Alertifire is a wireless fire alarm system consisting of an extender and fire detectors communicating by means of a radio signal at a frequency of 868 MHz. The extender connects directly to a conventional fire alarm line, from which it receives supply voltage and to which it sends a fire signal when any fire alarm from its radio network is triggered. The extender can be connected to the conventional fire alarm line alone or together with other wired automatic fire alarms of any type and manual buttons. A resistor can be connected to the expander, balancing the line standby current, as well as a second resistor, determining the fire current when a wireless fire detector is triggered by its radio network. By selecting the value of these resistors, the wireless extender can work with conventional control panels of any type and manufacturer, as well as connect to addressable fire alarm systems using the adapter provided with the relevant address system for the inclusion of conventional fire alarms.

When the wireless smoke detector detects smoke in the protected object, it lights up a red indicator, turns on the built-in siren, and transmits the signal via radio channel to all elements connected in its radio network (extender and fire detectors). The wireless extender immediately transmits the signal to the fire alarm panel via the conventional fire alarm line, and the wireless fire detectors that receive the signal activate their sirens with a delay of 0 to 30 seconds after the start of the signal from the fire detector that registered the event. This state of the radio network is preserved until manual or automatic reset of the fire detector that emitted the fire signal.

● Compatibility with all types of fire alarm and security systems.

● Creates a wireless network with up to 32 fire detectors. Technically, more than 32 fire detectors can be connected to the wireless extender if the relevant regulatory framework allows this.

● Availability of one button, through which the organization of the network and the testing of the fire detector are carried out.

● Availability of self-return to working mode function

● Presence of an LED indication visualizing the operating modes of the fire detectors and expander
