Specifically designed and manufactured to provide CRYSTAL CLEAR communications to help create a safer work environment, which increases PRODUCTIVITY and lowers the risk of LIABILITY.
Communication is critical to provide workers a way to contact the elevator operator in case of an emergency. When a worker is hurt, seconds count to get medical attention. As a general intercom system, it allows supervisors and workers to locate and communicate with each other, reducing down time tremendously.
The signal transmission is carried out using the protection loop line. The signal is stable and reliable, and special communication cables are not required. The signal line and power line are not connected with high voltage, ensuring system safety.
No electromagnetic wave pollution; no need to apply for radio frequency. Can be used in elevator-intensive construction areas without mutual interference. Features include electronic volume control, squelch function, and three available frequencies for clear voice quality.
Floor Installation: Connect the intercom with the accessory power cable. A dedicated power supply device can drive fewer than twenty units. The protective grounding wire passing through the coupler cannot be grounded in the middle ground.
Lifting Cage Installation: Connect the intercom, call device power supply, and coupler. In the lift cage, the protective ground wire passes through the hole of the coupler and connects with the ground.
| NO | Terminal | Cable Detail | Explanation |
|---|---|---|---|
| 1 | L | Power (blue) | Three core cable |
| 2 | N | Power (brown) | Three core cable |
| 3 | G | Ground (yellow) | Three core cable |
| 4 | -V | Cable shield | - |
| 5 | -V | Negative power (brown) | Four core shielded |
| 6 | +V | Positive power (black) | Four core shielded |
| 7 | +V | Positive power (blue) | Four core shielded |
| Issue | Potential Cause / Explanation |
|---|---|
| Communication Failure | Protective ground wire of the coupler is grounded in the middle, or basket earth wires are not connected. |
| Poor Communication | High resistance caused by ground wiring and/or poor connection points. |
| Motor Interference | Cables require better shielding to isolate from electric motor noise. |
