4. Play first message by momentarily shorting IN1 on the DCMB (Mother Board). (See Figure 3-
11 on Page 3-12 for location)
Control Module (DCDC): Right (RED) LEDs D4 and D5 “ON”. Relay on DCDC clicks at 1
click per second. When message ends, right LEDs on D4 and D5 “OFF”, relay stops
clicking. (See Figure 3-18)
Amplifier Modules: All LEDs “OFF”.
5. Key Microphone in panel.
Control Module (DCDC): Right (RED) LEDs D4 and D5 “ON”. Relay on DCDC clicks at 1
click per second. When microphone button is released, right LEDs D4 and D5 “OFF”, relay
continues to click. (See Figure 3-18 on Page 3-18)
Amplifier Modules: All LEDs “OFF”.
Press RESET button on DCDC Relay will stop clicking. (See Figure 3-18).
6. Press MAIN (Auto/Manual) Switch to the DOWN position.
Control Module (DCDC): Right (RED) LEDs D4 and D5 “ON”. Relay on DCDC clicks at 1
click per second. Return MAIN Switch to the UP position, right LEDs D4 and D5 “OFF”,
relay continues to click. (See Figure 3-18 on Page 3-18)
Amplifier Modules: All LEDs “OFF”.
Press RESET button on DCDC Relay will stop clicking. (See Figure 3-18 on Page 3-18).

If a malfunction, or system trouble occurs during testing, STOP TESTING.
Correct the problem before you resume testing.
Connect the AC power source before connecting the battery backup power.
Disconnect the battery backup power before disconnecting the AC power
source.
1. Set Configuration Switches to desired settings for supervision tone. See Figure 3-20 for switch
location on the Control Module (DCDC). See Tables 3-2 and 3-3 on Page 3-21 for switch
descriptions.
NOTE:
The tone selected is used to supervise the amplifiers in STANDBY condition. It is also the tone
when the “AUTOMATIC/MANUAL” switch is placed in the “MANUAL” position. The tone will
also play in ALARM if the MDX-2 Module is removed and the Shunt PCB (Figure 3-19 on Page
3-20) is put in its place.
