IPU 40081 - IRS 2100 (Tailgate Detector) Data Sheet
2Pages

The Irisys IRS 2100 is a powerful addition to access control systems, providingdetection of someone following a valid cardholder through a controlled door. Suitable for use with most access systems it provides an effective means to increase door security. > Increased door security Օ Detects unauthorised entry Enforces use of card/token Օ Improves roll-call accuracy > High detection rate of people tailgating Օ Low False Alarm Rate Unique thermal imaging technology operates in any lighting conditions Օ Relay interface to access control system > Air-Lock option for interlocked doors Օ May be used as Wrong Wayђ detector > The IRS 2100 works in conjunction with an access control system to detect aperson following a cardholder through a controlled door. The Tailgate Detector is based on the Irisys high-accuracy thermal imaging people counting technology, detecting people by their body heat. It operates by receiving a signal from the access system for each valid cardholder accepted at a door and comparing the number of valid cards with the number of people entering. In the event that someone follows a valid cardholder through the door without presenting a valid card/token a tailgate alarm output is generated. > Sound a local buzzer at the door to allow the person tailgatingto be challenged by staff Օ Recordatailgate alarm on the security system to allow daily/weeklyreports to be generated Trigger live CCTV images to be displayed for an operator to action a response Օ Trigger an integrated response for the security system to record tailgate alarm, time/date, cardholder opening door and digital CCTV images of persons entering The IRS 2100 operates with most access control systems requiring onlyasimple relay interface. For the installing engineer the unit is configured using asimple set-up programme. An airlock configuration may be enabled for interlocked door applications. >

Interface: Tailgate Configuration Valid Card Input:Relay pulse:12VDC for >100msGap of >100ms between successive pulses.Input impedance:500k ohmsTailgate Alarm Output:Solid state normally closed relay referenced to 0VRelay rating:30VDC, 100mAAlarm time:10ms, 30ms, 100ms, 200ms,250ms, 500ms, 1s, 2s, 5s (programmable) Tailgate Detection Configuration: In tailgate mode the detector is ceiling mounted on the secure side of the door. Avirtual count line is positioned to detect people entering. A relay input from the access control system provides a pulse for each valid card presented.If more...
