C-Tec Emergency Only Call Point Button Reset is a button-operated call/reset point capable of generating emergency calls on an 800 Series call system. Onboard reset button cancels emergency calls made from the NC804DE and standard calls made from other devices wired on the same zone (such as ceiling pull units in Ensuite areas). Ideal for use as a reset point for ceiling pull units that will allow a more urgent Emergency call to be made if additional assistance is required. The alarm current is determined by the type of control equipment and number/type of field devices connected to the system.
