3 Overview

The 4004-9301 (beige enclosure) and 4004-9302 (red enclosure) Fire Alarm Control Panels (hereafter called the 4004R) are standalone
Fire Alarm Control Panels for use with agent release and sprinkler preaction/deluge systems. This chapter provides an overview of the
capabilities and operation of the 4004R.
3.1

Agent Release and Preaction/Deluge systems

Agent release extinguishing systems control fire hazards using wet or dry chemicals, each of which must be specifically designed and
approved for use on a particular fire hazard. Examples of typical extinguishing agents include dry chemical, water mist, foam, CO2,
INERGEN, and so on.
When the 4004R is programmed as an agent release system, it controls release appliances, also known as solenoids, actuators, and so on,
that are connected to a set of storage tanks containing the agent. When an alarm activation is detected, the 4004R activates the releasing
appliances and discharges the extinguishing agent.
Programming the 4004R as an agent release system involves selecting one of the pre-programmed, agent release applications pre-
installed on the 4004R. Single hazard (single area) and dual hazard (two separate areas) versions are available, all of which support
manual release, abort switches, and programmable delay timers. See the next section of this chapter for a complete description of each
application.
3.1.1

Preaction/Deluge sprinkler systems

The most common type of preaction sprinkler system is the single interlock preaction system, which uses a two-phase process for
actuating sprinkler heads.
• Phase 1. Alarm activation of an initiating device attached to the 4004R causes the 4004R to activate the releasing appliance attached to
the sprinkler system's Primary Control Valve. When this valve is open, water flows into the sprinkler pipes, readying the sprinkler system
for the possible activation of one or more sprinkler heads. This is known as preaction.
• Phase 2. Sprinkler heads open in response to a fire condition, releasing water onto the fire area.
Specialized situations sometimes require the use of a double interlock preaction system, in which an automatic initiating device, smoke
or heat detector, and a sprinkler head must operate simultaneously to initiate water flow. This differs from the single interlock system,
where these two actions, initiating device and sprinkler head activation, can occur at different times.
A deluge system uses open sprinklers. Activation of initiating devices releases a deluge valve, producing immediate water flow through
all sprinklers. Deluge applications are typically found in specialized situations, where high-flow, water-based suppression is required.
3.1.2

Combination Agent Release with Preaction Deluge backup

In some areas of the country, Authorities Having Jurisdiction (AHJ's) require building owners to protect critical electronic areas, normally
covered only by Agent Release systems, with a combination of Agent Release (primary) and Preaction Deluge (secondary) systems. Their
concern is that not all fires can be extinguished by the agent. Hence, an additional suppression method is required. This capability and
configuration option is included in the 4004R.
When the 4004R is configured for the combination setting, it works just like one would expect an Agent Release panel to work: a confirmed
fire alarm or manual request starts the process and eventually results in the discharge of a suppression agent. In addition to Agent
Release, the panel also starts the Preaction Deluge process in parallel and takes the panel to Phase 1, as described in the Preaction Deluge
section above. If the Agent Release process is successful in extinguishing the fire, nothing else will happen. If, however, the fire is not
knocked-down, flares up and begins to grow, Phase 2 of the Preaction Deluge process will ensue.
Note: Preaction Deluge for this application would typically be applied as Preaction only. However, the output control is the same as for
Preaction Deluge and both terms are used to describe the operation.

Pre-programmed applications

The 4004R ships from the factory with 13 applications installed in memory. Programming the panel involves selecting an application to use,
as well as an option, such as NAC operation, manual and automatic delays, and/or other site-specific functions.
The panels with software version 1, 2 or 3 have nine applications. The panels with version 4.01 or higher have the thirteen applications
noted above. The first table in
expansion relay operation for those applications, if the "original" relay operation is selected. The table also describes the operation of the
NACs and Releasing Appliance Circuits (RACs) along with the functions of the four Initiating Device Circuits (IDCs), and two Special Purpose
Monitor (SPM) circuits. Refer to
