How to update an Olarm MAX's firmware without connecting to a panel
You can update your Olarm MAX firmware in two ways:
- Power up the device without connecting it to an alarm system or energizer
- If already connected to a system, simply disconnect the communication wires
Once powered, the device will connect to the Olarm Cloud and receive the latest firmware update.
Step 1: Cut and strip the relevant sides of the communications cable
Step 2: Only wire the red and black wires to the positive and negative terminals on the Olarm MAX

Leave the yellow and green communication wires disconnected to prevent system detection.
Step 3: Wire the other side of the communications cable to the power terminals of the peripheral
