摘要
A pair of cantilevered battery-holding retainers (22, 22) resiliently support a battery in a telephone handset-mounted, battery-powered, multi-component intruder alert system. Electrical wires for connecting system components mounted above a conventional telephone-type transmitter to microphone output terminals located at the underside of the transmitter, are routed through a bypass groove (84) extending through the transmitter. A retaining ring (86) retains and confines the wires within the groove.
