Trouble Shot System. System Normal upon Arrival. There are 19, 194 Fixed Heat Detectors in attic. Checked all 19 Heat Detectors for signs of water damage. No damage present. However found some wiring staples that had penetrated outer wiring jacket, but did not see any penetrations through the actual wire touching the copper. I can not rule out the wiring yet. I have strapped out the module removing the heat detector wiring from the module. (Will check back in a week from now if there has been any alarms or troubles with the attic heat Detectors) if there’s an Alarm then the module will require replacement. If not then we will quote time and labor and material to replace the wiring in the attic to all the heat Detectors.
