Field Terminal Module-Large

For more information please send us an email 

 All modules are fitted with a NC tamper contact, which opens when the casing is being opened. The two SAB terminals enable the contact to be connected to the tamper circuit.

The terminals are designated with numbers to facilitate installation work.

In order to create a group of terminals, place the jumper on the pins situated between the chosen terminals (numbers). Placing the jumper on next pins in the immediate vicinity will connect another terminal to the previously created group.

The terminal modules serve the purpose of connecting several electric wires without the use of soldering iron. The MZ-2 and MZ-3 modules are made with the help of jumpers and metal pins, directly connected to individual terminals, which makes it possible to easily create groups of terminals  connected in parallel. However, at the installation designing stage, you should pay close attention to the current which is going to pass through particular jumpers. Their primary purpose is transmission of logic signals. To make passage of larger currents possible between the terminals, they should be interconnected with an external wire. The MZ-1 module has no pins.

The field terminal modules: MZ-1 (small), MZ-2 (medium) and MZ-3 (large) are designed for construction of low-voltage installations, such as alarm and/or intercom systems. They come in two versions which differ in the size of terminal block. The modules having smaller terminal blocks are additionally designated with "S", and those having bigger terminal blocks - with "L".
