5.1.4 Power Supply

IMPORTANT

The database is stored in battery-backed memory and will be preserved whether the controller is

powered or not. This backup will last up to 5 years provided that the controller is normally powered.

The battery, located on the memory module, can be replaced without losing data. This is

recommended every 3 years.

Note

The backup will be preserved for 6 months if the controller is not powered.

AC Supply

AC power, between 85V ac and 250V ac, 50/60Hz, should be supplied to the controller through an

illuminated, unswitched outlet. A right angle IEC plug is supplied for wiring the mains lead.

WARNINGS

1. AN APPLIANCE OUTLET CAN ISOLATE THE UNIT BUT THIS LEAVES THE POWER CABLE

LIVE; THEREFORE, THE ISOLATOR SWITCH MUST BE SWITCHED OFF BEFORE THE

POWER SUPPLY UNIT IS OPENED.

2. THE INSTALLER MUST INCLUDE A LABEL ON THE POWER SUPPLY UNIT INDICATING THE

LOCATION OF THE ISOLATOR SWITCH.

3. A GROMMET MUST BE FIXED TO THE HOLE THROUGH WHICH THE MAINS LEAD WOULD

PASS. THIS IS TO PREVENT THE METAL ENCLOSURE CUTTING THE MAINS LEAD IF THE

LEAD IS PULLED.

Power Indicator

A red LED is situated within the power supply. It is visible through a small hole about 3in/75mm from the

top on the left-hand side of the power supply case.

• If the door controller is operating off the mains supply, whether the battery is connected or not, the

LED will be lit.

• If the mains supply fails and the unit is running from the backup battery, the LED will be

extinguished.

Note

Always power up the controller using the main supply. This will activate the controller battery

charging facility. Once this is done, ac power can be removed and the controller will operate from

battery backup

5.1.5 Lock Output Voltage

The lock output voltage is set for all doors on the controller using a switch accessible through the top

edge of the power supply. The controller has a power supply (4A or 8A) providing a (total) lock output of

48VA and 96VA respectively.

You can “mix and match” locks provided you do not exceed the maximum allowed for the power supply.

5.1.6 Battery Backup

Two 12V 7Ah batteries (if in a fully-charged, good condition) provide approximately 40 minutes of standby

time for a fully loaded system.

A battery charging facility is available that can provide up to 0.5A at 13.8V dc or 0.25A at 27.6V dc.

5.1.6.1 Door Controllers

IMPORTANT

The battery backup voltage must match the lock output voltage, i.e. 12V or 24V. You may use two

12V batteries in series to provide 24V dc.

The capacity of the battery required should be calculated based on:

• The current consumption of the door controller (1A).

• The current consumption of the devices attached to the reader channels (up to 800mA).

• The current consumption of the locks when operating normally (up to 2A each or 1A depending on
