    Sargent 8574E 32D – Frequently Asked Questions

    1) What happens to the Sargent 8574 exit device when power is lost?
    It stays locked. The 8574 is a fail-secure electromechanical device, so on a power drop the outside trim remains locked and you need a key or mechanical override to get back in. Free egress from the inside is unaffected, since pushing the rail always retracts the rim latch. If your opening needs to unlock on power failure instead (for a controlled entrance that has to release during an outage), a fail-secure device is the wrong choice.
    2) Will a Sargent 8574 fit an aluminum storefront door with a narrow stile?
    That is exactly what it is built for. The 8574 is a narrow stile rim device, so it mounts on the slim vertical stiles typical of aluminum storefront and glass entrance doors. It is not rated for wood doors. Rim mounting means the latch throws into a strike on the frame stop, so it is a single point of latching at the lock edge rather than top and bottom.
    3) Does the Sargent 8574 come in a fire rated version, and does that change the dogging?
    Yes, and it does. You pick Standard or Fire Rated (Less Dogging) when ordering. Fire rated devices are supplied less dogging because a fire door must positively latch every time, so the rail cannot be held down. If you want the pushbar dogged off during business hours, you need the standard rating on a non-rated opening. Electric dogging (option 58) and remote dogging/latch retraction (option 56) are likewise only relevant on the non-fire-rated build.
    4) What voltage does the Sargent 8574 electrified exit device need?
    Order it as either 12V or 24V, and that choice has to match the power supply and the access control panel feeding it. Confirm the supply's current capacity too, because an electrified latch retraction pull is heavier than a simple switch load. Both voltages are available across the device.
    5) Do I have to specify handing when ordering the Sargent 8574?
    Only if you are taking lever trim. The device itself is ordered without handing, but as soon as you select an ET lever trim you must call out RHR (right hand reverse) or LHR (left hand reverse). All exit devices swing out, so the handing you specify is always a reverse hand. If you order the device exit only with no trim, handing does not come into it.
    6) Can I put the Sargent 8574 on a wood door?
    No. The 8574 is not rated for wood door applications, and it is a narrow stile device intended for metal and aluminum entrances. If your opening is wood, look at a device listed for it, such as the Adams Rite 3700 Series fire rated narrow stile rim device or the 8700 Series, both of which are listed as wood door compatible.
    7) Which other electrified exit bars compare to the Sargent 8574 for access-control openings?
    Several electrified rim exit bars sit alongside the Sargent 8574 electro-mechanical fail-secure device. The SDC Spectra S6136 is a 36 inch electrified architectural rim exit device, though it is a wide stile design with a 4 inch stile and a 1-3/4 to 2 inch door thickness range. The Securitron EMB is an electromechanical exit bar listed for 2-1/4 inch doors. Dormakaba also offers an electrified rim 36 inch device with 4908A trim in classroom function. The 8574 is the narrow stile option among these, sized 32, 36, 42 and 48 inch.
    8) My opening is a wide stile hollow metal door - what should I order instead of the Sargent 8574?
    The Sargent 8574 is built for narrow stile openings, so on a wide stile door a wide stile rim device fits the face better. The Von Duprin 22 is a Grade 1 wide stile pushpad rim device, 36 inch, non-handed, for 1-3/4 inch doors. The Corbin Russwin ED5200 is a Grade 1 wide stile rim device in 36 inch that accepts trim, and the TownSteel ED9700 is a 36 inch Grade 1 heavy duty wide stile rim device.
    9) I need a fire rated exit device for a 90-minute opening - what are my options next to the Sargent 8574?
    The Sargent 8574 is offered in a Fire Rated (Less Dogging) build alongside the standard version, so it can be ordered for a fire door. Fire rated rim alternatives include the Dexter ED1000 Series Grade 1 fire rated rim device, the Arrow FS1250 fire rated 32 inch rim device, the Orca OED85 36 inch fire rated rim device, and the Marks USA M9900F in 36 inch and 48 inch. Among fire rated narrow stile choices, the Adams Rite 3700 Series is Grade 1 narrow stile and fire rated.
    10) What device length should I order for a 36 inch door?
    The 8574 comes in 32, 36, 42 and 48 inch rail lengths. Match the length to the door width, not the opening width, and allow for the end cap clearing the hinge stile. The 32 inch size covers narrow leaves; 48 inch is for wide single doors. One note on ordering: the AL alarmed electric option requires a minimum 36 inch door width, so a 32 inch leaf rules that option out.
    11) Is the Sargent 8574 a Grade 1 device?
    Yes, it carries a Grade 1 rating and is a commercial-duty product, not a residential one. Grade 1 is the highest ANSI/BHMA durability tier, which is what most institutional and government specs call for on a main entrance.
    12) What trim do I order with the Sargent 8574 if I want key or lever entry from outside?
