2.2 Installation instructions
2.2.1 Reader module installation
The MREM 77 reader module is already assembled in the KU 68-1901 or LK 80 installation box. The reader module can
of course also be installed in already installed installation boxes in masonry (KU 68-1901), the attachment is made with
one screw. Standard UTP cables can be used, which, after connecting the detachable terminal block, fits well into the
remaining place in the installation box. If the UTP cable does not meet the power requirements of the controlled lock or
opener, it is of course necessary to use cable cores with an adequate cross-section according to the installation
parameters. Shorten the cable so that you are able to snap the detachable terminal block, but at the same time so that the
coiled cabling fits into the designated space in the installation box.
2.2.2 RS 485 bus termination
It is advisable to terminate the RS 485 system bus so that there is no reflection on the line. If this reader module is the
last one on the bus, it allows the termination to be done by its own jumper - a jumper, which connects the already fitted
termination resistor. By default, the termination resistor is disconnected.
2.2.3 RS 485 idle states
This reader module does not allow to set idle states of the system bus. Set the idle states on converters APSLAN or CON
110.IP if needed.
2.2.4 Radio signal interferences
If a 125 kHz reader is used, it is necessary to take into account another 125 kHz reader in direct range - for example when
checking the door on both sides. In this case, the readers may interfere with each other. In the techfass system, it is
possible to use the so-called synchronization of reading between the reader and the reading module, which then do not
interfere with each other.
In general, if possible, we avoid mounting on metal substrates, it is recommended to perform a practical reading test or
contact support@techfass.cz.
Interference along the line, e.g. from an interfering power supply, can affect the reading distance or the reader's own
communication.

3Wiring diagram
3.1 Door control by RFID medium
The following figure shows the standard connection of the reader module. After a valid card or other medium is read by the
MREM 77 E reader module, this ID is evaluated directly by the MREM 77E module and, if valid, a relay is closed which
connects the power supply / control signal to the lock. The relay output can be configured in the control software to switch
standard, reverse or toggle, while setting the switching time.
Wiring diagram 1: Connection of one MREM 77 E reader module for control of one door. The module is also able to notify,
for example, a knocked out or door ajar on its AUX output.
3.2 Connection of multiple modules
It is possible to connect up to 32 modules to one line of the APS mini Plus system behind the APSLAN converter or
behind the cloud connector CON 110.IP. The lines can be further parallelized.
Wiring diagram 2: Up to 32 modules can be connected to one line of the APS mini Plus system and thus manage all doors
centrally. A REP 485 repeater can be used for star connection.

6Operating modes
There are two basic operating modes for the MREM 77 reader module.
▪Standard operating mode
▪External reader with wiegand output
6.1 Standard operating mode
Main operating mode. In this mode, the module acts as a controller for one door, reads RFID media and determines in its
memory whether or not the user should be authorized to enter and controls the lock output.
The module can be in online or offline standard operating mode. The function is identical in both modes, with the difference
that in the online mode, the module statuses are reported via the communication line (after changing the mode from offline
to online, the event archive is read from the module's memory). In both operating modes, the module can switch to
programming mode (after reading the programming card).
6.1.1 Offline mode
Offline, or autonomous / standalone mode. One module alone or more modules on the RS 485 bus, but without
connection to a PC. In this mode, events are stored in the module's internal memory, module authorizes users according
to the stored set access rights. Settings / configuration are performed by default using a PC or programming cards.
6.1.2 Online mode
In Online mode, the module or more modules on the line are connected to a PC running the relevant application such as
APS Hit or APS Administrator or the line is connected to the cloud using CON 110.IP and the administrator works in the
WebHit web application. In this case, each event is immediately written to the application.
6.1.3 Online authorization
The APS mini Plus system implements the option of Online authorization of access authorization. In such a use, the
connected PC decides on the validity of the read ID authorization. The reader must be MLO licensed to use it in this
authorization mode.
! Note: This feature is currently only available on desktop applications.
6.1.4 Secure lock control with WIO 22 module
The MREM 77 module itself contains a switching relay and there are connected wires to control the lock. In this simple
configuration, it is advisable to install the module in a safe zone, where we do not expect an attempt to overcome so that
someone will want to get to the cabling to control the lock. If we need the module to switch ‘‘ safely ‘‘, we connect the
WIO 22 module to its Wiegand output, we place WIO in a safe place, eg in a rack / cabinet or from the inside above the
door, from where it already controls the lock. The WIO module must first be paired with the MREM 77 reader module.

