Frequently Asked Questions
Q: What voltage does the CL 2778892 horn require?
A: The CL 2778892 is a 24VDC horn assembly. It must be connected to a 24-volt DC electrical system. Operating at incorrect voltage will damage the unit or prevent operation. Verify your lift trucks electrical system is 24VDC before installing.
Q: How loud is this horn and what frequency does it produce?
A: The CL 2778892 produces a nominal 400 Hz tone at approximately 110 dB acoustic output. This frequency and output level meets industrial audibility standards for warehouses and manufacturing environments, providing clear warning sound for personnel.
Q: What is the current draw and will my truck electrical system handle it?
A: Maximum current draw is 2.0A at 24VDC during normal operation, with a peak inrush current of less than 5.0A when first activated. Most electric lift trucks are designed to handle this draw. If you have multiple accessories, verify total circuit capacity.
Q: What connector type does this horn use?
A: The CL 2778892 uses dual stud terminals with M5 threads. This is a standard industrial terminal type. Ensure your wiring harness or control panel has compatible M5 stud connections. Adapter cables may be required if your truck uses a different connector type.
Q: Is this horn for continuous or intermittent use?
A: The CL 2778892 is rated for intermittent duty cycle. This means it is designed for periodic use (short bursts) rather than continuous sounding. Extended continuous operation may cause overheating and failure.
