The Simplex 4004R is a fire alarm control panel dedicated to suppression release operation, designed to provide reliable monitoring and control for automatic extinguishing, deluge, and preaction applications.
It includes four initiating circuits, two NACs, two RACs, and special-purpose inputs for manual release and abort, making it suitable for equipment rooms and protected areas with extinguishing systems that require clear multi-stage release logic.
The 4004R panel is designed specifically for suppression release applications, combining initiating, notification, and releasing circuits with special-purpose monitoring inputs in one organized solution.
It supports automatic extinguishing release, deluge and preaction sprinkler system release, single or dual hazard area protection, and combined agent release and preaction operation according to the selected configuration.
Initiating circuits can be selected for cross-zoning or activation from a single detection input, with short-circuit RAC supervision and compatibility with listed/approved 24 VDC actuators.
Audible escalation of events provides clear stages from alarm through release timer active to release, while the operator interface provides per-circuit status LEDs and Acknowledge, Alarm Silence, and System Reset functions with mode and timer selections in programming.
By combining IDC, NAC, and RAC circuits, release/abort inputs, multi-mode release logic, and a clear operator interface, the 4004R provides a dedicated and reliable solution for fire suppression releasing systems.
