ACSI 1406 POWER SUPPLY, 24VDC, 2 AMP, FOR 1550 ELECTRIC LATCH RET, FIRE ALARM INTERFACE, AUTO OPERATOR INTERFACE
ACSI Series 1400 Power Supplies are designed to provide power/control to electrified door hardware. The Class 2 rated outputs feature overload, over voltage, and short circuit protection. ACSI Series 1400 products are UL Listed and tested to UL 294 standard.
1406 Series only:
Select from independent control of single exit devices from separate inputs (one or two single doors) or sequential operation of two exit devices from a single input (pair of doors).
• Automatic door operator interface
• Fire alarm interface
• Field adjustable latch retraction time delay
• 24VDC, 12VDC* constant voltage outputs
(250mA each)
1406/1426 Power Supplies
ACSI 1406 and 1426 Power Supplies are designed to operate exit devices equipped with ACSI Series 1550 Electric Latch Retraction (required with 1550 Electric Solenoid Latch Retraction).
Provides a separate input for retracting one exit device or two exit devices sequentially without activating the automatic door operator. While the latches are held retracted, the auto-operator can be activated independently from a different input.
1406BB/1426BB Power Supplies with Battery Backup
All the same features as above, but includes built-in battery backup power.
• 4 hours of backup power at full load during AC power failure.
• Standby battery power with a supervised AC failure output and low battery output.
• Supplied with (2) 12V, 7Ah lead acid batteries.
FEATURES
• UL Listed and tested to UL 294 standard
• Class 2 rated outputs
• 2A load capacity
• Overload, over voltage, and short circuit protection

ACSI ACSI-1406-24V – Frequently Asked Questions
1) What exit device hardware does the ACSI 1406 power supply actually run?
The 1406 is built to operate exit devices fitted with ACSI Series 1550 Electric Latch Retraction, and that power supply is required with the 1550 electric solenoid latch retraction. It is not a general-purpose access control supply for strikes or mag locks; the control logic is written around latch retraction. Output capacity is 2A, Class 2 rated, with overload, over voltage and short circuit protection.
2) Can one ACSI 1406 power supply handle a pair of doors, or do I need two?
One 1406 covers a pair. You select either independent control of single exit devices from separate inputs (one or two single doors) or sequential operation of two exit devices from a single input for a pair of doors. Sequential firing is what you want on a pair so both latches do not pull at the same instant.
3) Does the ACSI 1406 tie into the fire alarm and drop the latches on alarm?
Yes, the 1406 includes a fire alarm interface, and a fire alarm relay is part of the unit. That is how the latches release to their mechanically secure state when the alarm panel signals, which is what an AHJ will look for on an electrified egress door.
4) How does the 1406 coordinate latch retraction with a low energy automatic door operator?
The 1406 has an automatic door operator interface plus a separate input that retracts one exit device, or two sequentially, without activating the operator. While the latches are held retracted, the operator can be triggered independently from a different input. That separation is what lets you hold a door unlatched for a delivery or a push-button cycle without swinging it every time.
5) What do I order if the latches have to stay retracted during a power outage?
Step up to the battery backup version. The 1406BB carries all the same features as the 1406 and adds built-in battery backup giving 4 hours of backup power at full load during an AC failure, standby battery power with a supervised AC failure output and a low battery output, and it ships with two 12V 7Ah sealed lead acid batteries. The standard 1406 has no onboard batteries.
6) Is the ACSI 1406 UL listed for access control use?
The Series 1400 power supplies, including the 1406, are UL Listed and tested to the UL 294 standard, with Class 2 rated outputs. UL 294 is the access control system units standard specifiers typically call out on electrified door hardware.
7) Does the ACSI 1406 give me 12VDC as well as 24VDC?
Both. The 1406 provides 24VDC and 12VDC constant voltage outputs at 250mA each for auxiliary devices such as card readers or request-to-exit sensors, and it is ordered by voltage with 12VDC and 24VDC choices. Overall unit voltage is listed as 12/24VDC. Note the 250mA ceiling on those constant voltage outputs; the 2A capacity is for the latch retraction load.
8) Can I adjust how long the exit device latch stays pulled back?
Yes. Latch retraction time delay on the 1406 is field adjustable, so you set the hold-open duration at the board during commissioning rather than ordering a fixed timing.
9) What is the difference between the ACSI 1406 and the 1426 power supply?
Both the 1406 and 1426 are designed to operate exit devices equipped with ACSI Series 1550 Electric Latch Retraction, and both provide the separate input for retracting one or two devices sequentially without firing the automatic door operator. Each is also offered in a BB battery backup version, the 1406BB and 1426BB, with the same 4 hour full load standby.
10) Is the ACSI 1406 suitable for residential door hardware?
It is a commercial product. The 1400 Series is classified for commercial use and the control scheme assumes electrified exit devices, auto operators, and a fire alarm tie-in, which is openings in commercial, institutional, and multi-family buildings rather than houses.
11) Where do I find the wiring and terminal details for the ACSI 1400 Series power supply?
ACSI publishes installation instructions II-1400-02 for the 1400 Series, and the full ACSI product catalog is available as well. Those cover the input terminals, the sequential versus independent configuration, and the auxiliary output connections for the 1406.