    Eight ET lever trim styles are offered: A, B, E, F, J, L, P and W levers. You can also order the device exit only with no outside trim, which suits an exit-only door that nobody enters through. Pick the lever to match the rest of the building's lever design, and remember trim selection triggers the handing call-out. Option 54 adds an internal micro switch inside the ET control if you need the trim itself to report to a panel.
    13) Is the SDC PSB560 or MSB550 a substitute for the Sargent 8574 rim exit device?
    They are not the same class of hardware. The SDC MSB550 is a 36 inch mechanical switch bar that releases an electromagnetic lock, and the SDC SureExit PSB560 is a 36 inch pressure sense bar with tri-failsafe technology - both are switch bars that signal a separate locking device and are listed for narrow or wide stile. The Sargent 8574 is a rim exit device that does its own single-point rim latching, so it secures the opening itself rather than acting as a release for a maglock.
    14) What narrow stile rim device should I spec if I only need exit-only function and no trim or electrification?
    For a plain exit-only narrow stile rim device, the Falcon 19-R is a Grade 1 exit only narrow stile device in 36 inch for 1-3/4 inch doors, the Falcon 1590EO is a Grade 1 exit only narrow stile device at 42 inch, and the BEST 2401 Series is a non-handed narrow stile exit only rim device. The Sargent 8574 can be ordered as exit device only without trim, but it remains an electro-mechanical fail-secure device requiring 12V or 24V power.
    15) How does the Sargent 8574 compare to the Detex 40 Advantex narrow stile device?
    Both are Grade 1 narrow stile rim exit devices for non-wood doors. The Detex 40 Advantex is rated extra heavy duty and is a mechanical device. The Sargent 8574 is the electro-mechanical fail-secure variant of the 8500 Series, so it holds secure on power loss and accepts electric options such as latchbolt monitor, signal switch in rail, remote latch retraction, and electric dogging - functions a mechanical bar does not provide.
    16) I need a 48 inch device for a wide opening - which narrow stile options go that long?
    The Sargent 8574 is offered in 32, 36, 42 and 48 inch lengths, so it covers wide leaves directly. Among comparable long devices, the Cal-Royal A9820 is a 48 inch Grade 1 heavy duty rim exit device and the Corbin Russwin ED3200 is a 48 inch Grade 1 crossbar rim device for 1-3/4 inch doors, though both are non-narrow-stile builds.
    17) Is a Grade 2 rim device like the Cal-Royal 5000 an acceptable swap for the Sargent 8574?
    Only if the specification allows a lower grade. The Cal-Royal 5000 is a 36 inch heavy duty rim exit device with a Grade 2 chassis and a touch bar, and the Cal-Royal 5500 is a 48 inch Grade 2 push bar device. The Sargent 8574 is Grade 1, so on a project drawing calling out ANSI/BHMA Grade 1 the Cal-Royal units will not meet the callout.
    18) What narrow stile alternative uses concealed vertical rods instead of rim latching like the Sargent 8574?
    The Sargent 8574 is a rim device with single-point rim latching to a surface strike. If the opening calls for top and bottom latching with nothing on the face of the frame, the Hager 4601 Series is a 36 inch Grade 1 concealed vertical rod narrow stile exit device, and the Hager 4501 Series is the Grade 1 concealed vertical rod version with a wide stile pushpad.
    19) Do Adams Rite interlocking rim devices work the same way as the Sargent 8574?
    They latch differently. The Adams Rite 8800 Series 30 inch and the EX88 are Grade 1 narrow stile rim devices using starwheel interlocking latching, with the 8800 listed for 1-3/4 to 2-1/4 inch doors and not wood compatible. The Sargent 8574 uses a rim bolt for single-point rim latching and is the electro-mechanical fail-secure design, so strike prep and the electric tie-in are not interchangeable between the two.
    20) What finishes can I get the Sargent 8574 in to match the rest of my storefront?
    Twelve finishes, which is enough to match most existing entrance hardware: 03 bright brass and 04 satin brass (clear coated), 09 bright bronze and 10 satin bronze, the dark oxidized bronze family in 10B oil rubbed, 10BE and 10BL, 20D dark statuary bronze lacquered, 32 bright stainless and 32D satin stainless, plus BSP black suede and WSP white suede powder coat. For aluminum storefront, 32D satin stainless and BSP black are the usual matches to dark and clear anodized frames.
    21) Is the Sargent 8574 quiet enough for a hospital or school corridor?
    Noise was a design consideration here. The rim bolt mechanism on the 8574 is built for quiet operation, which is why it gets specified in healthcare, education and office settings where a banging latch is a complaint. If you are standardizing across a campus, the 8574 sits in Sargent's 8500 Series, so you can hold consistent trim and finish across multiple openings.
