Keyscan Inc. A Member of the Kaba Group – CA150 Rev. B Installation Guide (07.15)
About Powering the CA150
The CA150 single door control unit can be powered from one of the following sources:
network switch with power over Ethernet (PoE) capabilities
mid-span PoE injector
+12V DC UL approved power supply
Refer to page 58 for more about power connections and testing voltages.
Important
The CA150 operates as a Class 0 PoE Powered Device (PD). As such, the CA150 requires the allocation of
15.4 Watts from the PoE switch or injector. Of the 15.4 Watts, the CA150 provides 680 mA at 12 volts –
approximately 8 Watts – to power connected peripheral devices such as readers, door strikes, PIR
sensors, etc.
Selection of a PoE switch must be based on the power demand of all of the loads connected to the switch.
The PD Class (0-4) for each device connected to the switch must be known and the sum of all loads, for a
conservative and reliable design, should not exceed 75% of the total available power. As loads are
disconnected and others connected, the total power consumption must be re-assessed. Keyscan
recommends the use of low port count PoE switches, maximum 8 ports, to minimize the impact of a switch
failure on the access control system and, that all PoE switches be powered using a UPS.
Program On-board Ethernet Module
If the CA150 is connected on a network (TCP/IP) using Keyscan’s standard polled communication, the unit’s
on-board Ethernet module has to be programmed with an IP address. This procedure is required so the CA150
can communicate with the PC/server that has Keyscan’s standard communication software.
The CA150 requires NETCOM Program Utility – version 6.0.18 or higher. Always use the latest NETCOM
Program Utility on the enclosed Keyscan CD when programming the on-board Ethernet module.
For a complete outline of requirements and procedures for programming the on-board Ethernet module for
standard communication, see page 92.
Configure the CA150 for Reverse Network
Communication – License Required
If the CA150 is connected on a network using Keyscan’s reverse network communication, the unit’s on-board
Ethernet module and the control board memory have to be programmed with IP addresses.
Generally, reverse network communication is used only in centrally managed access control applications.
A license must have been purchased – K-RN, V-RN or AUR-RNx – which includes encrypted reverse network
communication software.
If you have not purchased a license from Keyscan, do not configure the CA150 for reverse network
communication.
