BX-15 is a battery-operated outdoor bell box that deters potential intruders and alerts you to emergencies with loud 102dB siren sound and high-powered strobe light. Enclosed in an IP44 waterproof housing, this series of wireless bell box generates different alarm sounds for fire and burglary to instantly inform users of the type of danger at hand.

BX-15-F1 adopts Climax’s latest RF technology to deliver record-breaking communication range and superb reliability, making the bell box a top choice to protect large residential or commercial premises. Featuring fast RF transmission, F1 model sends signals to control panels speedily without increasing power consumption.
