2.3 Environmental Conditions
Operating and storage temperature Absolute maximum: -20 °C … +60 °C
Recommended 1): +10 °C…+30 °C
Operating and storage humidity Maximum: 0% … 93% r.h., non-condensing
Recommended: < 60% r.h.
Shelf life (in absolute darkness) 36 months after delivery in transport mode 2
Note 1: Recommended for maximum life of energy storage capacitor. The following effects will lead to
shorter dark time operation:
a) Long time exposure of the unit to temperatures higher 30°C will gradually degrade the en-
ergy storage performance over lifetime.
b) Lower temperatures than 10°C will noticeable reduce capacity of energy store, but tempo-
rarily only.
Note 2: Recharge energy storage after 36 months in total darkness. Deep discharge of the energy
storage leads to degradation of performance. Therefore, the device must be put into operation after 36
months in transport mode.

3FUNCTIONAL DESCRIPTION
3.1 Block Diagram
A change of the reed contact status or pushing the LRN button will wake the transmitter unit
to send a radio telegram immediately (reed contact position, LRN push button status, unique
32-bit sensor ID, checksum). In addition a redundant retransmission signal is sent to an-
nounce the contact status even in case of no input signal changes. This signal is transmitted
every 20-30 min, affected at random. The transmit indicator LED flashes briefly at every
radio transmission. Between the wake-up phases the device is in sleep mode for minimum
power consumption.
3.2 Teach-in to Receiver Unit
Push the button behind the hole in the side wall to trigger a teach-in telegram. You will see
a LED shining at the housing side as telegram indicator (pay attention to a sufficiently dark
environment).

When pressing the LRN key, the module sends a teach-in telegram to a suited receiver ac-
cording to the currently selected communication mode (see chapter 3.3, 4BS teach-in tele-
gram for standard mode, secure teach-in telegram for Secure Mode). The teach-in telegram
identifies the device manufacturer and the function and type of the device via the EEP used.
For EASYFIT devices, EnOcean is set as manufacturer with ID 0x00B.
3.3 Commissioning and Mode Change
The module is shipped in Transport Mode (Mode 3) to switch off the energy store for long
term shelf storage and air cargo. The mode can be changed by pressing the learn button.
Please note that the modes have been changed with Stepcode DE (and later). Make sure that
the solar cell will get enough light for mode change and/or learn telegram.
◼Change from Transport Mode to Standard Mode:
After pressing learn button 1x short (around 1s) the radio module will enter Standard
Mode (Mode 1). A standard learn telegram will be sent and the LED will flash 2x.
◼Change from Standard Mode to Secure Mode:
After pressing learn button 2x long (2x around 5s, pause <1s) the radio module will
enter Secure Mode (Mode 2). A secure learn telegram will be sent and the LED will
flash 2x.
◼Change from Secure or Standard Mode to Transport Mode:
After pressing learn button 1x long (around 5s) the radio module will enter Transport
Mode (Mode 3). A signal telegram will be sent and the LED will flash 3x.
The following diagram illustrates all implemented mode transitions:

Figure: Mode Transitions
The following pushbutton timing is implemented:
•Short press: around 1s (firmware 0.1 –3.0 s)
•Long press: around 5s (firmware 3 –7 s)
•2x long press with very short pause of max. 1 s between
Before changing the operating mode please make sure to clear the device from all
receivers which have been taught to work with this device before. Otherwise the
receiver will ignore the telegrams and the application will not work.
The flag for actual mode itself is stored in non-volatile memory. After power down
reset the previous selected mode is active. The mode change is limited to 50 times.
In normal application scenario only very few are required.
3.4 Radio Telegram Format, EEP
3.4.1 Standard Mode
EMCSx transmits a radio telegram according to EnOcean Equipment Profile EEP D5-00-01 as
defined in the EEP EnOcean Equipment Profiles specification:
www.enocean-alliance.org/eep/

