Detex AO19-3x LH 75.5 AL – Frequently Asked Questions

1) Will the Detex AO19-3 operator work on a double egress pair, where one leaf swings in and the other swings out?
That is exactly what the AO19-3 is built for. It is a low energy automatic operator configured for double egress openings, so both leaves get powered operation on a pair that swings opposite directions. You pick Independent, where each door operates on its own, or Simultaneous, where both leaves run together. Independent is the usual choice for a corridor pair where traffic uses one leaf at a time; Simultaneous suits an opening where the full clear width is needed on every cycle.
2) What door width do I order the Detex AO19-3 automatic operator for?
Three door width options are offered: 75.5 inches, 92 inches, and 100 inches. Measure the full opening across the pair, frame to frame, not a single leaf, and order the option that covers it. The header assembly is sized to the opening, so this is the one dimension you cannot change after the unit ships.
3) What arm do I order for the Detex AO19-3 if my door sits in a deep reveal or I am short on headroom?
Three arm and mounting options cover this. Standard handles a normal reveal. The Deep option is built for an 11 inch reveal on a push type door, which is what you want when the header sets well back from the door face. The Flat Arm substitution buys 1-3/4 inches of additional headroom at the top of the door, so it is the answer when a transom, a soffit, or a low ceiling leaves you tight above the leaf. Measure the reveal and the clearance above the door before you pick.
4) What power does a Detex AO19-3 automatic operator need at the header?
115VAC, single voltage source, plugged in at the header. There is no separate low voltage transformer to run, so the electrical rough-in is one circuit to the header location with enough clearance behind the cover for wiring, ventilation, and later service access. Confirm the circuit capacity before the header goes up.
5) Can I tie a maglock or electric strike into a Detex AO19-3 operator so the door unlocks before it opens?
Yes. The operator has a built-in electric lock relay with an adjustable delay, so it releases an electric strike, maglock, or other electric locking device and waits before driving the door open. That delay is what keeps the motor from fighting a lock that has not dropped yet. The locking device and its own power still get ordered separately.
6) What happens if someone walks into the door while a Detex AO19-3 is closing?
The operator stalls the door during the closing cycle and re-activates to open when it senses an obstruction before latch position. Push and Go is the other side of that behavior: push the leaf manually and the operator takes over and completes the opening, which is how most people with a cart or a wheelchair end up using it rather than hitting an actuator.
7) What finishes does the Detex AO19-3 operator header come in?
Two: AL aluminum and BZ dark bronze. On a fleet of openings the header is a visible band across the top of the frame, so match it to the existing storefront or frame finish rather than to the door hardware. Both finishes are offered across the width and arm choices.
8) Is the Detex AO19-3 operator rated for a high traffic building, or is it a light duty unit?
Heavy-Duty, commercial only. Detex builds the AO19 series for high use and high abuse openings, which is the reason it turns up in hospitals, schools, municipal buildings, and multi-tenant residential where a light duty operator gets torn up in a year. It is not a residential product.
9) Where do I get wiring diagrams and a parts breakdown for a Detex AO19-3 operator?
Detex publishes the full set for the AO19-3: installation instructions in English, a parts list, and separate repair manuals for the push motor/gearbox and the pull motor/gearbox. Programming the reverse on obstruction, Push and Go, power close, and electric lock relay timing is done from those instructions after the unit is powered up. For a maintenance shop stocking spares, the two gearbox manuals are the ones worth having on file.
