Use this product according to this instruction manual. Please keep this instruction manual for future reference.
MODEL NUMBER:
109920 SP4-APS
1.0 GENERAL:
The Addressable Paging Splitter module (SP4-APS) is designed to be used with Wheelock’s SP40/2 SAFEPATH4 panel and
the SP4-TZC Zone Controller. The SP4-APS can also be mounted in SAFEPATH4 Audio Booster (SPB-160, SPB-80/4, and
SPB-320) panels. The SP4-APS provides a means for expanding one supervised audio output zone to four Class B or two
Class A supervised zones. The SP4-APS also provides two expansion outputs that can be used to add additional audio
booster modules in Class A or B configuration. The SP4-APS is UL Listed under Standard 864, Control Units for Fire
Protective Signaling Systems. It is for indoor use only.
One SP4-APS can be mounted inside the SP40/2 panel. The use of the Splitter Mounting Bracket (SPMB4Z) is required
when mounting the SP4-APS splitter(s) inside the Audio Booster panels.
The Addressable Paging Splitter module (SP4-APS) is also used to expand and distribute supervised telephone paging and
background music to selected zones when the SAFEPATH4 system is not in the alarm condition. When the SAFEPATH4
system is in the alarm condition all telephone paging and background music inputs are silenced and the emergency message
is broadcast on all zones. The SP4-APS is used with the Telephone Zone Controller (SP4-TZC) and controls the distribution
of the telephone paging and background music functions.
NOTE: Use of the Telephone Zone Controller (SP4-TZC) is supplementary.
The SP4-APS contains 16 LED indicators used to monitor and troubleshoot the module.
Refer to the Installation Instructions for the Telephone Zone Controller (SP4-TZC) P84567 when connecting the SP4-APS

Terminals for the RS-485 connections are used with the SP4-TZC and are explained in the SP4-TZC installation instructions.
3.1 Audio Zone Output Wiring
The SP4-APS can be configured for either “CLASS A” or “CLASS B”. It cannot do both at the same time. The maximum
audio power output on any zone is 40 watts. Expansion (EX1, EX2) terminals follow the Class A or B setting that applies to
all zones.
Instead of speakers, up to four SPB-160 or SPB-80/4 (or two SPB-320) Audio Boosters may be connected to an audio output
zone, provided that nothing else is on that zone. The total number of Audio Boosters combined shall not exceed 33.
NOTE: Factory setting is for Class B Wiring.
3.1.1 “CLASS A” Audio Wiring:
When an installation requires “CLASS A” audio field wiring on the SP4-APS module, the Class Selector Switch (SW2)
must be set for “CLASS A”. Note that no end-of-line resistors (UL Listed 10K Ohm, EOLR) are used on any of
the SP4-APS module audio output zones as shown in Figure 3. Zones Z1 and Z2 are connected in Class A
configuration as well as Z3 and Z4. Figure 3 shows the SP4-APS with SW2 and the audio field wiring set for “CLASS
A”.
The audio zone outputs are either 25Vrms or 70.7Vrms matching the audio input voltage. Remember, the SP40/2 has a
maximum audio output to the splitter of 40 watts, while the Audio Boosters have a maximum audio output to the splitter
of 80 watts.

3.1.2 “CLASS B” Audio Wiring:
When an installation requires “CLASS B” audio field wiring, the Addressable Paging Splitter module’s Class Selector
Switch (SW2) must be set for “CLASS B.” Note that end-of-line resistors (UL Listed 10K Ohm, EOLR) are
required at the end of each audio output zone even if no speakers are present on a zone. End-of-line resistors are
required on the EX1 and EX2 connections whether they are used or not. Figure 4 shows the SP4-APS set for CLASS B
audio field wiring:
The audio zone outputs are either 25Vrms or 70.7Vrms matching the audio input voltage. Remember, the SP40/2 has a
maximum audio output to the splitter of 40 watts, while the Audio Boosters have a maximum audio output to the SP4APS of 80 watts.

3.2 Other Wiring
3.2.1 Expansion Circuit Wiring
The Expansion Circuits (EX1, EX2) are used to link additional audio booster panels (SPB-160, SPB-80/4, and SPB-320)
through the SP4-APS. The audio zone outputs are either 25Vrms or 70.7Vrms matching the audio input voltage. EX1
and EX2 are current limited outputs. If an over current condition is detected, the affected Expansion Zone(s) will
disable their audio output. When the over current condition has been cleared and the affected Expansion Zone(s) go
back to “Normal” condition, the audio output will be re-enabled. To ensure that current limiting works properly, for
25Vrms JP1 must be open, for 70Vrms JP1 must be closed. SPB-160 and SPB-80/4 enclosures contain one audio
booster module, while the SPB-320 contains two. The SP40/2 has a maximum audio output to the splitter of 40 watts,
while the Audio Boosters have a maximum audio output to the splitter of 80 watts. Each audio booster module
connected to the expansion circuits uses 1.2 watts. There is a limit of 33 Audio Boosters that can be connected to an
SP40/2 using SPB-160 or SPB-80/4 models. Each SPB-320 counts as two SPB-160 models.
The wiring of EX1 and EX2 for “CLASS A” or “CLASS B” is determined by the wiring of the zone outputs and switch
SW2 setting. If SW2 is set for “CLASS A”, then all zone outputs and expansion outputs must be wired for “CLASS A”.
When using the SP4-APS in “CLASS B” configuration, end-of-line resistors (UL Listed 10K Ohm, EOLR) must be
used at the end of each expansion circuit.
3.2.2 24VDC Wiring

