The conventional fire detection system, SM-CS, as well as manage wired devices, has the opportunity to expand the scope and extend their wired lines, interfacing with wireless devices (sensors, input and output modules, push buttons, remote lights, sounders, devices acoustic and optical-acoustic).

This allows to expand with extreme ease the conventional system, allowing the addition of fire detection devices based on bi-directional communication protocol for the monitoring and control of detectors, modules and components wirelessly.

The radio communication complies with European standard EN54-25 and the devices are certified by third party authorized.
The translator module "wire to wireless" is a conventional device that allows you to add a wireless sub-system to a conventional fire. The detectors communicate with the wireless module through bidirectional protocol.

This device is connected directly to a control panel zone.


The module enables to select one of the 7 radio channels (frequencies) available. Through the program scan of radio frequencies provided you can choose a radio channel free or relatively free from other signals (in order to avoid, if possible, channels already in use).

It is possible to configure the system via radio or directly from the keyboard and display of the interface or via a personal computer connected via RS232 using the software supplied. A display and a series of LEDs allow to know the status of the wireless devices connected, in particular we have the following information:
1) a device connected via radio interface that no longer communicates;
2) presence of radio interference voluntary (jamming) performed for the purpose of compromising the exchange of data;
3) reporting the condition of used batteries, devices connected via radio;
4) shows a tampering attempt of a radio device connected to it.

The wireless interface must have an address in the loop, the address of wireless devices will depart from the wireless interface (up to 32 wireless devices).

Technical Notes:

Operating frequency: 868.15 MHz - 869.85 MHz
Maximum number of devices connected via radio: 32
Maximum number of wireless expansion modules can be connected: 7
Operating Range: 200 meters (in open space)

The wireless devices in the field have the same capabilities of their wired counterparts, but the communication between the detector and the central radio and is done through a translator module "wire to wireless" thanks to a bidirectional protocol owner.

It is possible to ascertain the quality of wireless communication of the sensor using the property test in the device. The basis of the flashing LED on the device is easy to verify which of the 4 following possibilities occurs:
1) Communication failure
2) Low level communication
3) Good level of communication
4) Excellent level of communication
It available a test kit whose purpose is to determine the quality of the radio signal coming directly from the coupler wire-wireless or retransmitted from wireless expansion device (repeater) to a specific point of the system where you want to install a wireless device.
