The available current for the 2.0A PSU is for readers and auxiliary outputs. The 24Vdc output is used for release devices. A

separate output is provided for battery recharge.

500mA reserved for battery recharge.

If additional power is required, door releases or auxiliary outputs will require a separate external power

supply. For sites that require UL compliance, all additional power supplies used must be power limited, UL

Listed for Access Control Systems and Accessories.

AC Monitor

All database units, door controllers and alarms controllers have an AC monitor input, which enables the

system to generate an alarm or event if power fails.

Information for Expert Planners

This section explains how the figures in Table 2-3 have been calculated, which is useful if you want to re-

calculate the available current for door releases or auxiliary outputs if, for example, the unit does not

contain a NIC4 module or a backup battery. The values have been calculated from the data shown in Table

2-4. For example, for a cabinet fitted with an 8DBC, the current available for readers, ENVS, door releases

and auxiliary outputs is as follows.

8DBC 120mA

2 x NIC4 Module 300mA

8 door bypass relays 160mA

8 door release relays 160mA

I/O Module 10mA

8 auxiliary output relays on 4IN-8OUT I/O Module 160mA

TOTAL CURRENT TAKEN 910mA

Power Supply Board max 12Vdc output (excluding battery) 6000mA

AVAILABLE CURRENT (using 6.5A power supply) 5090mA

Remove any items that are not used, and re-calculate the available current.
