Profile: KT Assemblies Ltd offers quality products for the fire and security industry. Our delay start module is a small compact PCB that on removal of the NC loop will start an adjustable delay time. At the end of this delay a 1A relay will energize a set of contacts. The relay will only deenergize when the NC loop has been restored. Our KMDB document box is an ideal solution to store all documents on site or even in the office. The box comes complete with a lockable cam with 2X keys and removable lid for easy installation with 4X stand off wall mounting points & 1X hook on mounting point.