The SP4-APS requires 24VDC input in order to operate. Wire the 24VDC from +/- 24VDC connections on the SP40/2
or the DC OUT connections on the applicable audio booster to the +/- 24VDC IN connections on the splitter. If two
SP4-APS are used on an SPB-160 or two are used with each SPB-160 in the SPB-320 audio booster enclosure, wire the
24VDC OUT connections on the first SP4-APS to the +/- 24VDC IN connection on the second splitter. Observe correct
polarity. See Figure 5 for connection locations.

The SP4-APS AUDIO IN uses the Audio Out from the SP40/2 or an audio booster, which is either 25Vrms or
70.7Vrms. The total audio output from all zones on the SP4-APS must not exceed its audio input power. See Table 2.
See Figure 2 for the location of the AUDIO IN. The SP4-APS uses 8 watts of audio power to operate (1.35 watts per
zone.)

6.1 MODES OF OPERATION:
6.1.1
STANDBY MODE:
Standby mode occurs when the Addressable Paging Splitter is not in ALARM and is not selected for BGM or a
Telephone Page. Standby mode is indicated when only the GREEN power LED indicator is ON.
6.1.2
BACKGROUND MUSIC MODE:
Background Music Mode occurs when the SP4-TZC sends BGM commands to Addressable Paging Splitter
Modules (s) via RS-485 digital control signals. By default, The SP4-TZC selects all available zones on all SP4APS for BGM so that each SP4-APS enables its four available audio output zones. Zone specific BGM selection
can be accomplished through the SP4-TZC module using the SP4 Telzone Programmer software. See the SP4-TZC
installation sheet (P84567) for further information.
6.1.3
TELEPHONE PAGING MODE:
Paging Mode occurs when telephone-paging commands are sent from the SP4-TZC to the SP4-APS Splitter(s) via
RS-485 digital control signals (See Figure 13 for location). See the SP4-TZC installation sheet (P84567) for further
information on the RS485 connections. When the addressed SP4-APS receives the paging command, it enables the
selected zones audio output relays to allow audio to pass. The SP4-TZC will send commands to all networked SP4APS modules not selected for paging to turn off their audio output zones.
6.1.4
ALARM MODE:
Alarm Mode occurs when an alarm signal initiates the SP40/2 into an alarm condition, or when the SP4-APS
ALARM input or output wiring is in trouble. When the SP4-APS module is in ALARM, it turns on all audio output
zones and ignores any SP4-TZC paging and/or BGM commands. When the SP4-APS is installed with an SP-40/2
it must be set for “CC MODE” (Contact Closure). When the SP4-APS is installed with an Audio Booster product it
must be set for “NAC MODE.” The SP4-APS uses 3.0mA at 24VDC in the NAC mode. See Figure 14 for the
location of the ALARM terminals.
P84577 G
Sheet 11 of 14
7.0 TROUBLESHOOTING PROCEDURES:
The SP4-APS supervises all output zones and the module itself for trouble conditions. If a trouble condition is detected the
yellow GENERAL TROUBLE LED indicator is “ON”.
•
If the SP4-APS is connected to the SP40/2, the TROUBLE and the AUDIO SHORT LED indicators on the SP40/2 will
also be “ON”.
•
If the SP4-APS is connected to an Audio Booster (SPB-160, SPB-80/4, SPB-320), the TROUBLE and the AUDIO
SHORT LED indicators on the Audio Booster will also be “ON”.

SP4-APS Power and Trouble LED Indicators
Figure 15 shows the Power and Trouble LED indicators on the SP4-APS PC board.
1.
Ensure that the green POWER LED is “ON”. If no LED's are lighted, check the 24VDC input power.
2.
Verify that SW1 (NAC/CC) switch is set to the desired position.
3.
Verify the SW2 (CLASS A or B) is set to the correct zone circuit configuration.
4.
Verify wiring is correct.
5.
If the yellow TROUBLE LED is “ON” an output circuit supervision trouble or module trouble is indicated. Remove the
SP4-APS cover and observe the 12 yellow AUDIO TROUBLE LED's as shown in Figure 14 to determine the reason
for the trouble using Table 3. (NETWORK TROUBLE LEDS are used when the SP4-APS is used with the Telephone
Zone Controller (SP4-TZC)).
6.
For each SHORT LED “ON”, check the speaker output wiring for that zone for a short or a faulty speaker appliance.
7.
For each OPEN LED “ON”, check the speaker wire run for that zone for an open or that the end of line resistor (if
applicable) is missing.
