Dual-Rate Alarm

Cole Hersee Company offers its Dual-Rate Alarm for trucks. Connecting to any two remote switches, manual or automatic, the alarm emits an intermittent tone at one of two different rates, audibly identifying the switch. The alarm has hundreds of uses, but typical applications include: headlights, door ajar, low fuel, high/low pressure, high/low temperature, etc., making it an extremely versatile switch.
