Electric Bolt Lock with Positioning Ball & Adjustable Delay EB235D
EB235D Electric Bolt Lock for Door Access Control
The EB235D electric bolt lock features magnetic sensor activated locking, a positioning ball and an adjustable locking delay. It supports door status signal output and includes an LED lock status indicator.
Positioning Ball for Improved Alignment
The positioning ball helps align the door before the locking bolt extends. This reduces repeated impacts between the door and the bolt, helping extend the lock’s service life.
Adjustable Locking Delay
Choose a locking delay of 0, 3, 6 or 9 seconds using the two DIP switches.
| Locking Delay | Switch 1 | Switch 2 |
|---|---|---|
| 0 seconds | ON | ON |
| 3 seconds | ON | OFF |
| 6 seconds | OFF | ON |
| 9 seconds | OFF | OFF |
Move the switch toward ON to turn it on, or toward the numbered side to turn it off.
Fail-Safe Operation
The lock releases when power is disconnected. Magnetic sensing activates locking when the door is in position.
Door Status Output & LED Indicator
Supports door status signal output for connection to compatible access control systems. The LED indicator displays the locking status.
Recessed Installation
Designed for recessed installation in compatible door and frame assemblies, including suitable framed glass doors. Check the installation space and mounting dimensions before purchase.
