CIRCUITRY ON THE SAFEPATH PANEL UNLESS THE CIRCUITRY HAS DISCHARGED FOR ONE HOUR
AND A SAFE DISCHARGE PROCEDURE IS USED.
WARNING: PROVIDE UL REQUIRED ALTERNATIVE SIGNALING MEANS DURING TROUBLE CONDITIONS AND
SERVICING TO ASSURE ADEQUATE PROTECTION OF PEOPLE AND PROPERTY. HAVE QUALIFIED
SERVICE PERSONS IMMEDIATELY REPLACE ANY MODULES THAT HAVE MALFUNCTIONED.

water, steam, cleaning liquids or sprays on the SAFEPATH.
CAUTION:
User servicing of the SAFEPATH is limited to the following:
- Field wiring changes following the instructions in the "Installation" section of this manual.
- Reprogramming voice messages following the instructions in the “Message Recording” section of this manual
(DX-200 configured panels only).

AFTER ANY TROUBLESHOOTING PROCEDURE IS COMPLETED, PERFORM A COMPLETE SYSTEM CHECKOUT.
The SAFEPATH panel monitors system integrity. Items monitored for integrity are:
1. Strobe circuit field wiring.
2. Speaker circuit field wiring.
3. Amplified speaker audio circuit field wiring.
4. Amplified speaker power circuit field wiring.
5. AC input voltage.
6. Battery voltage level.
7. Battery circuit field wiring.
8. Amplifier functionality.
9. DX-100 and DX-200 functionality.
10. Internal wiring.
11. Internal fuses.
12. Remote microphone functionality and wiring.
System status is indicated to the operator via the NORMAL and TROUBLE indicators. If a trouble condition is detected, the
SAFEPATH panel will respond as follows:
1. Turn off the NORMAL indicator.
2. Turn on the TROUBLE indicator.
3. Transfer the Form C trouble contact to the trouble position.
4. Turn on the internal trouble sounder.
5. Turn on the external trouble audible.
6. Turn on a trouble location indicator, if appropriate.
If the acknowledge push-button is pressed, the internal trouble sounder and the external trouble audible will be silenced. All other
trouble indicators will still indicate a trouble condition. The internal trouble sounder and the external trouble audible will not resound
for subsequent trouble conditions, until all trouble conditions have cleared. If the main power fuse on the controller board is blown,
the internal trouble sounder and the external trouble audible will not sound. All other trouble indications occur normally. When there
are no trouble conditions detected, the NORMAL indicator will always be on and the TROUBLE indicator will always be off. When a
trouble condition is detected, the NORMAL indicator will always be off and the TROUBLE indicator will always be on.
