Sdc 801AL Keyswitch Spdt Single Cylinder

Product Description

The SDC - SECURITY DOOR CONTROLS 801AL is a single-cylinder keyswitch designed to control access-related electrical circuits through a single-pole, double-throw (SPDT) switching configuration. The 801AL accepts a standard key cylinder to mechanically actuate the switch, allowing a technician or security integrator to toggle between two circuit states with a physical key. This type of device is commonly installed in commercial and institutional access control systems where manual override or local control of door hardware, locks, or alarm circuits is required. The SPDT output makes it suitable for both normally-open and normally-closed circuit applications.

The 801AL is used in commercial door access control installations, security panel integrations, and building automation scenarios where key-operated switching is required. It is appropriate for use at entry points, elevator lobbies, and controlled areas where authorized personnel need a tamper-resistant, key-actuated means of enabling or disabling a circuit. Installation is typically performed by a licensed security or low-voltage electrician in accordance with local codes.

Key Features

• SPDT switching configuration supports both normally-open and normally-closed circuit connections
• Key-cylinder actuation provides tamper-resistant, authorized-only control
• Single-unit packaging suitable for individual door or panel installations
• Compact keyswitch form factor fits standard electrical and access control enclosures

Compatibility

Designed as an OEM-style keyswitch for commercial access control and security door hardware applications. Consult SDC - SECURITY DOOR CONTROLS documentation for confirmed compatible door hardware and control panel pairings.

Installation Notes

Installation should be performed by a licensed low-voltage electrician or certified security systems integrator. De-energize all associated circuits before wiring the switch terminals. Follow local electrical codes and the access control system manufacturer wiring diagrams when connecting SPDT terminals. Do not exceed the rated electrical load for the switch contacts.
