Room for three output relays, one relay included. Input to monitor the status of a switch from a distance. Specifications: • Relay outputs : 240V/5A • Power supply : 12VAC or DC / 300mA.
Assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-40W) with a small tip. • Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections.
Assembly hints 1.3 Soldering Hints : 1- Mount the component against the PCB surface and carefully solder the leads 2- Make sure the solder joints are cone-shaped and shiny 3- Trim excess leads as close as possible to the solder joint REMOVE THEM FROM THE TAPE ONE AT A TIME ! AXIAL COMPONENTS ARE TAPED IN THE CORRECT MOUNTING SEQUENCE ! You will find the colour code for the resistances and the LEDs in the HALG (general manual) and on our website: http://www.velleman.be/common/service.

Connection & manual operation 23. Connection 1. Connect the telephone connections ‘A’ and ‘B’ to the telephone line connections ‘a’ and ‘b’. 2. Connect a transformer or adapter of 12VAC min. 300mA to the AC connections. 3. If required, connect the switching outputs to the devices. The three outputs between L and P are normally open contacts 4. If you want to check the condition of a (dead) switch, it may be connected between the SW terminals. If the switch is closed, the green IN LED will light up. TEL.
Code setting 25. Setting the code See table to set the first digit (CODE1 or decades) and the second digit (CODE2 or units).
Setting the numbers of rings 26. Setting the number of rings Normally the device is set to pick up the phone after ± 8 rings. If, however, you would like the device to pick up the phone sooner (after ± 3 rings), the manual operating push button should be held pressed before switching on the power supply. Output 1 will switch on by way of confirmation.
Use 27. Use ESTABLISHING THE CONNECTION: 1. Call the phone number to which the remote control is connected. 2. After about 3 or 8 rings the remote control will answer. The red "ON LINE" LED on the device will flash. 3. A few seconds after picking up you will hear the condition of the outputs. First de switch input, then output 1, output 2, and output 3 in that order. A double tone indicates that the condition is ON, whereas a single tone indicates that the condition is OFF.
Enclosure 28. Mounting into a housing (Optional) Ø Ø Ø The entire circuit may be built into a plastic housing (e.g. our housing type D30), which will allow the LEDs and the push button to protrude through the front panel (see figure for boreholes and board position). After cutting out the LED frame, the included sticker may be attached to the front panel.
