20How to use the terminals of the ALARM/CONTROLThe ALARM/CONTROL connectors on the back is used when connecting an external device such as a sensor that outputs alarmsignals or when installing an external alarm device such as a buzzer or a lamp outside.Insert the unarmored cable into the provided terminal plug (12 pin) and then mount it on the ALARM/CONTROL connector on theback.* The cable should be a single or twisted wire with AWG 26~16 and an exposed length of 9 mm {11/32 inches}.ALARM/CONTROLconnector on the back D1 C1D12ALARM/CONTROLC12Cable connections② Tight the screw when the cable isfully inserted into the terminal hole.① Loosen the screw of the desiredterminal on the terminal plug.③ Mount the terminal plug with thecable connected on the ALARM/CONTROL connector socket onthe back.Terminal plug (12 pin)C1 (D1) sidePin arrayPin No. Signal Operation RemarksC1 Alarm output 1 Alarm signal will be supplied at an event occurrence Open collector output24 V DC max., –200 mA max.C2 Alarm output 2 Alarm signal will be supplied at an event occurrenceC3 Alarm output 3 Alarm signal will be supplied at an event occurrenceC4 Alarm output 4 Alarm signal will be supplied at an event occurrenceC5 Time adjustment I/O According to the signal input from the other device,the time of the recorder will be adjusted to the hourbased on the input timeIn addition, the signal is output at the setting timeof the recorder and the time of other equipment isadjusted to the time of the recorderInput:Non-voltage make contact inputOutput:Open collector output24 V DC max., –200 mA max.C6 Preliminary Input/Output 1 These are for future input and output, and cannotbe usedC7 Preliminary Input/Output 2C8 Preliminary Input/Output 3C9 Preliminary Input/Output 4C10 +5 V output +5 V output +5 V±0.5 V, 200 mA max.C11 Signal groundC12 Signal groundD1 Alarm reset input Canceling the alarm display Non-voltage make contact inputD2 Emergency recordinginputStarting emergency recording signal inputD3 Outage detection input Start of outage processing according to the signalinputD4 External recordingmode switching inputChangeover to the external recording mode bythe signal inputD5 Network error output A signal will be output upon detection of a discon-nected Ethernet link or IP expiration of the DHCPOpen collector output24 V DC max., –200 mA max.D6 HDD error output Signal output upon detection of an HDD errorD7 Camera error output Signal output upon detection of a camera errorD8 Recording error output Signal output upon detection of a recording errorD9 Recorder error output Signal output upon detection of a recorder errorD10 Outage processingend outputSignal output upon completion of outage pro-cessingHigh (ON) 5 V DCLow (OFF) 0 V DCD11 Signal groundD12 Signal ground* Refer to the "About the error logs and the network logs" (☞ Operating Instructions (PDF)) for further information about eacherror output.3 Connections (continued)
