An alarm system comprising a plurality of intercom apparatuses, each comprising:
- a resilient enclosure, comprising a pair of side walls, a top wall, a bottom wall, a front wall, and a rear wall;
- a mounting means for mounting said enclosure to a support surface;
- a power switch located on an exterior wall of said enclosure in electrical communication with an external power source;
- a voice intercom means in electrical communication with said power switch and located within said enclosure;
- a smoke and heat detection means in electrical communication with said power switch and located within said enclosure;
- and,
- a plurality of indication labels removably located on a front wall of said enclosure;
- wherein said voice intercom means and said smoke and heat detection means of an individual intercom apparatus is in wireless communication with the remaining intercom apparatuses within said system;
- wherein a first voice intercom signal and a first smoke and heat detection signal generated by said individual intercom apparatus is simultaneously transmitted to said remaining intercom apparatuses within said system;
- wherein a second voice intercom signal and a second smoke and heat detection signal generated by any of said remaining intercom apparatuses within said system is transmitted to said individual intercom apparatus,
- wherein each of said plurality of indication labels are used to indicate a specific one of said plurality of intercom apparatuses;
- wherein said voice intercom means further comprises:
- a push-to-talk button located on said front wall of said enclosure and in electrical communication with said power switch;
- a transceiver module in electrical communication with said push-to-talk button;
- a first antenna located on said upper wall of said enclosure and in electrical communication with said transceiver module;
- a microphone located on said front wall of said enclosure and in electrical communication with said transceiver module;
- a speaker located on said front wall of said enclosure and in electrical communication with said transceiver module;
- a channel selector switch located on said front wall of said enclosure and in electrical communication with said transceiver module;
- a volume selector switch located on said front wall of said enclosure and in electrical communication with said transceiver module;
- and, an intercom display located on said front wall of said enclosure and in electrical communication with said transceiver module;
- wherein an indicated value of said channel selector switch corresponds with an indicated value of one of said plurality of intercom apparatuses and with one of said plurality of indication labels;
- wherein said channel selector switch enables communication with a selected one of said plurality of intercom apparatuses;
- wherein a selected channel is displayed on said intercom display when said push-to-talk button is activated;
- wherein a voice input is directed into said microphone and converted into said first voice intercom signal;
- wherein said transceiver module transmits said first voice intercom signal via said first antenna;
- wherein receipt of said second voice intercom signal is received by said first antenna and said transceiver module, converted into an audible sound, and transmitted through said speaker;
- and,
- wherein said volume selector switch selectably increases or decreases a volume transmitted through said speaker.
