The EN 54-3 approved Fire-Cryer Solo model FCS/C is a slimline base sounder for discreet mounting under fire detectors. It requires no special wiring and can be retrofitted to existing installations. It is fully synchronised and has an exceptionally low current consumption. The units can be use as a replacement for electronic sounders or bells to broadcast a clear message “Fire emergency. Please remain calm and evacuate the building immediately”.
