DDS NSL4 Online Access Control Controller |
|
|
|
The NSL4 is an online controller that is easy to operate and mainly used for low-cost access control solutions.
The NSL4 suits a wide range of applications and can be connected from a single building to remote multi-site locations via TCP/IP, RS485, RS232 or modem. It can store up to 10,000 cardholders.
Easy programming is achieved through the Amadeus online software, providing video monitoring, real-time cardholder monitoring and alarming, map indication, time zones, security levels, anti-passback, and local and ** linkage.
Overview
|
|
•The NSL4 is a 2-door controller, available with keypad or display.
•The NSL4-DBL is a low-cost 4-door solution consisting of two NSL4 controllers housed in a single enclosure.
•The NSL4-DL-ALR is a dedicated NSL4 with a mini keypad and display for easy alarm monitoring. It triggers the relay outputs of other controllers according to the alarm input status.
The NSL4 series can be combined with TPL4 and DS216 to provide a cost-optimized solution.