7Function
7.1 Functions of the reader module
▪Standard "Door open" function
▪Lock control
▪Door status monitoring
▪Exit button status monitoring
▪Activation of the alarm output / buzzer signaling when an alarm condition is indicated
The "Door open" function can be activated in three different ways
▪By reading a valid ID (card, key fob,…)
▪By pressing the exit button (depending on the configuration) - cannot be used during the alarm
▪Software, via communication line
7.2 Function ‘‘Door open‘‘
In the case of the standard lock control mode, after activating the "Door open" function, the release of the lock relay and
the buzzer are activated (unless disabled by configuration). This state lasts until the door is opened, but no longer than
the time set by the "Lock activation time" parameter. Then the lock output is deactivated and the standard function is
terminated.
In the case of the toggle lock control mode, after activating the "Door open" function, the relay output toggles and the
buzzer is activated (if it is not disabled by the configuration). The acoustic signaling lasts as set. The relay output remains
unchanged until the next activation of the "Door open" function.
In the case of the pulse lock control mode, after activating the "Door open" function, the relay output is activated for the
time given by the parameter Pulse width (ms).
In the case of the standard lock control mode, reading a valid card during lock activation will cause a new lock timing.
Online authorization
If the reader module reads the ID card during the "Door open" function via the communication line (in online mode) and if
the read ID is not valid, it is signaled by an acoustic signal "invalid ID" regardless of the configuration of the acoustic lock
release message.
7.3 Permanent lock release based on valid time schedule
When this function is set, the lock is permanently released during the validity of the respective schedule, the reading of a
valid ID is reported via the communication line (in online mode). When the lock is permanently released, the alarm state
of the forced door does not occur.
The setting of the permanent release of the lock according to the time schedule and the toggle lock control mode are
mutually exclusive.
7.4 Function of ID with flag
It is possible to set a flag for each ID, which will cause an alarm ‘‘ Alarm - ID with the flag ‘‘ when reading the appropriate
ID (and will activate the alarm output for a defined time).
7.5 ID expiration
It is possible to set a date for each ID at which the ID expires and will no longer be valid. The expiration is evaluated every
time the data in the RTC module changes and when new access rights are loaded.
! Note: This feature is currently only available on desktop applications.

www.techfass.com RFID reader module MREM 77 17
7.6 Antipassback function (APB)
Antipassback can be implemented in two ways:
▪Time - the user must not use the ID medium repeatedly for a defined time
▪Zone - the user must not repeatedly enter the area in which he is present
The antipassback function is used only for users who have defined access according to a schedule. The function does
not apply to users with permanently valid access.
Zone and time antipassback IDs can be reset by re-inserting the IDs using the programming cards. After reloading the
access rights by the program, the antipassback flags are reset for all IDs.
The zone and time antipassback flag is written according to the configuration either immediately after reading the ID, or
only after opening the relevant door (opening the relevant door contact).
7.6.1 Time antipassback
The time antipassback is defined by setting the duration (in minutes), which is set for the given ID when passing at the
given address. The next time the ID is identified at the relevant module address during the timer run for the given ID, a
time APB alarm is triggered. The following parameters affect the time antipassback function:
▪Default value of the APB timer - the time for which the APB timer alarm is triggered at the next ID identification,
the timer is set for the given ID when passing at the given address.
▪Enable door opening after time APB alarm - if the function is enabled, the Door opening function is started in
case of time APB alarm.
7.6.2 Zone antipassback
Zone antipassback is defined by enabling / disabling this feature. The zone antipassback flag is set for the user after
passing. Upon further identification, a Zone antipassback alarm is triggered in the case of a flag set for the given ID. The
following parameters affect the zone antipassback function:
▪Enabled - global enable / disable of the zone APB flag setting function.
▪Enable offline mode - if not set, the module works in offline mode as if the zone antipassback function was not
implemented at all.
▪Enable door opening after APB alarm - if the function is enabled, the Door opening function is started in case of
a zone APB alarm.
7.7 Disabling the reader module
Disabling of the reader module function can be configured on the second input or on the third I / O port of the module.
The function activation logic on each port is configurable. The function is activated if at least one of the ports is active and
set as disable.
The module in the disabled state exhibits the following behavior:
▪Users with set time schedule cannot trigger the door open function if it is disabled
▪Disable does not apply to the users with permanently valid access (no time schedule)
▪The remote door opening function cannot be performed
▪Remote door opening with ID is blocked for users with time schedule.
Changes in the status of the disable function and the blocked action are recorded in the event archive.
This function is useful for example in combination with intruder alarm system.
7.8 Alerts and their signaling
The following alert conditions may occur during the reader module operation:
1) Tamper.
2) Forced door.
3) Door ajar.
4) Antipassback alert (time, zone).
5) Alarm ID with flag.
To deactivate any alert, please set its value to “0”.
Alerts are reported as follows:
▪In software, by system bus (alerts 1, 2, 3, 4, 5)
▪Acoustic (alerts 1, 2, 3, 4)
▪Activating the alert output (alerts 1, 2, 3, 5)

