Simplex 4004 Fire Alarm System

Chapter 1: 4004 System Overview

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 up to 8-IDCs. The 4004 FACP can automatically control auxiliary equipment such as fire doors and fans during a fire condition. It provides audible and visible indications during Fire Alarm, Supervisory, or Trouble conditions.

When a condition occurs:

• The system sounds the appropriate notification appliance(s) and flashes the applicable display (red “FIRE ALARM ZONE” for fire alarm, yellow “TROUBLE” for trouble, and yellow LED for “Supervisory”).
• 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. If the reset is successful, the displays go out; otherwise, they indicate any existing conditions.

The 4004 system has a “Re-sound” capability. If another circuit goes into alarm, supervisory, or trouble after an acknowledgment, the applicable display flashes, and signals operate again. The system remains in alarm until the device is restored to normal and the panel is reset.

The FACP continuously checks for electrical troubles (power loss, battery problems, wiring faults, etc.). A “Trouble” condition triggers the tone-alert and the yellow trouble display indicates the type of trouble. An active status reminder sounds the tone-alert every eight hours for five seconds if an acknowledged alarm, supervisory, or trouble condition exists.

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 by board-to-board connectors or a wiring harness.

Environmental

The 4004 operates within the following conditions:

• Temperature: 32-120° F (0-49° C)
• Humidity: UL - 85% relative humidity (non-condensing), ULC - 93% relative humidity (non-condensing)

Ground

The 4004 FACP must be properly grounded. Readings of less than 0.70 VAC must be measured between ground and neutral. A dedicated Earth connection per NFPA 70, Article 250, and NFPA 78 is required. Connect a 12 AWG copper ground wire from the safety ground (electrical distribution panel) to the green grounding screw on the FACP.

Power Input

The 4004 system is designed for 120 VAC, 60 Hz or 220/240 VAC, 50/60 Hz.

Battery Standby

The batteries mount in the 4004 control panel and provide at least 60 hours of standby operation for a fully configured system. Note: 60 hours of standby is based on 10 Ah batteries without four-wire detectors or other non-alarm loads, followed by five minutes in alarm. A fully configured system with 6.2 Ah batteries provides at least 24 hours of standby, followed by five minutes in alarm.

2. Use the “ACK” key to scroll through programming options and the “SYSTEM RESET” key to select configuration options. Refer to Figure 4 for programming selections.
3. Deactivate SW3 to exit program mode. The setup is saved, and the “h” clears. Record the setup in the “CURRENT SETUP” section on the 4004 door panel label.

Figure 4 illustrates programming selections for the number of zones, initiating device point types, City/Dact module presence, Notification Appliances operation, and Annunciator interface presence.

Chapter 4: Operating Instructions

Front Panel Operation

The user interface includes controls and indicators for alarm, supervisory, trouble, power, and alarm silenced conditions (Figure 5).

Indicators and Controls:

• Supervisory LED (Yellow): Indicates a zone programmed as Fire/Supervisory is in a current-limited state (not an alarm). Press “ACK” to view the zone number on the red, seven-segment display.
• Alarm Silenced LED (Yellow): Indicates notification appliances configured “On Until Silence” are off, and an alarm remains in the system.
• AC Power LED (Green): Indicates AC power is applied to the panel.
• Fire Alarm Zone Display (Red, 7-segment): Indicates alarms and supervisories. Displays the zone number for a single zone alarm. For multiple alarms, it scrolls through the zones. A decimal point indicates the start/end of an alarm list. IDCs in alarm are illuminated ('1'-'8'); IDCs in supervisory are illuminated with a dot ('1.'-'8.').
• Trouble Display (Yellow, 7-segment): Indicates IDC, NAC, City Circuit, Power Supply, AUX output, and system trouble conditions. Displays numerals 1-8 for IDC troubles and alphabetically for other troubles (Table 2).

Operator Keys:

• ACK: Acknowledges alarm, supervisory, and trouble conditions. Silences the tone-alert. Performs a lamp test when pressed for 5 seconds (all LEDs and displays turn ON).
• ALARM SILENCE: De-energizes NACs configured as “On Until Silence.” The “ALARM SILENCED” LED turns ON until all alarms are cleared.
• SYSTEM RESET: Removes IDC loop power for 5 seconds. Turns OFF “On Until Silence” and “On Until Reset” signals if all zones are clear. Turns OFF the “Alarm Silenced” LED and annunciator alarm outputs. Displays dashes (-) during reset.

System Initialization (Power-Up)

IMPORTANT: Notify appropriate personnel of power-up.

Normal Power-Up: Apply system power. Panel displays and indicators appear. Tone alert sounds for one second. “AC POWER” LED is ON. Program the system as needed.

