Transformer Dry Contact Closure Interface Series



The Dry contact closure interface (CTTDR outdoor and the CTTDRPM indoor) provides the ability to interface with virtually any intelligent security solution that has a dry contact closure interface (which most security solutions such as cameras, access control, motion detection etc. have as a standard feature). When an intelligent security solution detects an intruder, it sends a signal to the CAST Lighting transformer and the CTTDR will turn on or off the lights attached to that transformer.


CAST Perimeter® (CTTDR) outdoor or indoor (CCTTDRPM) enables the CAST Perimeter® Total Solution. Integrating with your security systems to automatically trigger and turn on or off the CAST Perimeter® security lights when an intruder is detected.
Use the (CTTDR) or (CTTDRPM) to integrate with security camera systems, motion detectors, lasers, fence-mounted intrusion detection systems and virtually any system which provides a dry contact. CTTDR / CTTDRPM also connects to upgrade your system with CAST Perimeter FlashGlare, a total solution for securing your site perimeter and driving intruders away.


The Dry Contact Closure is a simple interface to enhance your total security solution.
