The 4004 Fire Alarm Control Panel (FACP) is a general alarm, battery-backed,

electrically supervised system capable of operating two Notification Appliance

Circuits (NACs) and monitoring two Initiating Device Circuits (IDCs) with

expansion capability of up to 8-IDCs. The 4004 FACP is capable of

automatically controlling auxiliary equipment such as fire doors and fans during

a fire condition. The 4004 provide audible and visible indications during Fire

Alarm, Supervisory, or Trouble conditions. If any of these conditions occur, the

system sounds the appropriate notification appliance(s) and flashes the

applicable display (the red “FIRE ALARM ZONE” display for fire alarm zone

indication, the yellow “TROUBLE” display for trouble indication, and the

yellow LED for “Supervisory” operation).

• Acknowledging the alarm immediately silences the panel audible and

causes the display to illuminate steadily.

• Pressing the “SYSTEM RESET” key resets the system and causes the

seven-segment alarm and trouble displays to indicate a dash (-) for

15-seconds; following the dash, the displays go out on a successful

system reset or indicate an existing Alarm, Supervisory, or Trouble

Condition(s).

The 4004 system has “Re-sound” capability. Following a Supervisory alarm or

trouble acknowledgment, another circuit goes into alarm, supervisory, or trouble;

the applicable display flashes; and the signals again operate. Once in alarm, the

system remains in alarm until the device that initiated the alarm is restored to

normal and the panel is reset.

The FACP constantly checks for electrical troubles (power loss, battery

problems, wiring faults, etc.). If a Trouble occurs, the tone-alert sounds and the

yellow trouble display indicate the type of trouble(s) in the system. Another

selectable 4004 feature is an active status reminder, if there is an acknowledged

alarm, supervisory, or trouble condition in the system, the tone-alert sounds

every eight hours for five seconds.

Figure 1 illustrates the physical layout of the cards and the power-limited and

non power-limited wiring areas within the 4004. Printed circuit boards are

joined together in the system by board-to-board connectors or via a wiring

harness connection.