www.techfass.com RFID reader module MREM 77 18
The alarm message via the communication line assumes an online connected PC with the appropriate software suitable
for online operation (APS Administrator).
The audible alert message is twofold:
▪Continuous tone (distortion)
▪Intermittent tone (knocked out and long open door, APB alarm)
The acoustic message ends either after the set time (see configuration table)
or after reading a valid ID on the relevant module.
When one of the relevant used alarm conditions occurs (signaling time
alarm must be greater than 0) the alarm output will be activated. On this output is
it is possible to connect the alarm device directly or to further process its signal.
The triggering of the alarm is controlled by a logical connection or between individual types
alarms.
The alarm condition is terminated by restoring all idle conditions (closing the door, fitting the cover, etc.).
7.8.1 Tamper
The MREM 77 E / F reader module is not equipped with a Tamper sensor to detect that the lid is open. This is due to the
variability of the covers that can be used with it. The module itself is ready for the connection of the tamper, for possible
installation it is necessary to share the intended cover and agree in advance by contacting suppo[email protected].
The "Violation" alarm state is generated by activating the Tamper signal by opening the cover of the reader module, or by
changing the state of the 2nd or 3rd input in the tamper configuration.
The Violation alarm state is evaluated only after the first idling state after switching on the reader module, if it is not
installed, there is no need to configure the module in any way.
7.8.2 Forced door
The "Forced door" status occurs when the IN1 input of the module is opened without first activating the "Door open"
function. The only exception is the exit button / handle contact signal activation from the inner side of the door.
7.8.3 Door ajar
The "Dopr ajar" status is activated by opening the door for a longer time than allowed (set), see the configuration table.
7.8.4 Antipassback alarm
Antipassback alarm is generated when a valid card is read at the time of blocking the user by Time APB,
or when the user is blocked by a Zone APB.
7.8.5 Alarm ID with flag
Alarm ID with a flag occurs when a card (ID) with flag is read.
7.8.6 Reading ID in time of alert
Reading a valid ID has no effect on the alarm conditions themselves. It is terminated with a valid ID
only an audible alarm, followed by the "door open" function. Reading an invalid ID only interrupts the audible alarm for the
duration of the "invalid ID" signaling.

7.9 Simplified access rights model
The access rights model includes schedules and a holiday table. The block diagram for access evaluation is shown in the
following figure.
7.10Offline setting (programming) mode
For small simple autonomous installations, users can be set up using programming cards. The module enters the
programming mode by reading one of the pair of programming cards ("+" and "-" cards). It does not enter the
programming mode while waiting for the card confirming the address setting (for modules with address setting via the
communication line). The behavior of the modules in the programming mode is evident from Fig. 5 a-d.
When inserting cards using programming cards, it is not possible to work with time schedules, so the cards are still valid.
7.10.1 Inserting cards (ID codes) into the memory
Follow these steps for inserting cards into the reader module’s memory:
Step 1
Step 2
Step 3
Read the programming card
for inserting: the reader goes
into programming mode.
One by one, read the cards
which are to be granted
access.
About 15 seconds after
inserting the last card the
reader module goes back
into standard operating
mode.

7.10.3 Deleting cards „above or below“
If a user loses his ID medium, it is usually impossible to delete the ID from the memory with the procedure described in
the previous chapter, since the medium is no longer available (with an exception of entering the code at the keypad).
Following procedure can be used for deleting such ID. The procedure requires using an ID medium, which was inserted
right before or right after the ID medium, which should be deleted.
Step 1
Step 2
Step 3
Read the programming card
for inserting: the reader goes
into programming mode,
which is indicated by slow
flashing of yellow LED.
Read the programming card
for inserting 5 times in a row;
the reader will go into
Deleting cards “above or
below” mode indicated by fast
flashing of yellow LED.
Read a card, which is located
in the module’s memory right
before or right after the card
you wish to delete. After this
step the module quickly
flashes with yellow LED
Step 4 - A
Step 4 - B
Step 5
For deleting an ID located
right before the ID used in
precious step, read the
programming card for
deleting.
For deleting an ID located
right after the ID used in
precious step, read the
programming card for
inserting.
The reader module goes back
into standard operating
mode.
