Chapter 1 - Safety Precautions Section 1-1 - Read This Manual Personnel properly qualified in the application and use of life safety equipment ("qualified personnel") shall read this manual carefully before performing any actions to specify, apply, install, maintain and operationally test SAFEPATH® Panel products in accordance with the instructions in this manual. This manual shall be kept with the SAFEPATH® Panel for reference during the life of the system.
Notification equipment cannot last forever. Even though SAFEPATH® Panel is expected to last up to ten years, any of its parts or components could fail before then. Therefore testing of the entire protective signaling system, including the SAFEPATH® Panel, all notification equipment, as well as all messages and their output channel, and priority assignment, shall be conducted at least twice each year, or more often as required by local, state and federal codes, regulations and laws, by qualified personnel.
Section 1-5 - Audio Output Considerations WARNING: AUDIBLE SIGNALS MAY MASK MEDICAL EQUIPMENT MONITORING ALARMS. WHERE MEDICAL EQUIPMENT MONITORING ALARMS ARE IN USE, DO NOT USE AUDIBLE SIGNALS; PROVIDE VISUAL NOTIFICATION APPLIANCES IN HIGHLY VISIBLE LOCATIONS. CAUTION: The output of the audio system may not be heard in all cases.

Procedure 1. See Figure 3-17 on Page 3-15 for SAFEPATH® Panel mounting hole layout. 2. Remove Amplifier Module from the enclosure. 3. Mark and drill mounting holes for appropriate screws and anchors to ensure secure mounting to the type of surface at the selected location. 4. Prevent dust and dirt contamination of the SAFEPATH® Panel during installation. This contamination can interfere with the operation and reduce the expected life of the equipment. 5.
Section 3-6 System Checkout Refer to NFPA 72 (1999 Edition) for guidelines on testing notification systems. CAUTION: If a malfunction, or system trouble occurs during testing, STOP TESTING. Correct the problem before you resume testing. Insure that speaker and strobe NAC Circuits are not connected to the SAFEPATH® Panel, and that 10K Ohm ¼W EOLR test resistors are connected in their place on the Mother Board. 1.
Final Checkout CAUTION: If a malfunction, or system trouble occurs during testing, STOP TESTING. Correct the problem before you resume testing. CAUTION: Connect the AC power source before connecting the battery backup power. Disconnect the battery backup power before disconnecting the AC power source. 1.

(See Figure 9-2 on Page 9-5 for location) The potentiometer is a 12-turn device, there will be need to rotate the shaft repeatedly. The potentiometer produces a clicking sound when rotated beyond its end point. 4. On the Mother Board (SCMB), place a resistor with the desired set-point value (40K Ohm to 500K Ohm, +/- 5% Tolerance) between the +24VDC terminal on TB4 and the earth ground terminal.
Calculating Backup Battery Requirements A battery calculation worksheet is available at the back of this manual for assisting in calculating battery backup. It is necessary to calculate the current draw for battery backup requirements, The current requirements depend on the system configuration and the optional modules installed. Battery Backup current has two separate calculations that are added together. They are Standby Current and Alarm Current.

WARNING: BEFORE PERFORMING ANY OF THE FOLLOWING TROUBLESHOOTING PROCEDURES, THE PRELIMINARY TROUBLESHOOTING INFORMATION AT THE BEGINNING OF THIS “TROUBLESHOOTING” SECTION ON PAGE 7-1, MUST BE READ, UNDERSTOOD, AND FOLLOWED. Procedure A If the green NORMAL LED is “OFF”, the yellow TROUBLE LED is “OFF”, and no module LEDs are “ON”, then a power loss condition has occurred. A power loss condition may be caused by: 1. 2. 3. 4. Loss of AC input voltage and/or battery back-up voltage.
Perform the following: 1. 2. 3. 4. 5. Check EOLR and verify that it is a UL LISTED, 10K Ohm, 5% Tolerance, 1W Resistor. Check that the EOLR is properly in place. Verify that the Visual Notification Output field wiring is intact. Verify that all fuses on the SAA/SALL module are functioning. If trouble does not clear, remove strobe appliance circuit wiring from Motherboard and place a 10K Ohm 1/4W minimum resistor on strobe output (Figure 3-1 on Page 3-2).
Procedure F On the Single Circuit Mother Board (SCMB), the green NORMAL LED is “OFF”, the yellow TROUBLE LED is “ON”, and the AMP LED on the SAA/SALL module is “ON”, then an amplifier trouble condition has occurred. An amplifier trouble condition may be caused by: 1. A faulty SAA/SALL module. 2. A faulty Motherboard (SCMB). Perform the following: 1. Replace the SAA/SALL module. 2. Replace the Motherboard (SCMB).
Procedure I On the Single Circuit Mother Board (SCMB), the green NORMAL LED is “OFF”, the yellow TROUBLE LED is “ON”, and the MDX-2 SYSTEM NORMAL LED is “OFF”, SYSTEM TROUBLE LED is “ON”, and the TROUBLE LED is “OFF”, then the digital voice module may be completely inoperative. This condition is caused by: 1. 2. 3. 4. Too low input voltage on the digital voice module. Missing or improperly installed program memory EPROM. Broken TROUBLE LED (digital voice module is operative if this is the cause).
3. Missing or improperly installed message memory EPROM's. 4. One or more of the messages were not programmed completely. 5. Failed circuitry on the MDX-2. If the error was due to one of the first four causes, the trouble will clear automatically when the cause is corrected. The first four causes should only occur when power is first turned on to the Series MDX-2. When a message memory error is indicated, perform the following: 1.
5. Remove the malfunctioning module(s) and install the replacement module(s). Perform all checkout procedures described in the “Installation” section of this manual to make sure the replacement module(s) is (is) operating properly. Section 7-3 – Single Circuit SAFEPATH® Module Wiring Diagram Figure 7-4 on Page 7-13 illustrates the Single Circuit SAFEPATH® Module Wiring between modules. Note the wires are color-coded.
