Descriptions and Locations
Refer to Figure 4-1.
1.
TONE VOLUME
- Controls the level of all tones produced by the PCM system.
2. BGM SRC VOLUME - Sets background music level for one mode of operation. Used only when an amplifier without
a music input is used as the paging amplifier (see Section 7).
3. POWER - Indicates that power has been supplied to the module. One exists on each module.
4. OVERRIDE - Secondary paging input with higher priority than TEL LINE input. Connects to either loop start trunk or
dry audio signal with contact closure (see Section 5.7).
5.
PAGE PORT/TRUNK
- Interface to telephone switch (see Section 5).
6.
TEL INT SEL Switches
- Sets telephone interface type for the LOOP START/GROUND START, TRUNK/PAGE
PORT and STATION jacks on the PCMTIM module (see Section 5).
7. 90V NIGHT RING/STATION - This RJ11 jack provides connections to the internal Night Ringer for both 90V analog
ring and the Station type interface.
8. PCMTIM Terminal Strip - Provides connections for Night Ring contact closure activation, background music source
(one mode of operation only) (see Section 7), ground start interface ground (see Section 5.3), and two sets of contact
closures that change state whenever a paging zone is active (see Section 11.11).
9. PCMCPU Terminal Strip - Provides connections to background music audio signals (see Section 7), system expansion
signals (see LUPCMADD manual), EM/SC signal trigger (see Section 9.1), clock resynchronization (see Section 9.2),
and auxiliary power supply input.
10.
PCMTBM Terminal Strip
- Provides connection to main paging amplifier (see Section 6).
11.
PCMZPM Terminal Strip
- Provides connections to paging speakers (see Section 8), separate local background music
source (see Section 7), and relay driver outputs (see Section 9.3).
12. OUTPUT Switch - Switch setting determines if the PCMZPM module will be compatible with 70V (Hi) speaker systems
or self-amplified speakers (Lo). Locking plate guards against accidental changes in setting.
13. BGM Jumper Field - Jumpers control whether background music is inhibited to a specific zone or all zones
(see Section 7).
14. LPBGM VOLUME - Controls the level of background music in zones using self-amplified speakers. Works only with
system-wide BGM, no effect if local BGM source is used.
15.
TALK BACK Switch Bank
- Determines if a 70V speaker zone will operate as a two-way hands-free talk back zone or
as a one-way paging zone (see Section 8.3).
16.
TALK BACK DELAY
- Controls the amount of delay, after speaking stops, before the system switches to the listen
mode during talk back operation (see Section 8.3).
