Product Q&A
Q:What is the effective range of the intercom system?
A:
The effective range is more than 300 meters, provided the conductor loop resistance is less than 600 ohms.
Q:Why might communication fail?
A:
Communication failure can occur if the protective ground wire is grounded in the middle ground or if the ground wire in the hanging basket is not connected properly.
Q:What causes poor communication or interference?
A:
Poor communication is often caused by high resistance from ground wiring, poor connections, or interference from electric motors requiring better cable shielding.
Q:How many frequency channels are available?
A:
The system offers three multiple frequency channels: 250KHz, 741KHz, or 800KHz.
Q:Is the system suitable for extreme weather?
A:
Yes, the heavy-duty composite Nylon Plastic enclosure allows the system to operate in extreme weather conditions.
