EXPANDEDSYSTEMMAXIMUM
An example of the maximum expansion of a system
This layout demonstrates the best conguration for
low noise pictures, dependable operation with good
distance of cable runs using CAT5 or drop cable
When designing a large layout of a Look-C Door
Intercom, you can use this topology of a full system
and then remove any camera or monitor not required
The Master Bus (dotted line) is Daisy-Chain wired to
each of the DBC-4S Bus Splitters, which in turn are
Star-Wired to each unit on a branch Bus
Up to sixteen Monitors can be added to a system
This is the maximum amount of monitors identied on
a system by the monitor ID (See DIP Switches)
A maximum of four cameras can be connected to a
system with the addition of a DBC-4S Bus Splitter
Each Camera Station can control a Door strike
To power this system requires an external 24V 5 Amp
High Current Power supply and DPS Power Injector
See each units instruction manual for further details
*Further information available, see Door Strike Info

2 Wire - Cable Information
RECOMMENDEDWIRESOLUTIONS
The maximum distance of the wiring is limited on the Look-C 2-Wire system Using different cables may also affect the maximum distance which
the system can reach The cable caries both video and data plus the power, so It is recommended that you use better quality with larger gauge
for best results over longer distances For relatively short distances, under 20 Meters, the cable choice is less critical
• Twisted pair cable is to be used
• For best Monitor Image results:
Keep runs as short as practical
Use larger gauge quality cable
• Maximum distance is approximately
100 Meters from furthest end to end
• Greater distances may be possible by
use of a DBC-4S as an in-line booster
• 24Vdc is suitable for general installs
Results may be improved with 28Vdc
• Be sure to check termination of items
at end of line (Impedance Switch)
Cable Gauge A B C
Twisted cable 2x0.75 mm
260M 40M 20M
Twisted cable 2x1 mm
270M 50M 30M
Twisted cable 2x1.5 mm
Use as a general guide only. Results may vary depending on application.
See Notes for further assistance in gaining distances and image quality.

Door Strike
EXAMPLESOFDOORSTRIKECONNECTION
• (a) Door Camera Stations can supply power to an electronic lock of Power-On-To-Unlock type with a holding power of no more than 12V
250mA Connection cable should be less than two metres
• (b) For higher power door strikes or longer cabling, an external power source (Local) is required Connection is by dry-contact relay (NO/NC)
Removal of the “Jumper Connector” is required
• (c) The addition of an “Exit Button” is a momentary contact that triggers the door latch for door release
• (d) External Power with “Exit Button” is available
• (2a) Dual Door Strike Connection is available for controlling two door strikes Local power optional (2b)and Exit Button option (2c) or both (2d)
• (e) Power-OFF-To-Release is available and the setting programmed at the monitor Requires external power
• (f) Power-OFF-To-Release Door Strikes x2 (Optional)
• (x) Other options are available See DCU module

Look-C 2-Wire System can control two door strikes per door station These door strikes can be powered by the door station (12Vdc @ 250mA)
or for more current or a higher voltage, you can add an external power source and use the door stations internal relay to activate the door strike
Door strikes are of two types “Fail Secure” is when power is momentarily applied to the strike to allow the door to open (Power-ON-To Release)
“Fail Safe” is when power is always on to hold the door locked, and momentarily switched off to allow the door to open (Power-OFF-To Release)
Release activation is programmed at the monitor for Fail-Secure(Default) / Fail-Safe Activation time is set from 1 to 9 seconds
Exit buttons are usually located on the inside of the premises to allow electronic door release so the person can exit the secured area
Exit buttons are not time delayed and not compatible with Fail-Safe door strikes If these features are required then see the DCU add-on
