Model SS4-AI Detector Faults
Detector Faults
The Model SS4-AI Detector will issue a Fault (or Trouble) condition by de-
energizing its Fault Relay (J5 connector). The following are Model SS4-AI
Detector Faults:
a. Temperature Fault. The Detector will Fault if the internal
temperature during operation is above 85°C or falls below -40°C.
Requires factory re-certification to correct. (both LED's blink
rapidly)
b. Excessive Input Voltage Fault: The Detector will Fault if the
voltage supplied to it is too high. Requires factory re-certification to
correct. (both LED's blink rapidly)
c. Low Input Voltage Fault: The Detector will Fault if the voltage
supplied to it is to low. Check the voltage at the power connector J1
or J2 Pins 1 and 4. If the voltage is above 15 volts factory service
may be required. (One LED is on until fault is corrected.) If the
voltage is below 15 volts check the wiring and power supply.
d. No Power Fault: The Detector will Fault if the voltage supplied to it
is interrupted or turned off. (No LED indication.) Check voltage at
the power connector J1 or J2 Pins 1 and 4. If no or very low
voltage is measured check wiring and power supply.
e. Detector Fault: The Detector will Fault if any one of its Detectors
fails the automatic built in test. (One LED is on until the fault is
corrected.) Begin by thoroughly cleaning the Lens both inside and
outside, also clean the exposed surface of the Detector elements
and the protective grill mounted on the outside of the housing
cover. Reassemble and apply power. Wait for 10 to 15 minutes if
the fault recurs factory service may be necessary.
f.
Relay Fault: The Detector will Fault if one of its Relay circuit fails.
(One LED is on until the fault is corrected.) Return to factory for
service.
g. Self-Checking Fault: The Detector will Fault if its internal
microcomputer self-checking circuitry and software finds a failure.
(One LED is on until the fault is corrected.) This class of fault may
be caused by several things. Check for proper grounding of the
device and for noise on the power wires. If fault persists return
detector to factory for service.
