GENERAL DESCRIPTION
The router is designated to expand the range of the Fire Alarm System VIT, transmitting the signals between the fire detectors and the other routers or the
Control Panel in the system. Communication between them is based on a high-frequency radio emission. The router has one monitored output for fire
condition, which is intended to control external for the system devices. If the output is assigned to a zone, then on the relative fire phase, the output is
activated and the router switches to “Fire condition” Mode.
The router consists of power supply unit, attached to a metal frame (pos.3, fig.2), and a radio module with external antenna (pos.2, fig.2), mounted into a
plastic box with base (pos.5, fig.2) and cover (pos.7, fig.2). Under the radio module, on the right side, are located the monitored output terminals, for
connection with external devices (pos.2, fig.3).
Built indication, green (pos.1, fig.1), yellow (pos.2, fig.1) and red (pos.3, fig.1) LED provides status information to the router:
- “Network Connection” Mode – Red and yellow LEDs are lights up continuously. The router scans all frequency channels. Upon recognition of a
Control Panel or another router, it submits a request for connection to the network. If the request is confirmed, the router is registered in the configuration of
the Control Panel and switches to “Service” Mode. The router may switch back to ”Network Connection” Mode in case of failed radio connection between it
and another router (The Fire Control Panel);
- “Service” Mode – Green LED, flashing up with different frequency, proportional to the established quality of the connection with the Control Panel or
another router. Upon significant attenuation of the radio signal, the green LED changes to red flashing up LED. This mode checks the quality of the strength
signal between the router and the Control Panel or another router. From the menu of the panel can be adjusted and reviewed the network parameters of the
router;
- “Duty” Mode – Green LED lights up continuously. The router periodically checks the status of the mains supply and the back up battery supply and
sends the status to the Control Panel;
- “Fire condition” Mode – Red LED lights up continuously and output is activated. The router remains in that condition until it receives a fire restart
command from the Control Panel and deactivates the output;
- “Fault condition” Mode – Yellow LED lights up continuously. The router keeps its network functions, but there exist one of the following fault
conditions, displayed on the screen of the Control Panel:
• Interrupted mains or back up battery supply;
• Fault condition in output for power supply (24V);
• Fault in monitored output - short circuit or interruption;
- “Registration” Mode – On the Control Panel is displayed the status of the relative router. This mode is autonomous for the router and operates in
combination with “Service” mode mentioned above. It allows Enable/Disable the registration of new devices through the router and on the same time set
router in “Service” mode;

MOUNTING AND PUT INTO OPERATION
The device is mounted on a wall indoors and the distance from the tip of the antenna to the ceiling must be at least 20 cm.
1. Manufacturer recommendations
1.1 Routers should not be installed in locations distant by more than one barrier (wall) from the Control Panel or another routers. Exceptions to this rule are
permitted in approved working capacity of the team.
1.2. In premises, where there is other devices operating in the frequency range of 2.4GHz, it is necessary to scan and detect the channel of operation of
these devices. This ensures that the Fire Alarm system we use will occupy a channel that will be shared only by its devices.
2. Evaluation of the signal strength
Before proceeding to installation of the router, the place chosen by the installer needs to be carefully evaluated for the signal strength depending on the
previous router or the Control Panel. The “Mainstay” of the wireless fire alarm system is build by the Control panel VIT 01 and router VIT 02.
Evaluation of the signal strength of router shall be performed as follows:
2.1. Provide a Control Panel VIT01 or another router VIT02, connected to Control Panel VIT01.
2.2. Set the device into Mode “Registration” (See Instruction Manual of VIT01).
2.3. Join the antenna.
2.4. Dismantle the cover (pos.7, fig.2) from the base (pos.5, fig.2) by developing the four screws (pos.1, fig.2). Fit the battery (pos.6, fig.2) and join the
wires to the terminals thereof. Red wire to (+) and to blue (-) battery. Yellow LED lights (mains supply). The router booster scans all channels. Allow
registration of the control panel.
2.5. An assessment of the patency of the signal in the "Service" of the router to the installation site without the device is permanently mounted on the
wall. This allows, if necessary, to choose a suitable place for installation.
