Description

The Simplex 4005-9803 is a multifunctional 2-IDC / 2-NAC / Relay Card designed to expand the capabilities of Simplex 4005 Series Fire Alarm Control Panels. Ideal for installations requiring between 8 to 36 IDC zones, this expansion card provides two additional Initiating Device Circuits (IDCs), two Notification Appliance Circuits (NACs), and one programmable relay output for enhanced system flexibility.

Built to integrate seamlessly with Simplex 4005 panels, the 4005-9803 card supports zone-specific detection and notification requirements. It works in tandem with the panel’s microprocessor-based programming and LCD display, allowing full circuit-level custom labelling and annunciation. The relay output can be configured for various control tasks such as elevator recall, door release, or auxiliary notifications.

Featuring surface mount technology and engineered for quick installation, this relay card is an efficient and compact solution for expanding fire alarm systems in commercial, industrial, or institutional facilities.
