Batteries can emit fumes that are poison-
ous to people, potentially explosive, and
corrosive to electronic components. Lo-
cate batteries so that any fumes are ade-
quately vented per local fire codes.
2) Place the POWER switch (on the front of the
main power supply) in the OFF position and
remove the AC power cable from the outlet.
3) Connect the battery pack leads (customer-
supplied) to TB2 BAT on the NPSA-M or LPSA
(Figure 4-68). Observe the correct polarity.

9.30 Paging Equipment
9.31 By combining a single customer-supplied
paging amplifier with the system' s paging interface
and speaker zone switching, it is possible to pro-
vide a paging system of up to five zones with All
Zone Page capability.
9.32 Figures 4-69, 4-70 and 4-71 show possible
paging arrangements. As a standard feature (part
of the NPRU PCB), the system provides a 600-ohm
output to a paging amplifier. If more than one
paging zone is required, the output of the amplifier
can be routed back to the NPRU PCB where it will
be switched to one of five sets of speakers. The
speaker operated is determined by the access
code dialed by the station user. The actual access
code is assigned in software (see Section 200-255-
300, Programming).
9.33 An All Page code can also be defined in
software. When that code is dialed, all relays will be
activated simultaneously to permit paging to all
speaker zones.
9.34 If the power loads of the different zones are
such that a single amplifier is not suitable, multiple
amplifiers (up to one for each zone) can be con-
nected as shown in Figure 4-71.
9.35 If music is to be broadcast over the paging
system, two arrangements are possible:
1) If the music is supplied from a separate ampli-
fier (as in Figures 4-70 and 4-71), it can be
connected between the speaker common line
and the PG GND input to the NPRU
(PERCEPTlONe J2/J502 and pin 2 or
PERCEPTlONe, Jl/J2 and pin 2). The music
will be connected to all speaker zones when
no page is in progress. When a page access
code is dialed, the music is disconnected from
the zone and the page amplifier output is
connected.
2) If the music is connected to a second input Of
the paging amplifier (Figure 4-69), the PG1
