The Interflex Electronic Lock Cylinder IF15x series represents a sophisticated, yet user-friendly electronic locking solution designed for a variety of access control applications. This series includes models IF151, IF152, and IF153, each offering distinct configurations to suit different security needs. The core function of these cylinders is to provide secure access control using electronic identification media such as badges or key tags, eliminating the need for traditional mechanical keys.
Function Description:
The IF15x electronic lock cylinders are designed for integration with Interflex access control systems, specifically IF6020 and IF6040. This integration allows for seamless utilization of existing employee credentials and data, simplifying access management and enabling convenient analysis of recorded access data. The system facilitates the programming of complex settings to the locking cylinders, enhancing flexibility and control.
The cylinders operate in several modes:
- Short-Time Release: This is the standard operation mode where an authorized credential (transponder card, key, or key tag) is presented to the electronic knob. After "waking up" the knob module by turning it, holding the credential in front of it triggers a visual-acoustic signal sequence, indicating that the knob module is in release mode (typically green). The cylinder remains in release mode for approximately 5 seconds, allowing the door to be opened, after which it reverts to idle mode, becoming "empty" again.
- Daily Release (Toggle Function): This function allows the locking cylinder to be permanently released, meaning the door can be opened and closed without a credential. To activate this, a credential with "Toggle Authorization" is required. After "waking up" the knob module and holding the authorized credential in front of it until two visual-acoustic signal sequences are observed, the cylinder enters a permanently engaged state. To remove this toggle function, the procedure must be repeated.
Important Technical Specifications:
The IF15x series offers different cylinder configurations:

- Key components: Electronic knob side, mechanical knob side, cylinder body, fixing screw, batteries.
- IF152: A double-knob locking cylinder with two electronic knobs (brass, nickel-plated).
- Standard length: 30/35mm (lengths from 65 mm are possible).
- Key components: Two electronic knob sides, cylinder body, fixing screw, batteries.
- IF153: A half cylinder with one electronic knob (brass, nickel-plated).
- Standard length: 30/10mm.
- Key components: Electronic knob side, cylinder body, fixing screw, batteries.
Dimensions (in mm):
- Cylinder: Dimensions for Euro profile locks according to DIN 18254.
- Electronic knob: 40 × 41.
- Mechanical knob (only IF151): 29.5 × 20.
Power Supply:
- Batteries: Two lithium batteries per electronic knob, type CR2, 3 V.
- Battery life: Approximately 10,000 actuations at 20 °C, depending on the reader type.
- Storage life: Approximately four years.
- Operation with empty battery: Possible at any time using an external low-power adapter.
Environmental Conditions:
- Operating temperature: 0 °C to 55 °C.
- Storage temperature: -40 °C to 85 °C.
- Protection Category: IP54 (IP standard, DIN EN 60529).
- Installation location: Suitable for indoor and outdoor areas (depending on product design). For outdoor use, general outdoor conditions must be checked.
Usage Features:
- Easy Installation: The cylinders are delivered fully preassembled, simplifying the installation process.
- Programming: Before initial operation, the knob module must be programmed using a Service Device. All described procedures assume a programmed knob module.
- Mifare Transponders: For Mifare transponder versions, the knob must be "woken up" by turning it before each step.
- Disassembly Card: A disassembly card is used for both installing and disassembling the knob module. This card puts the knob module into a "disassembly mode," allowing for secure attachment or removal from the cylinder body.
- Visual/Audible Signals: The cylinder provides clear visual (LED lights and flashes) and audible (high tone, deep tone, continuous tone) signals to indicate various states, including:
- Woken up/Wait mode
- Credential recognized/not recognized
- Credential authorized/unauthorized
- Credential expired or outside of time model
- Daily release (toggle)
- Time not set, door initialization not set, facility data not set
- Programming mode (start, data transmission, end)
- System card successfully read/written or not
- Manipulation mode enabled
- Reset
- Error conditions (EEPROM fault, coupling error, RTC fault, invalid interrupt, SPI bus errors).
Maintenance Features:
- Battery Warning System: The lock cylinder incorporates a multi-level battery warning system using visual and acoustic signals to indicate when new batteries are required.
- Warning Level 1 (Administrators Only): A brief red LED flash when an administrator's credential (with a service flag) is presented. The lock cylinder performs the desired action after a slight delay. Administrators are advised to change batteries at this level to prevent user inconvenience.
- Warning Level 2: A longer red LED flash and three short signal tones when any credential is presented. The lock cylinder performs the desired action after a delay. Users are prompted to insert new batteries or contact responsible personnel.
- Warning Level 3: A red LED flash and a long continuous tone when any credential is presented. The lock cylinder performs the desired action after a delay that is longer than in warning level 2. Immediate battery replacement or contact with responsible personnel is required.
- Low-Power Adapter: If the batteries are completely empty, an external low-power adapter can be used to supply voltage to the knob module, allowing all functions to be performed. The adapter is inserted, ensuring correct alignment of contact pins with the emergency power contacts of the knob module. An acoustic signal confirms correct alignment and empty batteries.
- Battery Change Procedure:
- "Wake up" the knob module by turning it.
- Hold the battery replacement card in front of the knob module to activate battery replacement mode, unblocking the cover locking pins.
- Push in the locking pins with a battery replacement tool and remove the cover.
- Replace the batteries, ensuring correct polarity (no signal if polarity is incorrect).
- Push in the locking pins and reattach the knob module cover, ensuring the pins engage correctly.
- Exit battery replacement mode by holding the battery replacement card or an authorized credential in front of the knob module.
- (For older firmware versions) Reset the time using a time card.
The Interflex IF15x series provides a robust and flexible access control solution, combining ease of use with comprehensive security and maintenance features.
