3. Product Overview
The Simplex 4099-9005 is a red, dual-action manual pull station. Its addressable nature allows the fire alarm control panel to identify the exact location of the activated station. The dual-action design requires a two-step process for activation: first, pushing in a bar, and then pulling down a handle.

4. Installation
Proper installation is crucial for the reliable operation of the manual pull station.
4.1 Mounting
- Mount the pull station on a standard single-gang electrical box or a compatible surface-mount box.
- Ensure the mounting location complies with local fire codes regarding height and accessibility.
- Secure the pull station firmly to the mounting box using appropriate screws.
4.2 Wiring
- Connect the pull station to the addressable signaling line circuit (SLC) of the fire alarm control panel. Refer to the specific wiring diagrams provided with your Simplex fire alarm control panel for correct connections.
- Ensure proper polarity for all connections.
- All wiring must be installed in accordance with NFPA 70 (National Electrical Code) and NFPA 72 (National Fire Alarm and Signaling Code).
4.3 Address Setting
The 4099-9005 is an addressable device. Before connecting to the SLC, set the unique address for the pull station using the appropriate Simplex programming tool or DIP switches, as specified in the device's technical documentation. Each device on the SLC must have a unique address.

5. Operation
5.1 Activating the Alarm
In the event of a fire or emergency, follow these steps to activate the manual pull station:
- Push In: Firmly push the bar labeled "PUSH BAR" on the front of the station.
- Pull Down: Once the bar is pushed in, pull down the handle labeled "PULL HANDLE" until it latches in the down position.
Activation will send an alarm signal to the fire alarm control panel, initiating the building's alarm sequence.
5.2 Resetting the Pull Station
After an alarm has been activated and the emergency resolved, the pull station must be reset. The Simplex 4099-9005 requires a B-Key for resetting.
- Insert B-Key: Locate the keyhole on the front of the pull station. Insert the B-Key into the keyhole.
- Turn Key: Turn the B-Key clockwise or counter-clockwise (depending on the specific mechanism) to release the latched handle.
- Close Cover: Return the handle to its original, unactivated position and close the front cover.
- Remove B-Key: Remove the B-Key.
The B-Key is considered a tool for maintenance and resetting, not a consumable item. If additional B-Keys are required, they can be ordered using PID: 252-019.
6. Maintenance
Regular maintenance ensures the continued reliability of your Simplex 4099-9005 pull station.
- Visual Inspection: Periodically inspect the pull station for any signs of physical damage, tampering, or obstructions. Ensure the device is clean and clearly visible.
- Functional Testing: Test the pull station's operation according to NFPA 72 and local authority having jurisdiction (AHJ) requirements. This typically involves activating the station and verifying that an alarm signal is received at the fire alarm control panel. Always reset the station immediately after testing.
- Cleaning: Clean the exterior of the pull station with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- B-Key Management: Keep B-Keys secure and accessible only to authorized personnel for resetting and maintenance purposes.
7. Troubleshooting
If you encounter issues with your Simplex 4099-9005 pull station, consider the following:
- Station Not Activating:
- Ensure the dual-action steps (push in, then pull down) are performed correctly.
- Check for any physical obstructions preventing the handle from moving freely.
- No Alarm at FACP After Activation:
- Verify wiring connections to the SLC are secure and correct.
- Confirm the pull station's address is correctly set and unique on the SLC.
- Check the fire alarm control panel for any trouble signals related to the SLC or the specific address of the pull station.
- Station Not Resetting:
- Ensure the B-Key is fully inserted and turned correctly.
- Inspect the internal mechanism for damage or debris that might prevent resetting.
- False Alarms:
- Investigate if the station was accidentally activated or tampered with.
- Ensure the station is properly reset after any activation.
For persistent issues, contact a qualified fire alarm technician.
