Norton Rixson RIX-972U 689 – Frequently Asked Questions

1) Can the Norton Rixson 972U be used in place of a fusible link on an overhead rolling door?
That is exactly what the 972U is listed for. It is UL-cUL listed and CAL FIRE approved under 3550-0047:0013 as a substitute for fusible links in industrial applications, covering overhead rolling doors, guillotine doors, fire dampers and self-closing windows. Instead of waiting for heat to melt a link, the holder drops the door on a signal from a smoke detector, pull station, test button or other electrically operated switch.
2) What voltage does the Rixson 972U electromagnetic door holder run on, and how much current does it draw?
Four options: 120VAC/60Hz at .150 amp, 24VAC/60Hz at .150 amp, 24VDC at .08 amp, and 12VDC at .08 amp. The DC versions draw about half the current of the AC ones, which matters when you are sizing a fire alarm panel's auxiliary power or a battery backup for several holders on the same circuit. Pick the voltage that matches the releasing circuit you are tying into before you order.
3) Is the 972U a door closer, or does it only hold the door open?
It only holds and releases. The 972U is an electromagnetic holder/release, not a closer, and it has no spring or hydraulic function of its own. The door or damper needs its own closing mechanism, gravity drop, or self-closing device; the magnet simply keeps it in the open position until power is cut by the fire alarm signal or the test button.
4) Will the 972U work on a standard swinging office door?
It is built for industrial overhead applications, not swinging doors. The 972U is specified for overhead rolling doors, guillotine doors, fire dampers and self-closing windows in commercial and industrial settings. For a swinging fire or corridor door you want a wall-mounted or floor-mounted electromagnetic door holder from the Rixson holder line instead.
5) Do I need to order a left hand or right hand version of the 972U?
No handing to specify. The 972U is non-handed, so one unit works regardless of which way the opening swings or rolls. That also means a property manager stocking spares only needs one part on the shelf for every opening in the building.
6) How does the 972U release, and can I test it without triggering the fire alarm?
Release happens when holding current is interrupted, which can come from a smoke detector, a manual pull station, another electrically operated switch, or the unit's own test button. The built-in test button lets a facilities crew verify drop function during routine inspection without pulling a station or putting the alarm panel into alarm.
7) What do I need to have in place before an electrician installs the 972U?
Power at the matching voltage (120VAC, 24VAC, 24VDC or 12VDC) run to the mounting point, a supervised releasing circuit from the fire alarm or detection system to interrupt that power, and clearance at the mount for wiring access, ventilation and future service. Kill the circuit before you land any wires, then commission by testing normal hold, each release trigger, and the tie-in to the connected fire safety system.
8) What finishes does the Rixson 972U come in?
Five: 689 aluminum, 690 dark bronze, 691 light bronze, 693 flat black, and 696 satin brass painted. These are painted architectural finishes, so matching existing closers or holders on adjacent openings is usually straightforward; 689 aluminum is the standard catalog finish.
