MODEL NUMBER:
109900 SP4Z-A/B
GENERAL:
The Class A/B Splitter (SP4Z-A/B) is designed to be used with Wheelock’s SP40/2 SAFEPATH4 panel and the SAFEPATH4 Audio
Booster (SPB-160 and SPB-80/4) panels. The SP4Z-A/B provides a means for expanding one supervised audio output zone to four
Class B or two Class A zones. The SP4Z-A/B is UL Listed under Standard 864, Control Units for Fire Protective Signaling Systems.
They are for indoor use only.
One SP4Z-A/B can be connected to the SP40/2 panel. It is to be mounted inside the panel enclosure onto the backplane in the upper
right hand corner. Two SP4Z-A/B's can be connected to the SPB-160. One SP4Z-A/B can be connected to the SPB-80/4. It is to be
mounted inside the SPB-160 or SPB-80/4 panel on the Splitter Mounting Bracket (SPMB-4Z - purchased separately) mounted over the
24VDC Power Supply (SAPS). The SP4Z-A/B has a maximum power output per zone that cannot exceed what is listed in Table 1.
NOTE: All CAUTIONS and WARNINGS are identified by the symbol

TROUBLESHOOTING PROCEDURES:
Figure 9 Power and trouble LED's on the SP4Z-A/B Splitter PC board.
1.
Insure that the green POWER LED is “ON”. If no LED's are lighted, check the 24VDC input power.
2.
Verify wiring is correct.
3.
Verify jumpers are correct.
4.
If the yellow TROUBLE LED is “ON” an output circuit supervision trouble is indicated. Remove the SP4Z-A/B cover and observe
the 8 yellow LED's as shown in Figure 9 to determine the reason for the trouble.
5.
For each SHORT LED “ON”, check the speaker output wiring for that zone for a short or a faulty speaker appliance.
6.
For each OPEN LED “ON”, check the speaker wire run for that zone for an open or that the end of line resistor is missing. With the
zone wiring removed from the SP4Z-A/B, a resistance reading on the zone will indicate the 10K Ohm EOLR and the wire
resistance if the circuit is correct.
7.
If a zone output does not operate and the green POWER LED is “ON" while the yellow TROUBLE LED is “OFF”, the SP4Z-A/B
splitter has malfunctioned. Replace.
