Description
The Edwards 1508-AQN5 Door Holder is a surface wall-mounted electromagnetic door holder designed for fire alarm and life safety applications. The Edwards 1508-AQN5 Door Holder keeps self-closing doors in the open position during normal operation and automatically releases them when power is removed by a fire alarm control panel, smoke detection system, sprinkler system, or manual control switch. Therefore, it helps contain smoke and fire while supporting safe building evacuation procedures.
Edwards 1508-AQN5 Door Holder Function
The Edwards 1508-AQN5 Door Holder uses an electromagnet to hold doors open while energized. As a result, doors remain open for normal traffic flow until a fire alarm event occurs. In addition, when power is interrupted, the holder releases the door, allowing the self-closing mechanism to close the opening and help limit the spread of smoke and flames.
Fail-Safe Operation
This door holder is designed with fail-safe operation as a standard feature. Consequently, doors automatically release if power is lost, ensuring that fire doors return to their protective position during emergencies. Moreover, doors may still be opened or closed manually at any time.
Surface Wall Mount Design
The Edwards 1508-AQN5 is designed for surface wall mounting and installs inside a standard single-gang outlet box. Therefore, it is ideal for retrofit projects and applications where flush mounting is not practical. Furthermore, the compact housing supports a clean and professional installation appearance.
Adjustable Swivel Contact Plate
The device includes an adjustable contact plate with a shock-absorbing nylon swivel ball. As a result, the contact plate automatically aligns to varying door angles, ensuring consistent magnetic contact and reliable operation. Additionally, the adjustable design simplifies installation and setup.
Durable Construction
The Edwards 1508-AQN5 Door Holder features a heavy-duty die-cast metal housing finished with durable baked polyester powder coating. Consequently, it provides long-term reliability in commercial, institutional, and industrial environments. Moreover, the unit contains no moving parts and requires minimal maintenance.
