2.6 Alarm input / output installation
The EDR920/1640 alarm inputs can be used for recording start or recording rate adjustment. Furthermore, alarm reactions such as camera switching to monitors, buzzer,
EDR920 provides 9 alarm inputs, EDR1640 provides 16. All inputs are programmable NO/NC. Inputs have to be switched through dry contacts.
The 4 output relays provide a dry NO/NC contact. All settings are programmed in the ALARM menu.
