1. A security system for protecting an area, comprising:
- at least one sensor for sensing alarm conditions and producing a condition signal representative of an alarm condition;
a processor connected to said sensor, said processor having a plurality of levels of security for each said at least one sensor and wherein each of said plurality of levels is associated in relation to user defined modes each such mode having an indication of how said processor will respond to each possible condition signal communicated from each said at least one sensor in the various modes, said plurality of levels being arranged in a prioritized sequence from highest to lowest level of security;
each said at least one sensor being associated with only one of said levels at a time, said levels defining said processor'"'"'s response to any condition signal which may be produced by any of said at least one sensors;
a control panel located within said area, said control panel for modifying said level associated with each said at least one sensor;
an interface for receiving signals originating from outside the protected area for modifying said level associated with each said at least one sensor;
a discriminator connected to said control panel and said interface, said discriminator determining whether a modification to said level associated with said sensor is coming from said control panel or said interface, and prohibiting a lowering of the security level of any of said at least one sensors if coming from said interface.

6. A method of operation of a security system protecting an area having a sensor, a processor having a hierarchy of levels of security associated with the sensor, a memory for storing instructions, an internal control panel for modifying the level associated with the sensor, an interface for receiving signals from outside the area for modification of the level associated with the sensor and a discriminator for determining where a request has originated, comprising the steps of:
-
receiving a request for reduction of the security level associated with the sensor; determining whether said request originated from the control panel or the interface; reducing the level if the request came from within the protected area; denying the request otherwise unless the signal is identified with a predetermined override code and in such event, lowering the security level as per request. - View Dependent Claims (7)
