1. Introduction
The Sargent 1560 Electromagnetic Surface Mount Door Holder is designed to securely hold fire and smoke barrier doors in an open position. Upon activation of a remote smoke detector, fire alarm system, or other contact device, the electromagnet releases the door, allowing it to close and contain the spread of fire and smoke. This manual provides essential information for the safe and correct installation, operation, and maintenance of your door holder.
2. Safety Information
WARNING: Risk of Electric Shock.
- Always disconnect power to the circuit before attempting any installation, wiring, or servicing of this device.
- Installation must be performed by qualified personnel in accordance with all applicable local and national electrical codes and regulations.
- Ensure the correct voltage supply (120VAC, 24VAC/DC, or 12VDC) is used as specified for the unit. Incorrect voltage can cause damage to the unit and pose a safety hazard.
- Do not operate the device if it appears damaged.
3. Setup and Installation
Proper installation is crucial for the reliable operation of the Sargent 1560 door holder. Follow these steps carefully.
This image displays the main electromagnet unit (left) and the separate armature plate (right), which is designed to be mounted on the door.
- Determine Mounting Location: Identify the desired open position for the door. The electromagnet unit should be mounted on the wall or floor, and the armature plate on the door, ensuring they align perfectly when the door is in the open position.
- Mount the Electromagnet Unit: Securely attach the electromagnet unit to the wall or floor using appropriate fasteners (not included, typically). Ensure the mounting surface is stable and capable of supporting the unit's weight and holding force.
- Mount the Armature Plate: Attach the armature plate to the door. The plate must be positioned so that its face makes full and flush contact with the electromagnet's face when the door is in the desired hold-open position. Adjustments may be necessary to achieve optimal alignment.
- Wiring Connections:
- Ensure power is disconnected at the circuit breaker before proceeding.
- Connect the power supply wires to the terminals on the electromagnet unit. Refer to the specific wiring diagram provided with your unit for detailed connections.
- Verify that the voltage supplied matches the voltage rating of your Sargent 1560 unit (120VAC, 24VAC/DC, or 12VDC).
- All wiring must comply with local electrical codes.
- Test Operation: Restore power to the circuit. Manually open the door to the hold-open position. The electromagnet should engage and hold the door. Activate the fire alarm system or release mechanism to ensure the door releases and closes properly.
4. Operating Instructions
The Sargent 1560 door holder operates automatically once installed and wired correctly.
- Holding the Door: When the door is opened to the position where the armature plate makes contact with the energized electromagnet, the magnetic force will hold the door securely in place.
- Releasing the Door: The door holder is designed to release the door when the power supply to the electromagnet is interrupted. This interruption is typically triggered by:
- Activation of a fire alarm system.
- Activation of a smoke detector.
- Manual activation of a release switch (if installed).
- Upon release, the door will close under the action of its own closing mechanism (e.g., a door closer), preventing the spread of fire and smoke.
5. Maintenance
Regular maintenance ensures the continued reliability and performance of your door holder.
- Periodic Inspection: Visually inspect the electromagnet unit and armature plate at least annually for any signs of wear, damage, corrosion, or loose components.
- Cleaning: Keep the contact surfaces of both the electromagnet and the armature plate clean and free from dust, dirt, paint, or other debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents. A clean contact surface ensures maximum magnetic holding force.
- Wiring Check: Periodically check all electrical connections to ensure they are secure and that the wiring insulation is intact and undamaged.
- Functional Test: Test the door holder's release function regularly (e.g., monthly or as required by local fire codes) by activating the associated fire alarm or smoke detection system to ensure the door releases and closes properly.
6. Troubleshooting
