| INSTALLATION |
| 1. Fix the PULL CORD SWITCH in mounting bracket. 2. The distance between two switch is 30m and combined with Ø3mm plastic coated wire ropes, with moderate tightness. 3. Install supporting rings in every other 2.5m to hold up wire rope, which reduces the gravity to effect the automatic reset. 4. Tie the wire rope end in a tension spring (fixed in a cord clamp) and evenly strain the rope with a tightener on both sides. |
