Inlet 2A.jpg

DC power 24-48V

The unit supplied by 24-48 V (mostly used by Telecom companies). In case the first power input shut down, the system can automatically start to use the second power input. DC 24-48V inputs are isolated from the earth! Customer can use either + or - on the ground.



Sensor ports

Connect sensor by a supplied RJ-11 (6P4C) cable to any sensor port "A1 .. A8". Determination of the sensor type and connection will occur automatically.



Temperature sensor

Temperature sensor is built-in on a board and sticks out on the front panel of the unit for better measurement. Accuracy equals +/- 1°C.



12V outputs

The unit has two 12V 0.25A outputs (electronics relays). E.g. the appliance has the possibility to connect alarm beacons managed by built-in electronic relays.



CAN port

Connecting CAN devices on a common bus allows you to collect data from the sensors with a large area, or from a large distance and to transmit them to the network. VT825 has a LED for CAN bus status indication.



Dry contact inputs

VT805 has 4 dry contact inputs. Can be used together with any contacts, for example with door or window contacts, circuit breakers etc.


Extension: SD card

SD card or USB stick can be used by the system for saving logs.


Extension: GSM modem

VT805 has the possibility to install GSM or USB modem. VT700 GSM modem is mounted and connected inside of master unit. It is used for sending SMS notifications and receiving SMS commands.


VT18 extension (for VT825).jpg

Extension: VT18 (ordered separately)

Board is mounted and connected inside of "VT825 / Monitoring unit". Adds 8 dry contacts (IN), 2 loads (latching relays with LEDs indicators on front panel) & 12V DC power backup terminal. VT825 allows to install either VT18 or VT10, both extension can not be installed at the same time.



1-wire extension.jpg

Extension: "VT10 / 1-Wire board" (ordered separately)

1-Wire board can be installed insideof monitoring unit to connect access reader or accurate temperature sensors. VT825 allows to install either VT18 or VT10, both extension can not be installed at the same time.


IP cameras

Using built-in interface it is possible to add up to four IP cameras. This will allows to view footagefrom surveillance cameras remotely,


USB camera

One USB camera (class Linux UVC Webcam which supports MPEG) can be connected to "USB" port. More USB devices can be connected to one USB port using USB hub.


USB flash drive

USB flash drive can be connected to VT805 using OTG miniUSB cable and can be used by the system for saving logs. More USB devices can be connected to one USB port using USB hub.



LEDs ACT E1 E2 ERROR.jpg

LEDs

"ACT" - indicates appliance status, "E1" - indicates 12V "E1" relay status, "E2" - indicates 12V "E2" relay status, "ERROR»" - indicates error and traffic, "CAN" - indicates BUS status.


Chassis earthing

Chassis external ground earthing, to suppress electromagnetic interference.
