Cole Hersee Co 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, and high/low temperature. The dual rates of the alarm tone are approximately 60 and 120 cycles/minute.
Measuring about 2" long, the Dual-Rate Alarm has solid-state construction protected by a molded plastic shell. Designed for 12-volt systems, the alarm fits a standard seal beam connector or Packard connectors, or it accepts individual blade connectors.
