Abstract

A fire activation module for a fire extinguishing system includes an actuation device that has an instantaneous actuation current draw during a suppression event. First and second power leads are connected to the actuation device and have a current capacity less than the instantaneous actuation current draw. At least one capacitor is connected to the actuation device and the power leads. The capacitor is configured to store electricity from the power leads and discharge the electricity to the actuation device during the suppression event.

First claim

The invention claimed is:

1. A fire activation module for a fire extinguishing system comprising:
an actuation device having an instantaneous actuation current draw during an suppression event;
first and second power leads connected to the actuation device and having a current capacity less than the instantaneous actuation current draw;
at least one capacitor connected to the actuation device and the power leads, the capacitor configured to store electricity from the power leads and discharge the electricity to the actuation device during the suppression event; and
a microprocessor configured to receive a command from a detector and actuate the actuation device in response to the command, wherein the microprocessor having a zone location assignment and configured to read a zone identification element of at least one component within the zone location assignment including the actuation device, the microprocessor providing the command to the actuation device with the zone identification element corresponding to the zone location assignment.

2. The module according to claim 1 , wherein the microprocessor, the capacitor, and the actuation device are integrated with one another into a single module.

3. The module according to claim 1 , wherein the actuation device includes at least one suppressor, and the microprocessor is programmed to actuate the at least one suppressor during a suppression event in response to the command from a predetermined number of detectors which includes the detector.
