ANSI BHMA A156.15-2001 pdf download AMERICAN NATIONAL STANDARD FOR RELEASE DEVICES – CLOSER HOLDER, ELECTROMAGNETIC AND ELECTROMECHANICAL
SCOPE
1.1 This Standard establishes requirements for door closers combined with hold-open devices or free-swinging door closers combined with releasing devices and includes performance tests covering operational, cyclical and finish criteria.
1.2 Tests described in this Standard are performed under laboratory conditions. In actual usage, results vary because of installation, maintenance and environmental conditions.
1.3 Instructions shall be included with the product requiring the end users to,
(1) test the product after installation in accordance with the manufacturer’s criteria,
(2) periodically test the products in conjunction with the fire alarm system and,
(3) maintain the door closing system in working order.
2. DEFINITIONS
2.1 Adjustable Backcheck: A cushioning feature of a door closer becoming effective between 60 and 85 degrees of door opening.
2.2 Closer Holder Release Device: A floor, door or header mounted closing device connected with separate or integral releasing and fire or smoke detecting devices.
2.3 Electro-Magnetic or Electro-Mechanical Release Device: A wall, floor or door mounted appliance that releases doors from an open position for simultaneous closing upon signal from a smoke detector or other source. Free Swinging Release: A function where the opening and closing control of a door closer is de-energized until a signal is received from a smoke detector or other source when the closer then performs its normal function and closes the door.
2.5 Hold-Open: In this Standard, a device used in connection with a door closer holding the door in an open position against the closing force of the closer. 2.6 Multiple-Point Hold-Open: A hold-open device holding the door in more than one hold-open position without manual adjustment. (Consult manufacturer’s catalogs for ranges of hold-open points available.)
2.7 SinglePoint Hold-Open: A hold-open device holding the door open in one selective position.
3. GENERAL
3.1 These products shall allow swinging doors to close upon receiving a signal in fire or smoke emergencies.
3.2 Upon activation by a signal to the hold-open or free swinging release device, the door shall become self- closing.
3.3 These products shall have been tested and listed for use on fire door assemblies by a Nationally Recognized Testing Laboratory (NRTL) and shall be under a follow-up in-plant inspection service.
