4. Contenu du colis
Vérifiez que tous les composants sont présents avant de commencer l'installation :
- SDC 1512 Series EMLock Body (Double)
- Armature Plates (2)
- Mounting Hardware (screws, washers, sex nuts)
- Modèle d'installation
- Manuel d'instructions (ce document)
5. Configuration et installation
Professional installation is recommended for optimal performance and safety. Refer to the included installation template for precise drilling and mounting locations.
5.1. Outils requis
- Perceuse et forets
- Tournevis (Phillips et tête plate)
- Ruban à mesurer et crayon
- pinces à dénuder et à sertir
- Multimètre (pour vérifier le volume)tage)
5.2. Mounting the EMLock Body
- Determine the optimal mounting location on the door frame, typically at the top of the door.
- Use the provided template to mark drilling points for the lock body.
- Percez des trous pilotes comme indiqué.
- Securely attach the EMLock body to the door frame using the supplied mounting hardware. Ensure it is level and firmly seated.
5.3. Mounting the Armature Plates
- With the door closed, align the armature plates with the EMLock body. Mark the drilling points on the door.
- Drill holes through the door for the armature plate mounting bolts.
- Install the armature plates using the sex nuts and bolts, ensuring they can pivot slightly to allow for proper alignment with the EMLock body when the door is closed. This slight pivot is crucial for achieving full holding force.
5.4. Câblage
- Route power wiring from your access control panel or power supply to the EMLock body.
- Connect the power wires to the designated terminals on the EMLock. The unit automatically detects 12VDC or 24VDC input.
- If applicable, connect any optional output wires (e.g., door status sensor) to your access control system.
- Vérifiez que toutes les connexions sont bien fixées et correctement polarisées.
6. Mode d'emploi
The SDC 1512 Series EMLock operates by energizing the electromagnet to secure the door. When power is applied, the electromagnet creates a strong magnetic field, attracting the armature plate and locking the door. To unlock, power to the EMLock is interrupted, releasing the armature plate.
- Verrouillage: When the access control system or power supply provides power to the EMLock, the door will be secured.
- Déverrouillage : When power to the EMLock is cut (e.g., by an access control reader, exit button, or fire alarm system), the door will unlock.
7. Entretien
Regular maintenance ensures the longevity and reliable operation of your EMLock.
- Nettoyage: Periodically clean the face of the EMLock and the armature plate with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the finish and performance.
- Inspection: Annually inspect all mounting hardware for tightness. Check wiring connections for any signs of wear or corrosion.
- Alignement: Ensure the armature plate remains properly aligned with the EMLock body. Misalignment can reduce holding force and cause premature wear.
8. Dépannage
| Problème | Cause possible | Solution |
|---|---|---|
| Lock does not engage (door does not secure) | No power to the EMLock Câblage incorrect Armature plate misalignment | Vérifier l'alimentation et les connexions Vérifiez le câblage par rapport au schéma. Adjust armature plate for proper contact |
| Force de maintien réduite | Gap between EMLock and armature plate Debris on contact surfaces Puissance insuffisante | Ensure armature plate floats freely and makes full contact Clean EMLock and armature plate surfaces Vérifier le volume d'alimentationtage et actuel |
| Lock does not release | Power not being cut Stuck armature plate | Check access control system for proper signal to cut power Inspect armature plate for obstructions or damage |
