LED D13 (AUDIO) “OFF”
LED D10 (PWR) “OFF”
LED D3 (AMP) “OFF”
4. Play each messages by momentarily shorting IN1 through IN8 in turn on Digital Voice Module.
See Figure 3-11 on Page 3-11.
Relay on SCMB clicks at 1 click per second during the playing of each message.
Message will broadcast on all appliance circuits. If Strobe NAC circuits are in use, Strobes will
also flash.
5. Key Microphone in panel.
Relay closure can be heard.
Message will broadcast on all appliance circuits. If Strobe NAC circuits are in use, Strobes will
also flash.
6. If Remote Microphone Station (RMS-2) or the AIM-3 is included, enable it by switching SW5-4
(RM ENABLE) to “ON” on the Single Circuit Motherboard (SCMB).
7. Test the Remote Microphone Station.
8. System is fully operational.
Additional system checkout should include:
Testing all Alarm and Trouble circuits.
Testing all connections to equipment that is interconnected with the SAFEPATH
®
Panel.
WARNING: ALL PROTECTIVE SIGNALING SYSTEMS REQUIRE PERIODIC TESTING. ALL
PROTECTIVE SIGNALING SYSTEM EQUIPMENT SHALL BE TESTED BY
QUALIFIED PERSONNEL AT LEAST TWICE A YEAR FOR PROPER
OPERATION, OR MORE OFTEN IF REQUIRED BY CODES, REGULATIONS
AND LAWS. FAILURE TO MAINTAIN AND TEST PROTECTIVE SIGNALING
SYSTEM EQUIPMENT CAN RESULT IN NOT DETECTING EQUIPMENT
FAILURE THAT CAN CAUSE PROPERTY DAMAGE AND SERIOUS
PERSONAL INJURY OR DEATH TO YOU AND/OR OTHERS DURING AN
EMERGENCY SITUATION.
Section 3-7 – Ground Fault Detection Sensitivity Adjustment
Ground fault detection sensitivity can be adjusted for a set point between 40K Ohms and 500K Ohms.
Selecting a high resistance set point will increase the circuit sensitivity to ground fault conditions. A
high resistance may cause many false trouble conditions.
Selecting a low resistance will decrease the circuit sensitivity and will greatly reduce susceptibility to
false trouble conditions. The lower resistance allows for lower ground fault resistance before a ground
fault conditions occurs.
Before the sensitivity is adjusted, it is imperative to correct (clear) all trouble conditions.
NOTE: The ground fault detection sensitivity set-point shall be the same value as the FACP.
Adjustment Procedure
1. Place "GRND FLT ENB DIP switch in the ON position (SW4, POS 1). See Figure 3-18 on Page
3-17.
2. Disconnect the wire between earth ground and the earth ground terminal on the Mother Board.
(See Figure 9-2 on Page 9-5 for location.)
