Fire Safety
OPERATION
The Model PS-5N7 from Siemens Building
Technologies, Inc. permits remote mounting
of the MXL annunciator modules MKB-1,
MKB-2,
and RCC-1/-1F. In addition, when the
PS-5N7
is used with a PIM-1, it provides an
interface for a remote printer that can be
supervised or unsupervised. Each PS-5N7
occupies one network node.
INSTALLATION
Mounting
The PS-5N7 can be used in an MME-3, MSE-2,
or an RCC-1/-1F enclosure. Mount the PS-5N7
in the following enclosures as described below
(See the Note at the top of page 2 if using a
PIM-1):
Figure 1
PS-5N7 Wiring Diagram in MME-3 or MSE-2 (Without a PIM-1)
1. MME-3—Install in the upper right-hand
corner (See Figure 1).
2. MSE-2—Install in the upper right-hand
corner (See Figure 1).
3. RCC-1/-1F—Install in the lower right-
hand corner (See Figure 2).
Note: In a special application which is
described on page 7, the PS-5N7
can be used as a source of
power in a remote extender
enclosure used to house extra
VSMs/VLMs/VFMs.

Four male/female standoffs are provided in
each backbox in the correct location for
installing the PS-5N7. Place the PS-5N7
over the existing female standoffs. Fasten it,
using the threaded portion of the standoffs
as screws. Use the cable provided (See
Figures 1 and 2) to connect P1 on the
PS-5N7 to P1 on the ANN-1.
Note: If a PIM-1 is used in the config-
uration, refer to the instructions
below.
Using the PS-5N7 with a PIM-1
To support a remote printer, use a PIM-1
with the PS-5N7.
Note: The PIM-1 and PS-5N7 have the
same mounting holes.
When using a PIM-1 with the PS-5N7 in
an MME-3 or MSE-2 backbox (See Figure 3):
1. Mount the PIM-1 first, as shown.
2. Use the four male/female standoffs
provided with the PS-5N7 as screws.
3. Attach the PIM-1 to the female
standoffs.
4. Connect the cable from P1 of the
ANN-1 board to P1 on the PIM-1.
5. Next, mount the PS-5N7 on the same
standoffs, using the four screws from
the PIM-1 kit.
6. Attach the cable supplied with the
PIM to P2 on the PIM-1.
7. Plug the cable from P2 of the PIM-1
into P1 of the PS-5N7; see Figure 3.

When using a PIM-1 Module with the
PS-5N7 in an RCC-1/-1F Enclosure (See
Figures 4 and 5):
1. Mount the PS-5N7 to the right of the
PIM-1 in the bottom of the enclosure.
2. Refer to the RCC-1/-1F Installation
Instructions, P/N 315-095364, for
instructions on the cabling connections.
For additional information refer to
the PIM-1 Instructions, P/N 315-091462.
Power Connection
The PS-5N7 requires a DC input of 14-31 VDC.
This input is available from the MMB or the
PSR-1. Refer to Figure 5 for the correct
wiring instructions.
Using the PS-5N7 with Style 4
(2-Wire) Network Connections
Use screw terminals 1 and 2 for Network A.
DO NOT USE wire terminals 3 and 4 in this
configuration. See Figure 5 for additional
wiring information. Refer to the PSR-1 Instal-
lation Instructions (P/N 315-090911) for more
details on Style 4 networks.
Using PS-5N7 with Style 7
(4- Wire) Network Connections
Do not place the PS-5N7 module in the last
position on a Style 7 Network. Use a NET-7
at each end of the network to provide proper
supervision.
Use screw terminals 1 and 2 for Network A,
terminals 3 and 4 for Network B. Refer to
Figure 5 for wiring instructions.
Wiring Restrictions
Network
The MXL supports a maximum of 64 network
nodes. Each module in the list below repre-
sents one node. Do not plan a system with
more than 64 of these modules.*
MMB (one allowed per system)
MOI-1 MOI-7
NET-4 NET-7
NET-7M PS-5N7
The total wire resistance in both wires of the
network pair cannot be more than 80 ohms.
*If the system has more than 32 nodes, an
REP-1 module must be used.

4
Notes:
1. Use a minimum wire gauge of 18 AWG.
2. Use a maximum of 80 ohms per pair of
wires for the network connections.
3. Use twisted pair or shielded twisted pair for
network connections.
4. Terminate the shield ONLY at the MMB
enclosure.
5. Eliminate all Network B wiring for Style 4.

ELECTRICAL RATINGS*
24 VDC Power
You may connect multiple PS-5N7s to the
same 24V power supply as long as the total
line loss is within specified limits. Follow the
information given below to calculate the
allowable line losses.
CAUTION
Failure to follow these guidelines
may result in excessive voltage
drops that cause improper or no
operation of the system.
To determine the total line loss, and there-
fore, the maximum cable length permitted,
use the following values and limits.
Vmax—The maximum allowable voltage
loss due to wire resistance. Vmax must
not be more than 4V. (See Table 2.)
Imax—The total alarm current drawn by
all PS-5N7 modules connected to the 24
VDC supply. If a PIM-1 is used in the
system, include its current. (See the Imax
values for the approved power supplies
at the bottom of this column. See Table
1 also.)
Rmax—The value of wire resistance
that results in a 4 volt drop due to Imax.
To calculate the total line loss, use the fol-
lowing equation:
Rmax = Vmax ÷Imax
(Where Vmax = 4V in all cases)
The Rmax result obtained with this equation
is the total of all wire resistance in ohms in
the 24 VDC supply lines.
The following power supplies are compat-
ible with the PS-5N7. They are listed with
their maximum output current (Imax):
MMB 1 amp
PSR-1 2 amps
PLM-35 1.5 amps
ALARMSAF 4 amps
PAD-3 3 amps
The maximum module current is shown in
Table 1 below.

allowable cable length. (See Figure 5.)

Using the PS-5N7 to Drive an OMM-1
In order to add Voice hardware to a remote
enclosure, use a PS-5N7 module to drive an
OMM-1 if the following conditions apply:
1. The remote enclosure is not
connected to the MMB, and
2. There are multiple MXLs that are not
networked.
Adding a PS-5N7 and an OMM-1 under
these conditions provides power as well as
communication with the MXLV. Refer to
Figure 6 for the correct wiring information
for this configuration.
