31-0619 – Frequently Asked Questions
1) What power supply do I need for an Adams Rite 31-0619 MLR control board?
The 31-0619 MLR control board runs on 24V DC and pulls up to 850 mA while the latch is actually retracting. Size the supply for that peak, not the idle draw, and remember the peak is per device, so two leaves on a pair of doors means budgeting for both retracting at once off the same supply.
2) My Adams Rite electric exit device stopped retracting the latch. Is the control board the part I need?
If the device is an Adams Rite motorized latch retraction (MLR) exit device and the motor no longer pulls the latch on a signal, the 31-0619 is the replacement control board for that circuit. It is the board that regulates power to the retraction motor, sold on its own as a service part, not the whole exit device and not the motor. Before ordering, confirm you are getting 24V DC to the board, since a failed supply looks the same at the door as a failed board.
3) Will the Adams Rite 31-0619 board work on a non-motorized exit device or an electric strike?
No. The 31-0619 is built for Adams Rite motorized latch retraction exit devices only. A mechanical exit device has no motor for it to drive, and an electric strike is a separate device in the frame with its own power requirement, so this board does nothing for either one. If the device on your door does not have MLR, this is the wrong part.
4) What does the MLR control board actually do in an access control setup?
On a card reader or intercom release, the controller sends a signal and the MLR motor pulls the exit device latch back so the door can be pushed or pulled open without touching the pushbar. The 31-0619 is the board that manages the power going to that motor through the retract and release cycle. That is why it sits in high traffic and access controlled openings, lobby entries, vestibules, tenant suites, where the latch cycles all day off a credential rather than by hand.
5) Is the Adams Rite 31-0619 a complete MLR kit or just the circuit board?
Just the board. The 31-0619 is the replacement Motorized Latch Retraction control board, ordered as a single configuration with no finish, handing, or size choice to make. The motor, the exit device chassis, the power supply, and the wiring to the door are all separate, so if the motor itself is the failure you need more than this part.
6) Do I have to specify handing or a finish when ordering the Adams Rite 31-0619 control board?
Nothing to specify. The 31-0619 comes one way, as the motorized latch retraction control board, with no handing, finish, or length options. It is an internal electronic component, so the door swing and the device finish make no difference to what you order.
