Estap EM 3000 Smart PDU Installation Notes-2

Estap Smart PDU Installation-2

I will try to explain the installation of the Door Sensor for Estap EM 3000, which I started to introduce last week about Smart PDU.

If you wish, you can integrate these sensors, which are used in alarm systems as magnetic dry contacts, into the Smart Pdu EM3000. For this, the number of doors to be controlled is first determined and the sensor pair is supplied. The sensor has a mercury lamp on one side (the side where the cables enter) and a magnet on the other side. The opened version of the sensor is as follows:

Magnetic Dry Contact Sensor:

The two leads you see on the sensor do not actually represent plus and minus. 12V current flows through the sensor, which works like a simple electric switch. This current is interrupted when a magnetic field is created, that is, when the door is closed, and just like a button is pressed, the Smart PDU detects the interrupted current and interprets that the door is opened.

Thus, according to the programming you make in the PDU, the necessary alarm will be generated and the desired tasks will be triggered. For example, it can be listed such as turning on the lighting, giving an audible siren forward warning.

Magnetic Dry Contact Door Sensor Connections:

I used Cat5 UTP cable for wiring and you can make a connection similar to the colors above. There is no need to explain much anyway. Everything is clearly shown in the diagram above.

An important point; send the Negative (-) lead to the magnetic door sensor. Otherwise, the circuit may not be completed when the distance is long. After the installation in the diagram, the device is powered and after 1-2 minutes it is connected to the web panel.

SENSOR SETTING SCREEN

Sensor Settings>Internal Sensor Settings screen opens on the panel. Here, select Sensor Type Input and INPUT1, INPUT2,….. in the Name field and change the Active field from Passive to –> Active. Then select the Input Type as DOOR from the Input Type option and exit this screen by saving. Optionally, the Alarm options are also marked as Active. Then the door is opened and closed to test the sensors. If there is an alarm, the system is ready.
