View of the device

The rH-AC15S4R4 module is dedicated for integration of F&Home Radio systems with various alarm panels. It has 15 high-resistance analog inputs, 4 low-power relay outputs, and four opto-isolated inputs (5-12 V).

The module measures the voltages on the analog inputs and compares the values with reference levels. Any deviation of an input voltage over 0.6 V up or down with respect to the reference voltage is treated as an event and logic state "1" is generated on the output. When the deviation is less than 0.6 V, the output state is "0". The state of each comparator is signaled by LED located at each input. When the output of a comparator is in logic state "1", the LED is lit. The value of the reference voltage for each input is measured individually and saved for all inputs at the same time by pressing CAL button. The flexibility in setting up the reference voltages enables cooperation with a wide range of motion sensors, with various output voltages.

The symbol of rH-AC15S4R4

The RH-AC15S4R4 module is represented by object that is composed of three segments and additional output. The first segment is composed of 15 output channels, each providing a binary result of comparison with a reference level. In each individual channel, the algorithm compares the input voltage with a reference voltage, based on the physical comparison - when the deviation from the reference voltage is less than +/-0.6 V, the appropriate output generates logical state "0", otherwise the output state is "1".
The second segment is composed of four binary (two-state) inputs and corresponding four binary relay outputs. The inputs control the relays, and the outputs provide information about the states of the respective relays.
The third segment consists of four channels reading information about the state (on/off) of the connected contacts. Shorting or opening a contact changes the logic state at the corresponding output (1/0).
In addition, the module has 'error code' output, generating logical state "1" when the object loses communication with the module. After restarting the communication, the state returns to "0".

Installation diagram

Reading the status of alarm panel via inputs with opto-isolators:
The alarm panel provides the information at OC (open collector) outputs. The form of the signals can be programmed in the panel. They are read by the opto-isolated inputs of the rH-AC15S4R4 module.

Control of alarm panel via relay outputs:
The inputs of alarm panel are activated by momentary shorting to GND. The form of the signals can be set in the panel. The state of the panel can be changed by the rH-AC15S4R4 module via the connected relay outputs. This way the user can quickly arm the alarm system without using a coder, e.g. by pressing a single button.

F&HOME RADIO integrates electrical installations in such a way that the processes of heating, air conditioning, ventilation, lighting, alarm and access control form one efficient system - all for the safety and comfort of the residents. With wireless two-way communication between the central unit (server) and both sensors and actuators, software solutions, as well as remote control of the system that can performed by the users in many ways, the system allows them to manage home energy resources in a manner appropriate to their needs.

In practice, this means the ability to integrate electrical appliances in such a way that a hand gesture can create a romantic light scene in the living room and bedroom, pull down the shutters or blinds and adjust the interior temperature, for example. The option of remote control via the Internet ensures that even after our return from a long journey we are welcomed by the house as if we have never left.
