ATTENTION: Some Pelco-D / -P protocol domes and receivers require an address offset of -1. In
other words, the address assigned to the dome / receiver in the DVR camera menu must be 1 below
the address set in the dome / receiver itself! (i.e. DVR ID: 2, PTZ ID: 3)
2.4 Alarm Input / Output Installation
The EDR1640/1620/920 alarm inputs can be used for recording start or recording rate adjustment.
Furthermore, alarm reactions such as camera switching to monitors, buzzer, e-mail and network alarm
are available. An alarm output relay can be switched if required.
EDR920 provides 9 alarm inputs, EDR1640/1620 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.
Use either the 37-pin Sub-D plug or the included adaptor board for connection.
