Mxl Fire Panel Maintenance Manual
Mxl Fire Panel
An installation of fire alarm systems that serves contiguous and noncontiguous properties, under one ownership, from a proprietary supervising station located at the protected property, at which trained, competent personnel are in constant attendance. This includes the proprietary supervising station; power supplies; signal-initiating devices; initiating device circuits; signal notification appliances; equipment for the automatic, permanent visual recording of signals; and equipment for initiating the operation of emergency building control services. The pseudo point (and module) is a concept that was added to the MXL in order to increase system flexibility in both networked and non-networked systems. As the name pseudo suggests, these are virtual devices (not physical) in the system. These points allow the system programmer to create events in the system (alarms, supervisories, troubles, etc.) based on criteria other than the state change of a real device and are intended to allow the system to generate events that result in information being recorded to an event queue (and therefore are recorded to a printer or other device).

For example, a programmer might insert one of these virtual points on the output of a logic function in a networked system when a remote node has a need to know about the state change of that function. When the function changes state, so will the pseudo point. This results in a local event being generated in the alarm queue at the pseudo points address (assuming an alarm usage has been selected).
In addition to the local event, the event will be transmitted across XNET to other nodes. These nodes can use this alarm as it would an alarm from any other alarm causing point. Although introduced for networked systems (XNET), pseudo points can be applied in variety of MXL installations.
This system can offer typically 32-16000 extensions plus 4000 trunks of various types.
