A malfunction is one of the following:
high power voltage;
low power voltage;
the level of the light background exceeds the maximum allowed;
the level of interference exceeds the maximum allowed;
the signal level is higher than the allowable level;
the signal level is less than the allowable level.
Power and background malfunctions are reset automatically after the causes
have been eliminated, as well as from the remote control or power interruption; the
remaining faults can be cleared either by the remote control or by interrupting the
power.
3.3 Remote control unit PDU-L allows:
- set the test signal “ALARM-TEST” (button “3”)
- set the test signal "FAULT-TEST" (button “2”);
- cause the receiver to its initial state (reset) when a fault and/or the state of
the test fire (button “1”);
- set the thresholds for operation during memorization.
3.4 The test mode "ALARM-TEST" (set with the PDU-L) simulates the alarm
condition. This mode can be reset both with the PDU-L and the power supply of the
detector's receiver. The alarm on the working signal ("true fire") is reset only by
interrupting the power supply of the detector's receiver.
3.5 The test mode "FAULT-TEST" (set with the PDU-L) simulates the fault
condition. This mode can be reset both with the PDU-L and the power supply of the
detector's receiver.
