General Electric 2727-A-L overhead door contact triple biased

General Electric 2727-A-L overhead door contact triple biased

The contact is specifically designed for use with overhead doors,

including industrial, commercial, and residential applications. It is

compatible with a wide range of door types, including sectional

doors, rolling doors, and overhead garage doors.
Magnetic Operation: The contact operates on the principle of

magnetic sensing. It consists of a magnet and a contact assembly,

where the magnet is attached to the door and the contact

assembly is installed on the door frame. When the door opens or

closes, the magnet’s proximity to the contact assembly triggers the

reed switches, signaling the door’s status.
Durable Construction: The 2727-A-L contact is built to withstand

demanding environments. It is constructed with durable materials

that provide resistance against impact, vibration, and exposure to

harsh weather conditions. This ensures reliable performance and

longevity even in challenging installations.
Surface Mounting: The contact is designed for surface mounting on

the door frame and the door itself. It features a compact and

streamlined design that allows for easy installation and integration

with the existing door structure.Tamper Detection: The contact

includes tamper detection features to enhance security. It can

detect any unauthorized attempt to manipulate or tamper with the

contact assembly, triggering an alarm or alert to notify users of a

potential breach.Versatile Wiring Options: The contact supports

various wiring configurations to accommodate different system

requirements. It can be wired in series or parallel depending on

the application and the desired setup. This flexibility allows for

seamless integration with security, automation, or monitoring

systems.Wide Operating Voltage Range: The contact operates

within a wide voltage range, typically spanning from 3V to 28V DC.

This compatibility with different voltage levels ensures

compatibility with various control panels, security systems, or

automation devices.Terminal Block Connection: The contact

features a terminal block connection, enabling easy and secure

wiring connections. The terminal block allows for efficient and

reliable electrical connections, reducing installation time and

ensuring proper connectivity.Status LED Indicator: The contact is

equipped with a status LED indicator that provides visual feedback

on the contact’s operation. The LED indicator can indicate the

contact’s activation or provide diagnostic information for

troubleshooting purposes.
