Data logging in a fire alarm system

A fire alarm control panel of a fire alarm system, comprising:

• a casing;
• one or more processors;
• one or more data stores;
• a power supply;
• a data connection;
• and
• a data logger device located within the casing of the fire alarm control panel, the data logger device having one or more data stores and a data interface that is connected to the data connection of the fire alarm control panel, wherein the data logger device is powered by the power supply of the fire alarm control panel, and wherein the fire alarm control panel and the data logger device are configured to reset responsive to the power supply being turned off and turned back on, wherein the fire alarm system comprises one or more detectors communicatively coupled with the fire alarm control panel via a wired or wireless connection, wherein the data logger device is configured to:
• communicate, via the data interface of the data logger device that is connected to the data connection of the fire alarm control panel, with the one or more processors of the fire alarm control panel, to obtain detector values stored in the one or more data stores of the fire alarm control panel;
• and
• log the detector values into the one or more data stores of the data logger device.

A data logging method in a fire alarm system comprising a data logger device located within a casing of a fire alarm control panel of the fire alarm system, the data logging method comprising:

• communicating, via a data interface of the data logger device that is connected to a data connection of the fire alarm control panel, with one or more processors of the fire alarm control panel, to obtain detector values stored in one or more data stores of the fire alarm control panel, wherein the fire alarm system comprises one or more detectors communicatively coupled with the fire alarm control panel via a wired or wireless connection;
• and
• logging the detector values into one or more data stores of the data logger device;
• and
• throttling, by the data logger device, obtaining the detector values, wherein the throttling comprises obtaining a threshold number of detector values per second.

A method of logging detector values from a control panel of a fire alarm system in which the control panel includes a casing, a processor, and a data connection, and the fire alarm system includes detectors, the method comprising:

• placing within the casing of the control panel a data logger device having a logger storage and a data interface;
• connecting the data interface of the data logger device to the data connection;
• closing the casing of the control panel;
• and
• logging detector values from the control panel into the logger storage of the data logger device;
• and
• learning addresses of the detectors by requesting a detector value for each address that is configurable on each addressable loop that is connectable to the control panel, and recording only the addresses which correspond to a detector being present on a connected addressable loop.
