Technical characteristics
Power consumption.
The consumption of the video door entry unit 5721 depends on the device's current mode of operation (with or
without a call in progress).
The mean values of the power input in the typical modes of operation are the following:
• Video door entry unit 5721:
- with a call in progress (video door entry unit on video communication): 175 mA.
- with no call in progress (video door entry unit on stand-by): 60 mA.
• Video door entry unit 5721/D:
- with a call in progress (video door entry unit on video communication): 175 mA.
- with no call in progress (video door entry unit on stand-by): 60 mA.
N.B. The above values are approximate.
Power supplies and other Due Fili (Two-Wire) accessories.
The power supplies and other accessories that can be used for installing the system are those of the Due Fili
(Two-Wire) range; in particular, the following items are recommended:
• 6922 (basic video door entry unit power supply)
• 6923 (additional power supply for entrance panels and monitors)
• 6852 (power supply for additional video cameras)
• 692S (separator for the division of conversation areas)
• 692C (concentrator for connections of up to 4 entrance panels, of which at least one is a video door
entry version)
• 69AM (audio/video interface module for external video camera)
• 69AM/4 (expansion module for 4 video cameras with audio input to be connected to 69AM)
• 692D/2 (active video floor distributor to adapt impedance of video signal)
• 692D (passive video distributor)
• 69RH (digital relay with 2 independent contacts and maximum load of 3A 230V per contact)
• 69PH (digital relay with 2 independent contacts and maximum load of 6A 230V per contact
AC1)
As regards all the technical characteristics (supply voltage, current delivered, power input, description of termi-
nals, etc.), of the above devices, please see the relevant instruction sheets.
