4.6.2 Checkout Procedure
Connect AC power, then connect batteries.
NOTE: When the AC power source is applied to the panel, the battery voltage check circuitry is
activated. If batteries are not connected within 20 seconds, the panel trouble circuit activates. The
battery voltage check circuitry re-checks for batteries every two minutes. If the batteries are
installed during the two-minute period, the panel remains in trouble until the next re-check.
D11 AC LED (Green) should be “ON” to indicate normal operation.
If D73 TROUBLE LED (Yellow) is “ON,” a trouble condition is indicated. STOP TESTING.
Refer to Chapter 8 of this manual, then troubleshoot and correct the problem before you resume
testing. See Figures 8-1 and 8-2 for location of LEDs.
Perform the following tests:
4.6.2.A Strobe Circuit Test (SPB-80/4 Only)
1. Switch SW2 to the CC position (depressed to the bottom).
2. Short the STB IN terminals. The Strobe Output Circuit should flash. Red LEDs D70
STB1 OUT and D57 STB2 OUT are lighted. Remove the short.
4.6.2.B Audio Output Test
Play a digital message or use the built-in microphone on the SP40S voice evacuation panel and
test the audio output circuit(s).
WARNING: Perform mandatory testing of all protective
signaling systems as required. Test all protective signaling system
equipment using 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 serious
personal injury or death to you and/or others during an emergency
situation.
4.7 Ground Fault Detection
Ground fault detection sensitivity is 600K Ohms for Class B, Style Y connections.
NOTE: The Ground Fault LED D34 may flicker while STB-IN is operated in Cooper Wheelock
Pass-Through Mode (JP5 removed). This DOES NOT indicate the presence of an actual Ground
Fault Trouble.
