Operating Instructions
Initialization of the Access Controller
1. Power off, uninstall the device from the wall and release the anti-remove switch.
2. Keep pressing ESC Exit Button,
3. Keep pressing ESC and power on for 3 seconds
4. Power on: Initialization is completed, buzzer will give a chirp. Then the controller enters into
operation.
Note：Initialization will only change system password into defaulted and other data will not be
changed or deleted.
AC31S2 POWER SUPPLY
The internal parts of AC31S2 series access controller are working under power of +5V,
external DC power requires DC9V¡ DC12V. Switch power is applied in the controller, which
allows maximum voltage of DC15V. Over voltage may cause AC31S2 series to enter
protection mode or damages. There are over-voltage, overheat and over-current protections
in AC31S2 series.

When choosing the power for driving the electric lock, actual power supply capacity and
rated working voltage for the electric lock should be also taken into account;

(1) Using separate power to drive an always-close clock (locking upon powering off)
Warning:
If an always-close lock is connected in the way that an always-open lock does, the
electric lock may be damaged due to constant power supply to the electric lock coil.
(2) Using Separate Power to Drive an Always-open Lock (the lock is open when powered off)
Protection of Electromagnetic Lock
(1) In order to prevent the lock from overheating due to high voltage (if it is too low, the voltage
the strength will not be enough for locking) over an extended period of time, a current limiting
resistor should be series-connected on the power supply end of the lock and an additional
VEOS LTD YOUR TRUSTED SECURITY SYSTEMS PARTNER
starting capacitor should also be added.
A capacitor with low series resistance is required, for it can release
peak value current required by starting. For example, if the lock is started to lock on in case of
+12V, when the resistor is connected, favorable locking status can be maintained when the
voltage is reduced to about +8V.
(2) Power supply time for the electric lock (especially the pulse lock) should be set properly.
For example, as to pulse lock, the power supply time should be set within 0.1-0.5 second in
order to prevent heating from the coil inside the lock.
Programming of the Access Controller
Press ENT and function keys to enter programming mode.
Press ENT, POW ER light (red), OK light (green) and MODE light (orange) are all lit.
Input five-digit system password and you will a chirp from the buzzer. Then POWER light (red),
OK light (green) and MODE light (orange) all go out and the access controller enters system
programming mode.
Note: The password length of 4-8 bit arbitrary figure, if you forget your password, please do
the hardware system initialization, the initial password is 12345
"0" button to open the door to amend delay time (in the programming mode effective)
(1) "0" button.
(2) According to "5" (for 5 seconds delay, delay here range of 1-255
Note:
This Access Controller supports three types of opening mode, namely, card, password and card
plus password.
When the user is inputting password, no card can be read by the controller at the same time.
