2 door interlocking module
KSh 3,499
2 door interlocking module is a security device that controls access to a space with two doors, ensuring that only one door can be open at a time. This prevents unauthorized access, tailgating, and piggybacking, creating a secure airlock-like environment. It’s commonly used in high-security areas like banks, prisons, clean rooms, and data centers.
Description
2 door interlocking module is a high security device that control 2 doors in and airlock situation. When used with our Door status range of magnetic locks 2 door interlocking is achieved allowing only 1 door to be open at a time
2 door interlocking module Functionality:
-
Prevents simultaneous door openings:
The core function is to prevent both doors from being open at the same time.
-
Airlock functionality:
Creates a controlled environment similar to an airlock, where one door must close before the other can open.
-
Security Enhancement:
Minimizes the risk of unauthorized entry by ensuring only one door is accessible at a time, discouraging tailgating and piggybacking.
Common Applications:
- High-security areas: Banks, prisons, data centers, and clean rooms.
- Material Airlocks: Controlling access for the transfer of goods or materials.
- Personnel Airlocks: Regulating access for individuals.
- Gowning rooms: Maintaining controlled environments by ensuring only one door is open during gowning procedures.
- Pass Boxes/Throughs: Controlling access to transfer between areas.
- Air Showers: Ensuring proper air shower function before access.
How it works (general principles):
-
Door Sensors:Magnetic door contacts or other sensors detect the open/closed status of each door.
-
Interlock Relay Module:A central module receives input from the sensors and controls the locking mechanisms.
-
Lock Control:The module activates or deactivates electric strikes or magnetic locks to control door access.
-
Timing and Sequencing:
Some modules may incorporate time delays for controlled door release or activation of other devices.
Key Features:
- Input: Typically 12V DC for power and door status signals.
- Output: 12V DC output to control the locking mechanisms.
- Contact Rating: 3 amp contacts at 24V DC or 120V AC, depending on the specific module.
- Compact Design: Modules are typically small, with dimensions like 70 x 60 x 15mm or 73 x 63 x 20mm.
- Compatibility: Can work with various access control devices like pushbuttons, card readers, and biometric devices.
- Optional features: Some modules offer features like door open alarms, ventilation control, or integration with building management systems.
