- Identification: Verify that the key is a Simplex B/CAT 30 style key, compatible with your specific fire alarm panel or pull station.
- Inspection: Before each use, visually inspect the key for any signs of damage, bending, or excessive wear. A damaged key may not function correctly or could damage the lock mechanism.
4. Operating Instructions
These keys are primarily used for accessing and resetting Simplex fire alarm devices. Always follow local safety protocols and manufacturer guidelines for the specific device you are operating.
4.1. Accessing Fire Alarm Panels
- Locate the keyhole on the Simplex fire alarm panel.
- Gently insert the Simplex B/CAT 30 key into the keyhole. Do not force the key.
- Turn the key clockwise or counter-clockwise as required by the panel's lock mechanism to open the panel door.
- After accessing, remove the key and store it securely.
4.2. Resetting Pull Stations
- After a pull station has been activated, locate the keyhole, typically on the underside or side of the station.
- Insert the Simplex B/CAT 30 key into the keyhole.
- Turn the key to reset the pull station mechanism. The specific turning direction and extent may vary slightly by pull station model. Refer to the pull station's individual instructions if available.
- Ensure the pull station is fully reset and in its normal, non-alarm state.
- Remove the key and store it securely.
5. Maintenance
Proper maintenance ensures the longevity and reliable function of your Simplex B/CAT 30 style key.
- Cleaning: Keep the key clean and free from dirt, dust, and corrosive substances. Wipe with a dry, soft cloth if necessary. Avoid using harsh chemicals.
- Storage: Store the key in a dry, secure location, away from extreme temperatures and moisture. Keep it separate from other keys to prevent wear and tear.
- Lubrication: Avoid lubricating the key itself. If a lock mechanism is stiff, apply a small amount of graphite lubricant directly into the lock, not on the key.
6. Troubleshooting
If you encounter issues while using your Simplex B/CAT 30 style key, consider the following:

- The lock mechanism may be faulty or jammed. Do not force the key.
- Verify the key is fully inserted.
- Key is stuck in the lock:
- Gently try to wiggle the key while applying slight rotational pressure.
