PAC 512/512 IP Guia De Inicio Rapido página 4

Introduction
This document is intended for experienced
engineers who are familiar with PAC products and
health and safety considerations. An installation
diagram is given. Further information on hardware
installation is given in the installation guide
provided on CD. Information on software
installation and operation is given in
documentation and help files provided with the
administration software.
Note
It is recommended that all similar controllers on
the system have the same firmware version
number. Therefore, a firmware download to the
new controller may be required, see the help file
for details.
Tamper and Override Terminal
Because tamper and override are normally closed
switches, use a short piece of cable to link the
TAMP and 0V terminals and OVRD and 0V
terminals before powering up. OVRD can be
configured for EOL operation if required.
RS-485
If shielded cables are used, connect the shield on
one controller to 'Earth'. The first and last
controllers in the chain (and no others) must have
the RS-485 termination jumper linked (set to IN).
The red RS-485 LED indicates when the
controller is transmitting data and green RS-485
LED indicates when there is data on the network.
Lock Suppression
All locks must be fitted with a means of
suppressing back EMF ('spikes') generated by
most electric releases, especially magnetic locks.
All readers and controllers supplied by PAC are
supplied with a Metal Oxide Varistor (MOV). If
large currents are used (i.e. >1A) use the large
MOV supplied with the controller. If small currents
are used (i.e. <1A) use the small MOV supplied
with the reader. The MOV will prevent long term
damage being done to the controller. Whenever
possible this device should be fitted across the
lock terminals. If for any reason, the lock terminals
are inaccessible, the MOV may be fitted across
the lock output. The lock relays are protected by a
3A circuit breaker in line with the RELAY COM
connection. These will be automatically reset
when overload has been removed; both lock
outputs are independent.
