An alarm unit is adapted to cooperate by radio transmission with a plurality of other such units arranged in a cluster. Each alarm unit includes a radio transmitter and receiver; a modulator for the transmitter and a demodulator for the receiver; an identifying pre-settable switch for identifying the particular alarm unit in the cluster; multiple alarm transducers for identifying a particular one of a plurality of types of alarm; an encoder coupled to the alarm transducers for controlling the modulator, whereby the transmitter can transmit an encoded transmission identifying the particular alarm unit and the particular alarm type; a decoder for decoding the identification of another of the units in the cluster which is transmitting and the type of its present alarm; and a display for displaying the other unit's identification and the alarm type.
