44How to use the terminals of the ALARM/CONTROL connectorThese terminals are used for emergency recording, auto time adjustment and when installing a buzzer, a lamp or a similar alarmdevice.The connector to be used should be compatible with the pin array.Pin arrayThe pin array is different from other digital disk recorders. Make surethat the connection is correct referring to the following.Pin No. Signal Operation Remarks1 Alarm output 8 Alarm signal will be supplied at an event occur-renceOpen collector output24 V DC max., –100 mA2 Alarm output 93 Alarm output 104 Alarm output 115 Alarm output 126 Alarm output 137 Alarm output 148 Alarm output 159 Alarm output 1610 N/A11 Alarm reset input Canceling the alarm display Non-voltage make contactinput/5 V pull-up12 Emergency recording input Starting emergency recording signal input13 Signal ground14 Signal ground15 Available disk space warningoutputSignal output for available (remaining) disk spacewarning of the normal recording area/eventrecording areaOpen collector output/24 V DC max., –100 mA16 HDD error output Signal output upon detection of an HDD error17 Camera error output Signal output upon detection of a camera error18 Error output Signal output upon detection of a recorder error19 Outage processing endoutputSignal output upon completion of outage pro-cessingHigh (+5 V to +12 V, max.6.3 mA)20 Time adjustment I/O • According to the signal input from anotherdevice, the time of this recorder will be adjust-ed.
