open position.
When used as a standalone power supply, the
network address does not need to be set.
MOUNTING
Mount the PSR-1 Remote Power Supply on the
MBR-MP mounting plate in the MME-3 enclosure
as shown in Figure 3.
1. Place the PSR-1 over the four standoffs in
the upper left portion of the mounting plate.
2.
Secure it in place using the hardware provided.
MAKING THE NETWORK
CONNECTION (TB4)
For the PSR-1 to communicate with the MXL, a
NET-4 or NET-7 network interface card must be
installed into P7 of the PSR-1. For a NET-4, con-

of TB4 as indicated in Figure 4. Termi
nate the
shield at the MMB only. For a NET-7,
refer to Figure
2 of the NET-7 Installation Instructions (P/N 315-
091914) and connect the network to terminals 1, 2,
3, and 4. For a NET-7 network connected to an
MMB-3, refer to Figure 5. When the PSR-1 is used
as a standalone power supply, neither NET-4 nor
NET-7 is needed. If an MKB-2 is installed, the NET-
7 must be installed in a MOM.
WIRING
Wiring Alarm and Trouble Relays (TB1)
Two relays are provided for local control of alarm
and trouble indication.
These relays are controlled
by
the MXL through CSG-M output logic. The alarm
