This product is a component of the JABLOTRON JA-100 alarm system. It allows the connection of two magnetic contacts via two independent inputs with the possibility of setting the properties. The module occupies two positions in the system. The detector responds to the condition (it reports activation and deactivation). The product is intended to be installed by a trained technician with a valid Jablotron certificate.

Installation
Choose a location for the module such that the cables to the detectors are up to 3 m long. 



Figure: 1 - snap terminal of the cover; 2 - yellow signal light of failure; 3 - red signal light of activation inputs;

1. Open the cover and take out the plate with electronics (by pressing the snap clip)
2. Pull the cables through the plastic back panel and screw it in the chosen place.

Before connecting the BUS, the system must be disconnected from the power supply. 

3. Replace the electronics and connect the cables to the terminals.

4. If you want to use a balanced loop for higher protection of supply cables of the detectors, connect in the series with the detector a 1k resistor (see the following figure). The function of balancing must be turned on when setting the characteristics. 



5. Continue to follow the installation instructions of the central controller. Basic steps:
a. After power on, the yellow signal light flashes because the detector is not assigned to the system.
b. In the F-Link program on the Peripheral Devices card, select the desired position and start the learning mode with the Read button.
c. Press the tamper switch in the module (7) - this will cause the detector to learn and the yellow signal light will extinguish. Note - the module occupies 2 consecutive positions (each input one). 
6. Close the cover of the module. 

Set module properties
This is done by the F-Link program - card Peripheral devices. At the position of the module (first or second) select the Internal settings. A dialog appears, in which can be set:
Response of the input 1(2): Off - does not respond (the input can be turned off completely), Not balanced - responds to the disconnection of the contact, Balanced - in the series with the contact is classified resistance of 1k. Activation occurs when the resistance drops below 700 Ohms or rises above 1300 Ohms.
Delay of response to run-in: time filter to improve immunity against false triggering - setting of 0.1sec ... 300sec determines, how long the INP1(2) input must be active, before it is activated in the control panel.
Reverse reaction of walk-in: From the factory, the input is set to respond to circuit disconnection (NC). One can also set the reaction to contact making (NO). 
LED indication is on: it allows turning off the red signal light of the activation of each input.
