The ESB.1 is a versatile, mains-powered bleeper that gives a distinct audible alert each time it receives a valid signal from an EasySwitch PIR detector or keyfob. It is designed for indoor use only and is compatible with UK mains power sockets. When used with EasySwitch PIR detectors installed on a residential driveway, the ESB.1 bleeper can, for example, provide an audible alert to a person or vehicle entering the detection area of the PIR detector. The ESB.1 bleeper can be used in conjunction with up to 16 transmitters, which can be exclusively or a combination of both ESD detectors or ESF keyfobs. The ESB.1 alert sound is a 5-second ‘bleep’ which can be set to sound only during the day, only during the night, or all the time.
