Introduction
This document is intended for experienced engineers who are
familiar with PAC products and health and safety considerations.
Additional information on software installation and operation is
given in the documentation and help files provided with the
administration software.
All similar controllers on the system should have the
same firmware version number.
A firmware download to the new controller may be required, see
the help file for further details.
Tamper and Override Terminal (NC)
Before powering up, use a short piece of cable to link:
tamper (TAMP) and 0V terminals.
l
override (OVERRIDE) and 0V terminals.
l
Override can be configured for EOL operation if required.
RS-485 Connection
When shielded cables are used, connect the shield on one
controller to the earth terminal labelled "SHIELD".
Only the first and last controllers in the chain, must
have the RS-485 dipswitch set to "IN".

Lock EMF Suppression
All locks must be fitted with a means of suppressing back EMF
('spikes'), which are generated by most electric releases, especially
magnetic locks.
All readers and controllers supplied by PAC are supplied with a
Metal Oxide Varistor (MOV).
For currents >1A use the large MOV supplied with the controller.
For currents <1A use the small MOV supplied with the reader.
The MOV will prevent the controller from suffering long term
damage.
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 automatically be reset
when the overload has been removed; both lock outputs are
independent.
