Electromagnetic Door Holders

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.

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.

Other features include single or

double-coil floor mounting, surface

mounting and direct wall mount-

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.
