Installation manual

SAFEPATH Manual Sheet 44 of 78
Rev. C April 1999
Field Wiring Checkout
Refer to NFPA for guidelines on testing signaling system wiring.
CAUTION:
Do not connect input voltage to any equipment until the field wiring has been inspected and approved.
Verify that the field wiring is in full agreement with this manual and with the detailed wiring layout prepared for this installation.
Ensure that no unwanted voltages are present on circuit conductors and ground. Test all ungrounded connectors for electrical
isolation from ground. Test all wires that are not intentionally connected for electrical isolation from each other. Measure and record
the resistance of each circuit pair (this can be done by temporarily short circuiting one end of the circuit).
System Checkout
Refer to NFPA for guidelines on testing signaling systems.
When rated input voltage is applied to the SAFEPATH panel, the unit initializes its program and broadcasts a tone signal through
each output channel for several seconds. The green system normal LED indicator should be on to indicate normal operation. If the
amber system trouble LED is on, a trouble condition is indicated. Refer to the "Troubleshooting and Servicing" section to diagnose
and correct the trouble condition.
The system checkout should include:
1. Testing all inputs and outputs.
2. Testing all connections to equipment that is interconnected with the SAFEPATH panel.
3. Testing all message files for proper audibility, intelligibility, content, and priority.
If a malfunction is discovered during testing, the problem should be corrected immediately before continuing with testing.
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.
