Normal, Secure, & Master Users

AC-Q74 Installation and Programming Manual 15

5. Normal, Secure, & Master Users

The AC-Q74 accepts up to 500 users and provides entry via the use of
proximity cards and/or PIN codes. Each user is provided with two code
memory slots, Memory Slot 1 (Primary code) and Memory Slot 2
(Secondary code). The two memory slots can be programmed as
Proximity Cards, PIN codes, or a combination of both Proximity Cards
and PIN codes.

The way in which the two memory slots are programmed determines
a user’s access level and also determines the way in which the AC­Q74 grants access in its three modes of operation.

There are three user levels:

 Normal User

A Normal User only has a Primary code and is only granted access

when the AC-Q74 is in Normal or Bypass Mode.

 Secure User

A Secure User must have a Primary and Secondary code

programmed; the two codes must not be the same. The Secure

User can gain access when the AC-Q74 is in any of its three

modes of operation. In Normal Mode the Secure User must use

their Primary code to gain entry. In Secure Mode, the Secure User

must present both their Primary and Secondary codes in order to

gain entry.

 Master User

A Master User must have both Primary and Secondary codes

programmed with the same Proximity Card or PIN code. The

Master User can gain access during any mode of operation by

presenting their Proximity Card or PIN code to the controller. (The

Master User is convenient but is less secure than a Secure User.)

Modes of Operation

16 AC-Q74 Installation and Programming Manual

6. Modes of Operation

The AC-Q74 has three modes of operation:

 Normal Mode
 Bypass Mode
 Secure Mode

6.1 Normal Mode

The Mode LED is green.

Normal mode is the default mode. In Normal mode, the door is
locked until a Primary code is presented to the controller. Special
codes such as Lock Strike Code 1 and Lock Strike Code 2 are active
in Normal mode.

See Sections 11.3 and 11.4 for more information on the Lock Strike
codes.

6.2 Bypass Mode

The Mode LED is orange.

In Bypass mode, access to the premises is dependent on whether the
controller's Lock Strike Relay is programmed for Fail Safe Operation or
Fail Secure Operation.

When the Lock Strike is programmed for Fail Secure Operation, the
door is locked until the doorbell button is pressed.

When the Lock Strike is programmed for Fail Safe Operation, the door
is constantly unlocked.

Request to Exit (REX) Function

20 AC-Q74 Installation and Programming Manual

8. Request to Exit (REX) Function

The REX button is connected to the Power Supply Unit (PC-25T). The
REX button must be located inside the premises to be secured and is
used to open the door without the use of a proximity card or PIN
code. It is usually located in a convenient location, such as inside the
door or at a receptionist's desk. The function of the REX button
depends on whether the Lock Strike Relay is programmed for Fail Safe
Operation or Fail Secure Operation.

 Fail Secure Operation: From the moment the REX button is

pressed, the door is unlocked until the Lock Strike Release Time

has passed. After this time, the door is locked even if the REX

button is not released.

 Fail Safe Operation: From the moment the REX button is

pressed, the door is unlocked until the REX button is released,

plus the Lock Strike Release Time. In this case, the Lock Strike

Relay only begins its count down once the REX button is released.

Case and Back Tamper

AC-Q74 Installation and Programming Manual 21

9. Case and Back Tamper

If the case of the controller is opened or the controller is removed
from the wall, a tamper event is triggered and a coded tamper signal
is sent to the PC-25T Power Supply, or other compatible device,
which activates the siren.

Clearing a tamper event is done by entering a valid Employee or Lock
Strike code that opens the Lock Strike Output in the current mode of
operation. For example, while in Secure mode, using the Lock Strike
codes to clear tamper event does not work because the Strike codes
does not work in Secure mode. However, applying a Master code or
Secure code clears the tamper event in Secure mode.

PC-25T Power Supply Unit

22 AC-Q74 Installation and Programming Manual

10. PC-25T Power Supply Unit

The PC-25T is designed for use with Rosslare's secured series, stand
alone access control units, including AC-Q74. It is designed to operate
indoors and installed within the premises to be secured.

The AC-Q74 must be used with PC-25T, which provides its Lock Strike
output, Request to Exit (REX) Input and Bell Function.

Both units communicate through a proprietary Rosslare protocol,
which provides a secure link between the controller and the power
supply unit. This in turn activates the door unlocking.

The PC-25T also functions as the power supply for the AC-Q74.

Programming the AC-Q74

AC-Q74 Installation and Programming Manual 23

11. Programming the AC-Q74

Programming the AC-Q74 is done solely via the unit's keypad driven
Programming Menu System. To reach the Programming Menu System

11.9 Enrolling Primary & Secondary Codes

11.9.1 Primary Codes

 Primary codes can only be enrolled to an empty User Slot – a slot

where there is no existing Primary code.

 Primary codes must be unique – one user’s Primary code may not

be the same as another user’s Primary code.

 Primary codes cannot be the same as any system codes, such as

the Normal/Secure code or Lock Strike code.

 Users who hold a Primary code can gain entry only during Normal

mode.

11.9.2 Secondary Codes

 Secondary codes can only be enrolled to a User Slot that already

has a Primary code enrolled but no Secondary code.

 Secondary codes do not have to be unique – multiple users can

all hold the same Secondary code.

 Secondary codes cannot be the same as any system codes, such

as the Normal/Secure code or Lock Strike codes.

 Users who hold Secondary codes can gain entry in any Mode of

Operation.

11.9.3 Enrolling Primary and Secondary Codes

There are two methods to enroll Primary and Secondary codes, the
Standard Method and the Code Search Method.

 The Standard Method is mainly used when the User Slot number

for the user you wish to program is known. You can program

Power Supply Installation Instructions

12. Power Supply Installation

Instructions

The power supply installation instructions are relevant for the
following models:

 PS-25T
 PS-A25T
 PS-C25T
 PS-C25TU

12.1 Introduction and Key Features

The PC-25T Power Supply is designed for use with all Rosslare secured
series stand-alone access control units. The PC-25T contains two
power supplies. One power supply is for the lock strike, the other is
for the access control unit (ACU).

The lock strike is attached directly to the power supply. This design
isolates the lock from the ACU securing the functionality of lock even
if the ACU is tampered with. When a valid code is entered at the
ACU, the ACU communicates to the power supply using a Rosslare
proprietary protocol sending a command to activate the lock.

Similarly, the Release to Exit (REX) button is attached directly to the
power supply. When the REX is pushed, the power supply
communicates the REX request to the ACU and then the ACU
communicates back to the power supply to activate the lock strike.

If the data line between the ACU and the power supply is cut, the
system immediately detects that the data line has been tampered
with.

Power Supply Installation Instructions

38 AC-Q74 Installation and Programming Manual

A sealed lead acid battery charger is built-in to provide back-up power
for the ACU and the Lock Strike. The PC-25T can also power an
external speaker that is controlled by the ACU to annunciate Bell,
Chime and Siren tones.

The PC-25T is also available in two steel enclosures. For more details
