S4000C
6.1.5 F6 Low Supply Voltage
This fault occurs if the supply voltage at the S4000C drops below +18.5VDC.
ACTION - Ensure that the supply voltage is at least +20VDC at the Model S4000C.
NOTE:
With long supply leads, a considerable voltage drop may occur, due to the electrical
resistance of the leads. The maximum cable resistance, which the Model S4000C can
tolerate, is dependent on the supply voltage: a maximum of 20 ohms per conductor (40
ohms loop), at +24VDC minimum, or a maximum of 10 ohms per conductor (20 ohms
loop), at +20VDC minimum.
6.1.6 F7 EEPROM Verification Failure
This fault occurs when an attempt to verify the setup/calibration parameters just written to the
EEPROM memory fails.
ACTION - The unit must be returned to the factory or authorized service center for repair.
6.1.7 F8 Failure to Complete Setup
This fault occurs if the unit is left in setup mode for more than 6 minutes.
ACTION - Exit setup mode. Enter setup mode again if it is necessary to change any user
selectable options.
6.1.8 F9 Gas Check Period Exceeded
If the Model S4000C is left in the gas check mode for more than six minutes without a Test Gas
being applied or if test gas is left on the gas check mode for more than 6 minutes, this fault will
occur.
ACTION - Place the magnet over the GM Logo on the cover to return the unit to normal
operation.
NOTE:
Anytime a sensor is replaced, the unit should be disconnected from all alarms, as the
unit may go upscale upon power-up.
6.1.9 F10 Switch Error
This fault occurs if the remote reset, remote calibrate, or the magnetic switch are closed for
more than two minutes.
ACTION – Check the wiring on the remote reset and remote calibrate switches. Once the short
circuit is cleared, the unit will return to normal operation. If the magnetic switch is shorted, the
unit must be returned to the factory or authorized service center for service.
