INSTALLATION INSTRUCTIONS
3 MESSAGE EXPANDER MODULE (SP4-3MEM)
(FOR SP40/2)
Use this product according to this instruction manual. Please keep this instruction manual for future reference.
MODEL NUMBER:
SP4-3MEM
GENERAL:
The 3 Message Expander Module (SP4-3MEM) is designed to be used with Wheelock’s SP40/2 SAFEPATH4 panel. The SP4- 3MEM provides a
means of expanding the number of digital voice messages by as many as three.
One SP4-3MEM can be connected to the SP40/2 panel. It is connected inside the panel enclosure in the center of the SP40/2 motherboard.
The SP4-3MEM contains its own microprocessor and digital memory chip. It can playback up to three prerecorded digital messages. The digital
voice memory chip memory capacity is divided into three 20-second sections. Each section corresponds to one of the corresponding input circuits. If
the length of a message exceeds the 20 seconds, it will continue playback into the next section. The next section cannot contain a new message. The
exception is the third section, which will stop playback at the end of the 20 seconds. The following table describes the playback feature.
NOTE: All CAUTIONS and WARNINGS are identified by the symbol . All warnings are printed in bold capital letters.
WARNING: PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE USING THIS PRODUCT. FAILURE TO COMPLY
WITH ANY OF THE FOLLOWING INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER
APPLICATION, INSTALLATION AND/OR OPERATION OF THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH
COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

2 Message Selection >20 sec but <40 sec <20 sec
2 Message Selection <20 sec >20 sec but <40 sec
1 Message Selection >40 sec but < 60 sec
< = symbol for less than
> = symbol for greater than
The digital message chip shall be recorded at Wheelock Inc. The SP40/2 does not have the capability to record messages at the panel. When
purchased a 3 Message Expander Module custom message chip shall be recorded and installed by the manufacturer. The digital message chip cannot
be purchased and installed on site.
The NAC input voltage range for initiating the messages is 8 to 33VDC. The operating voltage on the circuit board is 5VDC. The standby current is
35mA, and the maximum alarm current is 45mA.
The three NAC inputs on the SP4-3MEM provide initiation of the message in the corresponding section on the digital voice message chip. These
inputs have a higher priority than the three messages on the SP40/2. The following is a list in the order of priority on the SP40/2 when the SP43MEM is used:
1. SP40/2 On board Microphone
2. Remote Microphone (SPRM) (Optional)
3. SP4-3MEM IN-A1
4. SP4-3MEM IN-A2
5. SP4-3MEM IN-A3
6. SP40/2 IN1
7. SP40/2 IN2
8. SP40/2 IN3

TROUBLESHOOTING PROCEDURES:
Figure 9 shows the location of the power and trouble LED's on the SP4-3MEM PC board.
1. Insure that the green POWER LED D16 is “ON”. If no LED's are lighted, check the SP40/2 to insure it is on. Turn power off
prior to checking the 20 pin terminal and insuring all pins are properly seated.
2. Verify wiring is correct.
3. Verify jumpers are correct.
4. If the yellow DV TROUBLE LED is “ON”, a Digital Voice Memory Chip (U7) failure is indicated. Also the SP40/2 will
indicate a trouble condition.
5. If the yellow AUX TROUBLE LED is “ON”, a Remote Microphone (SPRM) trouble has occurred. Also the SP40/2 will
indicate a trouble condition. Troubleshoot the SPRM and connecting wiring.
6. A failure of the SP4-3MEM will cause a trouble condition to occur on the SP40/2 turning ON the TROUBLE LED. Turn power
off prior to removing the SP4-3MEM and insure the SP40/2 functions correctly. If the SP40/2 operates properly, replace the
SP4-3MEM with a new one.
