Features  
Very low current draw.  
DH Series  
• Superior holding force and low residual  
magnetisms.  
Electromagnetic Door Holders  
• Durable die-cast metal.  
• High lustre double chrome or brass plating.  
• Dual-voltage AC or DC inputs.  
• Terminal block connections.  
Description  
Gamewell’s DH Series of electro-  
magnetic fire door holders are  
constructed of durable die-cast  
metal finished in high-lustre double  
chrome or brass plating.  
• Single-or double-coil floor, furface, and  
direct mounting (no brackets required).  
• Aircraft-quality DH drill fixture available to  
reduce installation time and costs.  
Other features inclued standard  
dual-voltage AC and DC inputs of  
24 and 120 volts (standard), as well  
as 12 and 24 volts and at 24 and  
220 volts models. While reducing  
stocking requiements, the 24 and  
120 volts model draws only 0.020  
mA at 24 VDC, lowering overall job  
costs.  
• Extension and misalignment rods.  
Listings  
Listings and approvals below apply to the  
DH Series Electromagnetic Door Holders. In  
some cases, certain modules may not be  
listed by certain approval agencies, or listing  
may be in process. Consult factory for  
latest listing status.  
Other features include single or  
double-coil floor mounting, surface  
mounting and direct wall mount-  
• UL Listed:  
ing. No brackets are required.  
The DH Series door holders offer installation using an adhesive template  
assuring alignment without secondary adjustments. Accessories include  
extension and misalignment rods (various lengths) for correct alignment  
between door and wall at distances greater than 12.0" (30.48 cm) and  
misalignment over 4.0" (10.16 cm).  
The aircraft-quality DH drill fixture reduces installation time and provides  
a near-perfect alignment of catch-plate and armature.  
Basic units offer superior holding force and low residual magnetism.  
Models working at 12 and 24 volts and at 24 and 120 volts can operate at  
higher listed voltages, producing holdng forces in excess of 100 pounds  
(45.3 kg) for special applications.  
Standard Application  
Gamewell’s electromagnetic DH Series door holders are designed to hold  
self-closing swinging doors open until energized by a remote sensing device  
responding to smoke, heat, or flames, alarm systems, or a switch. When  
de-energized, the door holder releases the door, enabling it to swing closed  
to check the spread of smoke, heat, or flames. The door holder can also be  
used in other remote door-closing applications as well.  
The units are recommended for automatic area protection against smoke,  
heat, or flames in schools, hospitals, nursing homes, offices, and other  
public buildings of all kinds. Gamewell’s DH Series of electromagnetic  
door holders are specially engineered for easy connection to dectectors,  
sensors, alarm systems, and annunciators.
