INTRODUCTION
The Presco™ Digital Door Access Decoder utilises the
latest microprocessor technology to operate most electric
door locking devices on the market. The decoder together
with an encoder (Presco™ keypad (PRE or PSE) or a
Presco™ Interface Module (PIM) with a Clock & Data
(magnetic card format) or Wiegand output reader) offers
access control to restricted areas.
FEATURES
Split system for maximum security (Encoder & Decoder).
Door Forced Open detection.
Door Open Too Long (DOTL) function.
EGRESS function.
Automatic door relock function.
Easy on site programming using any Presco™ keypad.
600 client programmable users.
Heavy Duty 5 Amp. relay contacts for lock control.
Can operate Fail Safe or Fail Secure electronic locking
mechanisms.
1 Amp Normally Open DOTL Alarm relay output.
10 year non volatile EEPROM memory.
36 month (3 year) manufacturer’s warranty.
Designed and manufactured in Australia.

CHANGES FROM SERIES 2
1. The PAC1 now supports 600 user codes.
2. Egress input can now be programmed as edge triggered
(momentary only) so that keeping the Egress input
triggered will not keep the door open permanently.
3. User code programming has been simplified (refer to the
supplied User Code Programming Manual).
4. Bulk adding of users is now supported.
5. Can be set to Series 2 compatible mode for use with
existing PACDL installations.
6. Two Codes Mode is now called High Security Mode.

TERMINAL DESCRIPTIONS
GND Negative input (or ground) from the power supply.
AC-DC A.C. 16 - 24 Volt or D.C. 12 - 24 Volt positive input
from the power supply.
DTA Data line to encoder (white wire on keypads).
LED Output to drive a LED to indicate door unlocked.
ELC (Electric Latch Control) 5 Amp relay output. The
ELC relay is used to control the door
locking/release mechanism. The relay can be
programmed as either Normally Open for fail
secure applications (power applied to open door)
or Normally Closed for fail safe applications
(power applied to lock door).
DOOR This input requires a normally closed switch
connected to ground, typically a reed switch
attached to the door. The DOOR input is used by
the PAC1 to monitor when the door is physically
open (not unlocked). In order to use this input it
must first be enabled (via memory 84, refer to
page 15) and a normally closed (when the door is
closed) door switch (or monitored lock contacts)
must be connected between DOOR and GND.
The DOOR input is used to detect when the door
has been opened for use by the door forced open,
Door Open Too Long and automatic relock
functions.
DOTL (Door Open Too Long) 1 Amp Normally Open
relay output, operates when a DOTL or Door
Forced Open alarm condition occurs.
4
EGRS The EGRESS input can take either a normally
open or normally closed switch between EGRESS
and GND. When this input is activated the ELC
relay will come on and remain on for the time that
the EGRESS input is on. Once the EGRESS
input is released the timing set for ELC will begin.
The other selected features of the PAC1 (DOTL,
Door Forced Open & Automatic Relock) will also
become active at this time. Therefore the
EGRESS input can be used to hold the door open
indefinitely with the use of a toggle switch, or with
the use of a momentary type switch it can be used
to release the door for a set time in exactly the
same way that a momentary user code does.
DLOG Data input/output for connection to an optional
PELSA1 or PEL1 event logger or a PACDL when
in Series 2 Compatible mode.

PROGRAMMABLE FEATURES DESCRIPTION
Automatic Relock Function
When the DOOR input is used then the Automatic Relock
function can be used. This feature turns the ELC relay off 1
second after the door is opened (not unlocked) when a
momentary code or the EGRESS input has been used (no
matter how long the time for the ELC relay operation has
been set for in memory 83). The purpose of this feature is
to stop people following someone through the door by
ensuring that the door locks once it closes.
Door Open Too Long
The DOTL timer is used to warn if the door has been held
open for too long after a valid access (either via a code or
EGRESS). When the door has been opened a countdown
timer is started (the time set in memory 85, refer to page
16). If the door has not closed again by the time this
counter expires then the DOTL output will activate (contacts
will close) and will remain active until the door is closed.
Note that if a value of 0 has been set for the DOTL time
then the door is allowed to remain open indefinitely.
Door Forced Open
A door forced open condition is defined by the situation
where the door has been opened but a code or EGRESS
has not been used to gain access. When this condition
occurs the DOTL output will activate (contacts will close)
and will remain active for 30 seconds or until the door is
closed again (whichever is the longer time). Note that the
Door Forced Open feature must be disabled (set in memory
86, refer to page 16) if a free (unmonitored) inside door
handle is used instead of an EGRESS button. When this
feature is disabled the Door Open Too Long timer will be
started when the PAC1 detects the door has been opened.
6
One Minute Lockout
To increase security the PAC1 can be set to lock out all
codes for a period of 1 minute after 5 incorrect codes have
been tried (set in memory 87, refer to page 16). Note that
this feature should not be enabled if access must be
guaranteed in an emergency situation.
High Security Mode
The PAC1 can be set up to operate in one of the four
modes described below.
Normal Mode (High Security Mode Disable)
Any one of the programmed user codes will operate the
ELC relay.
Any Two User Codes
Any two of the programmed user codes must be used
together to operate the ELC relay.
Code 000 or 001 and any other user code
The user code stored in memory 000 or 001 used
together with any other valid user code will operate the
ELC relay.
Sequential Memory User Codes
Two user codes in sequential memory locations must be
used together to operate the ELC relay. The paired
code locations start with an even number, e.g. 000 &
001, 056 & 057, 138 & 139, etc.
IMPORTANT NOTE: When the PAC1 is set up to use any
of the high security modes above, the ELC relay will only
operate in Momentary (timed) Mode even if the codes are
programmed as Toggle codes.

INSTALLATION
Read all instructions carefully before installing,
programming and using the system. It is vital that all power
be disconnected during wiring.
To maximise security ensure that the decoder and encoder
components are separated and that the decoder is
inaccessible to persons outside the restricted area. The
decoder should be installed indoors and in a dry secure
place. The maximum distance of separation between the
decoder and encoder is 1 kilometre.
The wiring diagrams for installation are on the following
pages.
