Ensure the door closes reliably from various opening angles without slamming; Consider the building’s usage – high-traffic areas may require a faster closing speed for energy efficiency and security.
Adjusting Latch Speed
The latch speed controls the final portion of the door’s closing cycle, ensuring positive engagement with the strike plate. This is crucial for security and preventing doors from bouncing open. Like closing speed, latch speed is typically adjusted via a separate valve on the closer body, often found near the closing speed control.
Increasing the latch speed (clockwise rotation) provides a firmer, more decisive latching action, ideal for doors requiring a secure closure. Conversely, decreasing it (counterclockwise) softens the latch, reducing impact and noise. Adjust cautiously; excessive latch speed can damage the door or frame. Observe the door’s final movement – it should latch smoothly and positively without slamming or requiring excessive force. Proper latch speed adjustment complements the overall closing speed for optimal performance.
Backcheck Adjustment
Backcheck is a feature that increases resistance to door opening during the last 7-15 degrees of travel, preventing damage to walls and furniture when the door is forced open. It’s particularly useful in high-traffic areas or where doors are prone to being held open momentarily before being released. Adjustment is typically made using a separate valve on the closer body.
Increasing the backcheck (clockwise rotation) provides greater resistance, while decreasing it (counterclockwise) reduces the effect. Start with a minimal adjustment and gradually increase it until the desired level of control is achieved. Excessive backcheck can make the door difficult to open, so careful observation is key. The goal is to prevent door swingback without hindering normal operation. Proper backcheck adjustment enhances door longevity and protects surrounding structures.
Hold-Open Function Adjustment
The hold-open function allows the door to be securely held in an open position, ideal for ventilation, deliveries, or accessibility. This feature is often adjustable, enabling technicians to customize the holding angle. Adjustment typically involves a mechanism within the closer body, often accessed via a setscrew or similar control.
To engage the hold-open, the door is usually opened beyond a specific point, where the mechanism clicks into place. Releasing the hold-open typically requires a manual action, like a push or pull on the door. Adjusting the hold-open angle involves altering the point at which the mechanism engages. Ensure the selected angle doesn’t obstruct traffic flow or violate fire safety regulations. Proper adjustment provides convenience and accessibility while maintaining building security and code compliance.
