Door Controllers

The T8526 Intelligent IP Access Controller is at the heart of the Tensor access control system.

The T8526 features include:

Multiple inputs/outputs – the T8526 controls up to 8 smart card readers (four doors). 16 inputs are available for door or anti-tamper sensors, pushbuttons or alarm inputs. 8 outputs are available for door locks or alarms (2x 2.0 Amp and 2x 0.5 Amp relays with a maximum combined load of 6.0 Amps).

Storage – each T8526 Intelligent IP Door Controller can retain information of up to 30,000 cardholders. Each device also stores 200,000 records of the most recent access events.

Communications – the T8526 uses its integral Ethernet 10/100Mbs connection to send access control updates or alert notifications in real-time to the WinAC.NET software to provide real-time reporting capabilities.

Supported card formats - include EM, HID Prox, MiFare, DesFire and HID iClass.

Alarm connectivity – the T8526 can be connected to both fire and inhibitor alarm systems. In the event of a fire, fail-safe doors will be opened immediately; fail secure doors will remain locked. Access controllers are assigned to alarm or fire zones; all units within the same zone respond to the alarm whilst other zones are unaffected. If an inhibitor alarm is activated, all doors are locked until deactivation. However, designated cardholders with special permissions can gain access during an inhibitor alarm lock-down.

Intruder alarm – the T8526 Intelligent IP Door Controller can be used to arm an intruder alarm. Entry of a PIN combination by a designated cardholder at an arming reader will lock all access points and arm the intruder alarm system. On intruder alarm activation, access is inhibited to everyone apart from designated cardholders.

Biometric verification and identification – T34xx biometric fingerprint readers are available where high-security areas demand irrefutable proof of a person’s identity. Facial recognition can be used as an alternative form of biometric verification or identification. Depending upon the security rules in place, cardholder authentication can be based upon a verified fingerprint/facial reading, scanning of a valid card and entry of a correct PIN code or any combination of all 3 factors.

PIN code support – card types that offer information storage, such as HID iClass, can make use of PIN code authentication. In this scenario, cardholders present their card and then enter a PIN code. The PIN is then verified against the code written to the card’s memory. Matched codes and cards, grant access. Cardholders who fail to enter the correct PIN have their account locked after a configured number of attempts. The PIN is unique to each user.

Internal battery support – access control operation is maintained during any short-term power outages by means of the T8526's internal battery. Application displays and alert notifications inform system users of the battery condition and remaining power.