Power-Up Trouble Conditions: Panel displays and indicators do not appear. Check fuses or circuit breakers. If power is removed and reapplied after checks, and the system still indicates trouble, contact Simplex.

Supervisory Conditions

A Fire/Supervisory point distinguishes between Fire Alarm and Supervisory conditions. When water is flowing in a sprinkler system, an Alarm is indicated. If a sprinkler or water pump valve is closed, a “SUPERVISORY” condition is indicated. The yellow “SUPERVISORY” LED flashes, and the tone-alert sounds until acknowledged via the “ACK” key. The “SUPERVISORY” LED remains ON steady after acknowledgment.

Walk Test

The 4004 is equipped with Walk Test, activated by SW4 on the System Board. This feature allows one person to test the system.

• Alarm: Indicated with zone code notification over both NACs. Strobes may not indicate zone code if connected.
• Trouble: Indicated by activating NACs for four seconds.
• Walk Test switch is ignored if there is an alarm.
• An upper case “H” on the yellow “TROUBLE” display indicates Walk Test trouble.
• City Circuit activation is not inhibited; disconnect via Disconnect Switches if needed.
• Display and tone-alert function normally.
• Automatic system reset occurs within 30 seconds after Walk Test alarm.
• Subsequent alarms on the same zone cause another zone code.
• A “SYSTEM RESET” is required when exiting Walk Test.

System Testing (Fire Drills)

Fire Drills should be conducted periodically to ensure occupant familiarity with emergency procedures and system functionality. Testing should be directed by the owner and the local Authority Having Jurisdiction (AHJ).

Considerations for testing:

• How the owner and AHJ want the drill performed.
• Whether the building is occupied.
• Which system features are in use.

For systems connected to a city circuit, notify the AHJ. The AHJ determines if the city connection should be disabled during the test. Optional city modules have disconnect switches (SW1, SW2) for disabling city circuits.

To initiate a test, activate an initiating device (pull station, smoke detector). This simulates a real alarm condition.

Emergency Operating Instructions

If the 4004 Fire Alarm System has an Alarm, Supervisory, or Trouble condition, follow these procedures:

• Alarm-Supervisory-Trouble Condition: System indicator flashing, tone ON.
• To Acknowledge: Press “ACK” until tone alert is silenced. Review indicators and summon personnel to investigate.
• To Silence Alarm Signals: Press “ALARM SILENCE”.
• To Restore System to Normal: Press “SYSTEM RESET” within 15 seconds. Dashes appear while reset is in progress.
• Lamp Test: Press “ACK” for 5 seconds.

Chapter 6: 4004 Battery Selection

Battery Selection

60 Hours of Standby Operation (with 10 Ah batteries): Fully configured 4004 system provides at least 60 hours standby, followed by 10 minutes of alarm, when no four-wire detectors or non-alarm loads are connected.

24 Hours of Standby Operation (with 6.2 Ah batteries): Fully configured 4004 system provides at least 24 hours standby, followed by 10 minutes of alarm, when no four-wire detectors or non-alarm loads are connected.

4004 Fire Alarm System with 4-Wire Detectors or Non-Alarm Loads: For systems requiring four-wire detectors or non-alarm loads, use the battery calculation equation in Table 4.

Table 3 provides the Supervisory Current requirements for various modules:

Note: Add all NAC Appliances and IDC Devices for total.

Battery Selection Calculation

Table 4 provides a step-by-step calculation for determining battery requirements:

1. Enter total supervisory current from all cards.
2. Enter total Auxiliary power current draw in standby.
3. Enter total two-wire detector current draw in standby.
4. Sum lines 1, 2, and 3 for total standby current.
5. Enter the required hours of standby.
6. Multiply line 4 by line 5 for total standby Ah requirement.
7. Enter the total NAC/AUX alarm current.
8. Multiply line 7 by 0.083 for five minutes of alarm, or by 0.167 for ten minutes of alarm.
9. Add lines 6 and 8.

Battery Sizing Guidelines:

• If total in line 9 is ≤ 5.1 Ah, use 2081-9272 6.2 Ah batteries.
• If total in line 9 is > 5.1 Ah and ≤ 8.3 Ah, use 2081-9274 10 Ah batteries.
• If total in line 9 is > 8.3 Ah, the 4004 charger cannot charge larger batteries. Consider using the 4004 with a 4009 NAC Power Extender or a 4005 Fire Alarm Control Panel.

Notes:

• Auxiliary loads subtract from the total 4.0 Amps of power available on the 4004.
• Standby current for detectors is listed on their data sheets. Maximum standby current draw for “low current” IDC is 2 mA per zone; for “high current” IDC is 3 mA per zone.
