Product Description

The heart of the Notifier System 500 Fire Alarm Control Panel is the Central Processor Unit (CPU-500) module which monitors and controls one or two additional user-selected modules.

The System 500 may be configured as a 4, 8, 12, or 16-zone system. In addition, up to eight control points may be added, creating a maximum capacity of 48 points (16 zones and 12 output circuits).

This part is also eligible for a $100 core return refund. After you replace your panel, send us the damaged one and receive a refund back to your credit card, a payment through PayPal, or a store credit.
Please note: All parts should be installed and tested by a certified fire alarm company.
