ABLOY PROTEC CLIQ is a combination of the proven ABLOY PROTEC mechanical keying system and the CLIQ electronics developed by ASSA ABLOY. ABLOY PROTEC CLIQ offers the perfect synergy between the superior mechanical ABLOY PROTEC and the programming ease and flexibility inherent in electronic cylinders and keys.

Key Features

  • Electronic access control without wiring
  • Easy installation since only the cylinder in the lock needs to be replaced. Not the lock itself.
  • Flexible access permissions
  • IP57 rated CLIQ keys
  • IP68 rated padlocks
  • Access permissions can be updated remotely
  • Easily replaced standard battery
  • Dual security; mechanical and electronic

Software and Management

CLIQ Web Manager is a full feature web based software for managing your ABLOY Protec CLIQ system. CLIQ Web Manager provides easy, secure and flexible management of your CLIQ keys and cylinders.

CLIQ Intelligent Electronics

CLIQ is based on electronics that can be embedded directly inside the key and the core of a cylinder.

A replaceable battery is inserted into the key and serves as the sole power source. The electronic mechanism embedded in the cylinder, is a self-contained unit. This translates into no wiring whatsoever.

Consequently, the intelligent cylinder installs with ease, just like a mechanical cylinder.

Operating Principle

The use of ABLOY PROTEC CLIQ keys and cylinders is nearly the same as the use of a mechanical locking system. The only difference is the visual and acoustic signals given to the key holder when a CLIQ key is inserted in a CLIQ cylinder. The electronics in the key and cylinder cause a small delay of 0.1 seconds before the key can be turned after the key insertion.

CLIQ Key stampings
Key identification stampings are made on the key. One of identifications is a globally unique number.

CLIQ key battery
The battery powers the electronics in the key as well as in the cylinder.

The battery is located under a plastic cover.

Battery specifications:
3V lithium (type CR2450N).
Lifetime is about ten years or 100,000 key operations. CLIQ Connect keys will have a battery lifetime of about one year.

The battery must be replaced when the key starts to indicates low battery. It is possible to make around 50 key operations until the battery is empty once the low battery warning is given.

Speed of the electronic function
CLIQ cylinders can be operated 0.1 seconds after key insertion. A visual and audible indication is given to the key holder when the key can be turned.

Time functions
CLIQ keys have a clock and calendar feature.
A CLIQ key can be programmed to be; always active, active between certain dates or inactive.
It is also possible to set a weekly operation schedule to the key. The calendar allows the administrator to specify up to 50 time periods where the key is granted access throughout the week. Cylinder specific time periods can also be programmed in the key. The key can for instance be programmed to open all cylinders Mon - Fri 8AM - 5PM except for one (or more) cylinder(s) which can only be opened on Saturdays.

The clock has an accuracy of minimum +/- 1 minute per month.

Wall PD
Wall PD is a remote programming device that can program CLIQ keys over an Internet or LAN connection. Wall PDs are typically mounted onto a wall where the key holders easily can update their keys.

RJ45 connection to Ethernet, can be powered over Ethernet (PoE) 
Power supply: 12-24V AC or DC 2W 
Power supply PoE: 42-57 V DC referral to standard IEEE 802.3af 

CLIQ Reader
CLIQ reader is a device used when controlling electrical devices like electrical lock cases, elevators etc. The operation is similar to a CLIQ cylinder except that the key is not turned. The CLIQ reader contains of two parts, an escutcheon which is the visible part and the electronics which is placed in a secure location. The parts are connected with an electrical wire.
CLIQ Readers can also be used as an extension to a Wall PD. The CLIQ Reader can then be located outdoors while the Wall PD is located on the inside of the wall. This solution makes it possible to update CLIQ keys via a Wall PD from an outdoor location.

Power input 12-24 VDC -10 / +15%
Power consumption 60mA
Relay load max. 0.8A 30V AC/DC resist 20W
Maximum length of the wire between the escutcheon and the electronics is 1 meter. The wire should be cut to the proper length. The wire cannot be extended.

Electronic security of CLIQ keys and cylinders
The communication between the cylinder and key is encrypted using a 112-bits 3DES encryption. The coding of the keys and cylinders has been designed so that even in case of a theoretical break of encryption, the security risk is limited to the single component and one time only. The data stored in the keys and cylinders are also encrypted.
All data transferred from the factory to the End User's database and further on via a programming device and a programming key (C-key) to a CLIQ cylinder or key is encrypted as well.

CLIQ products are tested against the ATEX directive.
The entire keying system has to be ATEX approved. Old keying systems cannot to be converted to an ATEX system and ATEX systems cannot be converted to non ATEX system. ATEX keying system is slightly more expensive than normal CLIQ system due to the annual ATEX audit and slightly modified production lines.

CLIQ ATEX products are approved:
Ex ib IIC T4 (for gas)
Ex ibD 21 T135 (for dust)
ATEX approved keys are marked with EX stamping.

Lifetime of the products
The expected lifetime of the electronic products is about seven years. After that the failure rate of any electronic products starts to grow due deterioration of electronic components and overall wear.
