1 Purpose and Functions
The ACTii AC2717 controller with power supply is a professional and complete solution designed for access control systems. The device integrates a high-efficiency switching power supply with an advanced timer controller, allowing for direct management of electric strikes, electromagnetic locks, and electric bolts without the need for additional relay modules.
The device features a wide input voltage range (110V - 260V AC) and a stabilized 12V DC output voltage with 3A current, which provides enough power to supply most controllers, keypads, RFID readers, doorphones, and video doorphones available on the market. The built-in control circuit allows for precise adjustment of the bolt opening time, which significantly increases the functionality of the entire security system.
Main features:
- ✔ Wide input voltage range: 230V AC (supports 110V to 260V)
- ✔ Stable 12V DC output voltage at 3A current
- ✔ Smooth adjustment of output voltage holding time in the range of 0 - 15 seconds
- ✔ Solid metal construction ensuring durability and safety
- ✔ Ability to directly connect exit buttons, keypads, and GSM modules
- ✔ Integrated short-circuit and overload protection
- ✔ Compatibility with intercom and video intercom systems
Control capabilities:
The power supply allows opening control by receiving a signal from various sources. It can be connected to a standard NO (normally open) button, access keypad, card reader, as well as external relays from smart home systems or GSM modules. Thanks to NC/NO outputs, the device works with every type of electric lock.

3 Installation and Connection
Before proceeding with the installation, ensure that the power supply is disconnected. The device should be mounted in a dry place with adequate air circulation.
Connection terminal description:
- L, N: AC 230V power input.
- +12V, GND: DC output for accessories (e.g., keypads, readers).
- PUSH: Control input for the exit button (shorting to GND activates the relay).
- CONTROL: Control input for intercom systems (trigger signal).
- NO / NC / COM: Relay outputs for electric strike (NO - normally open, NC - normally closed).
Opening time adjustment:
The device housing has a potentiometer used to adjust the holding time of the voltage on the control output.
- Turning clockwise increases the opening time (up to a maximum of 15 seconds).
- Turning counter-clockwise shortens the opening time (down to a minimum of 0 seconds).
4 Safety Instructions
WARNING: Risk of electric shock!
- The device operates at 230V AC. Installation should be performed by a qualified electrician in accordance with applicable safety standards.
- Do not open the device housing while it is connected to the electrical grid.
- The power supply is designed for indoor use only. Protect it from moisture, liquids, and direct exposure to weather conditions.
- Ensure adequate ventilation around the device – do not cover the ventilation holes in the housing.
- If damage to the housing or cables is detected, immediately disconnect the power.
- Do not exceed the maximum output load of 3A. Overloading can lead to damage to the power supply or connected devices.
5 Troubleshooting
| Problem | Possible cause | Solution |
|---|---|---|
| No voltage at 12V output | No AC power or blown fuse | Check the 230V connection and the status of system fuses. |
| Electric strike does not react to button | Incorrect PUSH terminal connection or faulty button | Check continuity of wires between the button and the PUSH and GND terminals. |
| Lock is constantly open | Incorrect use of NC instead of NO output (or vice versa) | Change the lock connection from NC to NO terminal or vice versa, depending on the lock type. |
| Opening time is too short/long | Incorrect potentiometer setting | Adjust the "Delay" potentiometer on the housing. |
