Norton Rixson RIX-972H 689 – Frequently Asked Questions

1) Will the Norton Rixson 972H hold a heavy industrial door open on its own?
The 972H delivers 75 lbs of holding force, which is what it will hold against. On a heavy or wind-loaded industrial opening, that number is the deciding spec: if the door needs more than 75 lbs to keep it from drifting closed, this unit will not hold it. It's built for swinging doors in industrial and commercial settings and releases the door automatically when the fire alarm system tells it to.
2) What voltage does the 972H electromagnetic door holder run on, and how much current does it draw?
Four options: 120VAC/60Hz and 24VAC/60Hz both at .150 amp, and 24VDC and 12VDC both at .08 amp. Match the unit to whatever your fire alarm panel or auxiliary power supply puts out before you order. On a low-voltage DC panel the .08 amp draw is what you budget against the panel's remaining auxiliary capacity when you're daisy-chaining several holders.
3) Can an electromagnetic door holder be used in place of a fusible link on a fire door?
That's exactly what the 972H is listed for. It's UL-cUL listed as a substitute for fusible links, and it carries CAL FIRE approval 3550-0047:0013. The practical difference is that a fusible link only drops the door once the air at the link gets hot enough, while the 972H releases the moment a smoke detector, pull station, or other electrically operated switch opens the circuit, so the door closes on smoke rather than waiting for heat.
4) Does an electromagnetic holder like the 972H close the door by itself when it releases?
No. An electromagnetic door holder only holds the door open and lets go on alarm. Something else has to actually pull the door shut, which on a swinging opening means a door closer, and on a rolling or guillotine door means gravity or the door's own drop mechanism. Budget the closer separately when you spec the 972H on a swinging fire door.
5) Do I need to order a left-hand or right-hand version of the Rixson 972H?
No handing to specify. The 972H is non-handed, so one part number covers left- and right-hand swings. That matters for a property manager or MRO buyer stocking spares: a single unit on the shelf covers every opening in the building regardless of swing direction.
6) How do I test a Rixson 972H holder without tripping the building fire alarm?
There's a test button on the unit itself. Pressing it drops the door the same way an alarm signal would, so you can verify the release during a walkthrough or annual inspection without pulling a station or putting the panel into alarm. Beyond that button, release is triggered by smoke detectors, manual pull stations, or any other electrically operated switch wired into the circuit.
7) Is the 972H suitable for an overhead rolling door or a fire damper, or only swinging doors?
Both, per the product data. The 972H is built for swinging door applications and is also rated for industrial applications including overhead rolling doors, guillotine doors, and fire dampers. It's classed as a commercial unit for industrial doors, not a residential holder.
8) What finishes does the Norton Rixson 972H door holder come in?
Five: 689 aluminum, 690 dark bronze, 691 light bronze, 693 flat black, and 696 satin brass painted. These are the standard architectural painted finish numbers, so matching the 972H to existing closers and holders on adjacent openings is usually just a matter of reading the finish code off what's already installed.
