HOW TO SELECT A PRODUCT

ELECTROMAGNETIC DOOR HOLDER/RELEASES

GENERAL INFORMATION

Electromagnetic door holder/releases are designed for virtually any remote door release applications. They must be used in conjunction with closing devices.

• • Fire/smoke barrier doors
• Door releases when tripped by an alarm or smoke detector
• • Private offices
• Door releases when triggered by a remote switch
• • All devices come with a wall/floor portion and a door portion (armature)
• • Circuit normally closed
• • Door portions have screws and plates to accommodate surface and concealed mounting

Features

• • 25-40lbs. holding force, except where noted
• • Fail-safe operation; power failure releases door to close
• • Positive release button initiates closing motion
• • Tri-Volt (120VAC, 24VAC/DC, 12VDC) is standard on models: 980M, 981M, 989, 990M, 994M, 996M, 997M, 998M and 999M - see
• • Spotting template included
• • For 50-55lbs. of holding force on models 980M, 981M, 989, 990M, 994M, 996M, 997M, 998M and 999M, specify model number x 120VAC, 24VAC, 24VDC or 12VDC when ordering. Not available in Tri-Volt coils.

Certifications

• • See individual sections for compliance with ANSI/BHMA A156.15 standards
• • UL-cUL listed
• • Cal Fire 3550-0047:0001 (980M, 981M, 990M, 991M, 996M, 997M, 998M, and 999M)
• • Cal Fire 3550-0047:0110 (993M)

Specifications

All electromagnetic door holder/releases shall be supplied by architectural hardware supplier. All units shall have a single coil to accommodate 12VDC, 24VAC, 24VDC and 120VAC. The coils shall be independently wound, employing a fuse. Armatures will have positive release button.

HOW TO SELECT PRODUCT

ELECTROMAGNETIC DOOR HOLDER/RELEASES

Prior to determining the product you will need to use, begin by looking at the door and perpendicular wall relationship.

• Measure the distance. That will give you the "D" dimension. Select from chart A.

Chart A

If the distance from wall to door is: "D"	Use
7/16" (11)	989
1-13/16" (46)	990M
2-5/8" (67)	997M
3-5/8" (92)	998M
3-3/4" (95)	994M
4-1/8" (105)	996M
4-3/8" (111)	999M
5-1/8" (130)	998M x XK996M
6-5/8" (168) min. distance from wall	980M
6-3/4" distance between doors	981M

900 base has a minimum: 1-1/2" (38mm) extension.

Maximum: 10" using combination of spacers [1/2" (13mm), 3/4" (19mm), etc.] Longer armature projections may encourage abuse and/or the weight of the extended rods will pull off the face of the door.

Chart B

Junction box location should always be as close as possible to the door pull/lever/knob.

A position horizontally farther toward the hinge edge will dramatically lessen the hold open force of the magnet.

A mounting too high on the vertical plane (top of door) will make it more difficult to pull out of hold open.

Refer to Diagram B

• How far is the centerline of the pivot/hinge from the wall? "A" dimension
• What is width of door? "B" dimension
• At what degree is the door opening? If this dimension is more than 100° consult template. The armature has a few degrees of adjustment but, before proceeding verify with the product template
• Dimension "C" is from pivot point to junction box centerline

SCHEMATICS

ELECTROMAGNETIC DOOR HOLDER/RELEASES

SCHEMATICS

Operation Narrative

Doors are to be normally held open. The electromagnetic door releases will be energized with the voltage shown (at right) in the hardware set for this opening. Power shall be controlled by the fire control system. It will interrupt the power if alarmed, causing the doors to be released, thus allowing the door closers to close the doors. When power is restored the magnets will re-energize, permitting the doors to be manually returned to their held open position.
