Setup and Installation
Safety Precautions
- Always disconnect power before installing or servicing the device.
- Installation should be performed by qualified personnel in accordance with all local electrical codes and regulations.
- Ensure proper grounding to prevent electrical shock.
Mounting
- Prepare a standard single-gang electrical box for mounting.
- Feed the wiring from the keyswitch through the opening in the electrical box.
- Secure the keyswitch face plate to the electrical box using the provided anti-tamper screws. Do not overtighten.
Wiring
The KP1A features a SPDT switch. The wiring typically involves connecting to a power source (12/24VDC for the LED) and the control circuit for the device it operates (e.g., an electric lock, alarm panel). Refer to the specific wiring diagram provided with your access control system or device for correct connections.
The bi-color LED indicates the status of the keyswitch. Consult your system's documentation for LED color interpretations (e.g., red for locked, green for unlocked).
Note: Incorrect wiring can damage the device or connected equipment. If unsure, consult a professional electrician.
Operating Instructions
The Securitron KP1A is designed for momentary operation, meaning the key must be turned and released to change the state of the contacts.
- Insert one of the provided tubular keys into the key cylinder on the face plate.
- Turn the key to the desired position (e.g., clockwise or counter-clockwise, depending on configuration). The bi-color LED will change color to indicate the new state.
- Release the key. The key will return to its original position, but the electrical contacts will maintain their changed state until the key is turned again.
- To revert to the previous state, insert the key and turn it in the opposite direction, then release.
The "momentarily turning the key changes the state of the contacts" feature ensures that the switch state is toggled with each key turn, providing a simple and effective control mechanism.
Maintenance
The Securitron KP1A keyswitch is designed for minimal maintenance due to its durable stainless steel construction.
- Cleaning: Periodically wipe the stainless steel face plate with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish or internal components.
- Key Cylinder: If the key cylinder becomes stiff, a small amount of graphite lubricant (not oil-based lubricants) can be applied to the key and inserted into the cylinder.
- Inspection: Annually inspect the wiring for any signs of wear, fraying, or loose connections. Ensure the mounting screws remain secure.
Do not attempt to disassemble the key cylinder or internal switch mechanism, as this may void the warranty and damage the unit.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Keyswitch does not respond (no change in connected device state). | No power to the connected device or keyswitch. Incorrect wiring. Faulty connected device. | Check power supply to the system. Verify all wiring connections according to the system's diagram. Test the connected device independently if possible. |
| LED indicator does not light up or shows incorrect color. | No power to the LED. Incorrect LED wiring. Faulty LED. | Ensure 12/24VDC power is supplied to the LED terminals. Check LED polarity and connections. If all connections are correct, the LED may be faulty; contact support. |
| Key is difficult to turn or remove. | Dust or debris in the cylinder. Worn key or cylinder. | Apply a small amount of graphite lubricant to the key and insert into the cylinder. If the issue persists, the cylinder may be worn and require replacement; contact support. |
| Keyswitch state does not toggle consistently. | Internal switch mechanism issue. | Ensure the key is fully inserted and turned firmly. If the problem continues, the internal switch may be faulty; contact support. |
