An extremely loud two-tone piezo-electric siren mounted in a sturdy cream plastic case. The electronics which drive the piezo element & give the siren its characteristic sound are contained within the unit on a PCB & the overall frequency range can be varied by means of a preset on this board. Two links A & B are also present which if bridged with solder determine the mode of operation see table. The board is accessible by removing the bottom mounting plate secured by four screws from the main body. Operating Modes Both links open Single tone operation Link A bridged Pulsed high tone Link B bridged Two-tone as supplied Both links bridged Pulsed low tone Specifications Voltage range 6 15 Vdc Current drawn 90m A at 12 Vdc Output level at 12V110d B Leads V red 0V black 150mm Dimensions 52x 42x 27.5mmlugs are 68mm tip to tip Mounting 58mm spacing M3 ...

Two & four-way switch boxes connecting a stereo power amplifier to up to four pairs of speakers as required. In the 2-way version up to two pairs of speakers can be connected to the amplifiers output either separately or simultaneously provided the amplifier is able to drive two loads at once e.g. down to 4andohm so that 8andohm 2 is acceptable. In the 4-way version up to four pairs of speakers can be connected. Switching is by rocker switches on a sloping front panel. Speaker connections are via spring-loaded terminals. ...
