🚨 False Alarm Fix 🚨

We recently had a job troubleshooting a false alarm caused by issues with the fire panel. Here’s what we found:

✅ Zone Problem: All 3 hand pulls (except one) set off the alarm. The confusion was that Zone 1 includes both hand pulls and heat detectors.

🔌 Wiring Issue: The north side of the building had disconnected wiring, making the job more complicated.

🛠️ Missing Hand Pull: One hand pull was completely missing, with wires never connected. We fixed it!

🔔 Hornstrobe Issue: The hornstrobe wasn’t wired in at all. We spliced it, and it’s working now!

🔥 Heat Detector Issue: The furnace heat detector had water damage over time. It’ll need to be replaced.

💡 Tips:
- Mount detectors above ground to avoid water damage.
- Test wiring connections to clear faults.

Stay safe! 🛠️

🔧 Motion Sensor Troubleshooting: A Step-by-Step Guide! 🔧

If you're experiencing issues with motion detection zones or need to upgrade your system, here’s a simple breakdown of how to troubleshoot and get things running smoothly again!

Step 1: Identify the Faulty Motion Sensors
If you're noticing that certain motion zones are not working properly, the first thing to check is whether the sensors are receiving power. In this case, a specific zone would fault when people walked by but clear after. After testing, it was clear that the wiring was the issue.

Step 2: Inspect and Replace Wires
We needed to replace the motion sensor and run a new wire to ensure a secure connection. Once the wire was properly connected, everything started functioning as it should!

Step 3: Check and Fix Loose Connections
In some cases, a loose connection can cause malfunction. For example, we experienced a zone not working correctly because the ground at the panel was loose. After tightening the connection, the zone started working properly.

Step 4: Replace Broken or Outdated Sensors
Sometimes, sensors just need to be replaced. Another zone was working with a broken dual-tech sensor, and another motion sensor was extremely old. These needed to be swapped out for new, fully functional ones.

Step 5: Confirm Everything is Working Properly
Once the sensors are replaced and wires are secured, be sure to do a full system check. In this case, after everything was wired up and reset, we tested each zone and confirmed that all zones were functioning properly.

Bonus Tip: Power Cycle and Reset
Sometimes, a quick power cycle and resetting the system can help with any lingering issues.
