Product Description
Call Center Device Intercom Communication Emergency Phone for Hoist Cage
Product Description
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.
Safety First
Mainly used on construction and temporary Hoists/Elevators, it is recommended by OSHA, and also considered the industry standard in the USA, Canada and Australia.
Communications is critical to provide workers a way to contact the elevator operator in case of an emergency. When a worker is hurt or suffers a heart attack, seconds count to get medical attention to that person.
Also as a general intercom system, allowing supervisors and workers to locate and communicate with each other. The down time that it takes to find personnel and to manage workers is reduced tremendously, thereby adding to the profit of the project.

SYSTEM INSTALLATION
Installation instructions for each floor
The installation method of the intercom on each floor can be referenced to the left of the following view. Fit the intercom and connect the intercom with the accessory power cable. Note: a dedicated power supply device can only drive less than twenty. In accordance with the drawings, another port dedicated power supply connected to the junction box, and then connected to the coupler. In the first floor of the construction elevator, the protective ground wire passes through the hole of the coupler, and it is connected with the ground. Important note for installation, in the communication system, the protective grounding wire passing through the coupler can not be grounded in the middle ground.
Installation instructions in the lifting cage of construction hoist
The installation method of the cage intercom see below right view. In accordance with the drawings, connect the intercom, the call device power supply, and the coupler. In the lift cage, the protective ground wire passes through the hole of the coupler, and it is connected with the ground.