USER MANUAL
EMCSA / EMCSU / EMCSJ
ENOCEAN MAGNET CONTACT SENSOR
© 2022 EnOcean | www.enocean.com F-710-017, V1.0 EMCSx User Manual | April 2022 | Page 15/31
3.4.2 Secure Mode and Secure Telegram (Stepcode DE and later)
In Secure Mode the payload content of the telegram is protected with advanced security
features. Normal operation telegram payload and also teach-in telegram payload both are
protected in the same way. The security features used are defined by the Security Level
Format (SLF). This parameter is set by default to following values:
◼24-bit RLC which starts from 0 at production
◼RLC sent explicitly
◼3-byte CMAC
◼VAES encryption
The security features are added to the communication by encapsulating the payload and
teach-in telegram payload into a secured telegram. The payload itself is not changed and
corresponds to the standard mode payload like defined by EEP D5-00-01. Please refer to the
EnOcean Security Specification for details:
http://www.enocean.com/en/security-specification/
3.4.3 Secure Learn Telegram
In Standard Mode an 1BS teach-in telegram is transmitted by pressing the LRN button. To
process secured communication on a receiver the EMCSx has to send a security teach-in
telegram to the receiver and so inform him about the used security profile, AES key and
initial RLC counter. The security teach-in has to take place before any other communication
can be executed (profile teach-in included). Press the LRN button to trigger the transmission
of the teach-in telegram. The security teach-in and then the profile teach-in are transmitted.
The profile teach-in telegram is already protected by advanced security features. The process
of sending security teach-in telegram and profile teach-in telegram is triggered by pressing
the LRN button in secure mode, the behaviour of the LRN button is following:
1. Button is pressed
2. Security teach-in is send.
3. Profile teach-in is send.
For more information on the structure of the teach-in telegram please refer to chapter 4.2 of
the EnOcean Security Specification: www.enocean.com/security-specification
3.5 Radio Telegram Timing
The setup of the EMCSx transmission timing reliably avoids possible collisions with data pack-
ages of other EnOcean transmitters as well as disturbances from the environment.
3.5.1 Standard Mode Transmission Timing
In Standard Mode with each transmission cycle, 3 identical sub-telegrams are transmitted
within 40 ms. Transmission of a sub-telegram lasts approximately 0.9 ms. The delay between
the three transmission bursts is affected at random.

Figure: Transmission timing in Standard Mode
3.5.2 Secure Mode Transmission Timing
In Secure Mode the transmission cycle is reduced to 2 identical sub-telegrams that are trans-
mitted within 20 ms. This compensates the additional energy requirement of enhanced se-
curity computing and additional payload. The transmission of a sub-telegram lasts approxi-
mately 1.2 ms.
3.6 Storing the Rolling Code Counter (RLC)
In Secure Mode the RLC counter needs to be stored in a non-volatile memory. For security
reasons the RLC counter is incremented by every transmitted telegram. Together with the
CMAC the RLC ensures that messages cannot be reproduced or forged. The RLC is stored in
the chip flash memory. To improve the endurance of the flash memory and also the energy
budget not every increment is saved to the non-volatile flash memory. During deep sleep the
RLC is stored in RAM0 memory.
3.7 Energy Consumption / Battery Lifetime
The diagram in chapter 3.4 illustrates a complete cycle in standard mode which starts with
controller active phase (setup, measurement etc.) immediately followed by a telegram trans-
mit. After short sleep phase the controller will get active two times and send two telegrams.

◼10 reed contact changes per day (e.g. 5x window open/close)
◼Average leak current of STM 3xy at 25°C: 0.5 uA
◼Wake-up cycle 20 - 25 min (average 1.500 s) for status telegram
◼8 h light per day (24 h) light @ 200 lux and 25°C
3.7.2 Example calculation of the energy consumption
◼Current consumption (depending on amount of wake-ups due to reed contact
change):
•Current consumption for status telegrams and sleep:
100 uAs / 1,500 s + 0.5 uA = 0.57 uA
•Power consumption for 10 reed contact changes incl. additional transmits per
day: 100 uAs / (60 x 60 x 24 s) = 1.2 nA = 0.0012 uA)
•Average current consumption: 0.57 uA
◼Average solar power harvested: 5uA / (8 h / 24 h) = 1.67 uA
◼Time to fully charge energy storage (2.4 to 3.0 V) at stable temperature:
0.7 mAh / (1.67 uA –0.57 uA) = 636 h = 27 days
◼Average operation time in darkness when fully charged (3.0 V to 2.4 V):
0.7 mAh / 0.57 uA = 1,228 h = 51 day
Remarks:
◼Calculation examples and values have tolerances of about +/- 20%.
◼Energy storage performance, power consumption and solar cell performance varies
over temperature.
◼Energy storage performance degrades over lifetime, especially if energy storage is
long time exposed to very high temperatures. High temperatures will accelerate ag-
ing, each 10 K increase from 25°C will half expected life time. Very low temperature
will temporary reduce capacity of energy store and this leads to considerable shorter
dark time operation.
◼Short wake-up cycles (e.g. 1 s) and transmit intervals (e.g. 1 s) significantly reduce
energy storage performance, for this use case an external power supply is recom-
mended.
3.7.3 Consumption in secure mode
Enhanced security mode requires more energy due to encryption algorithm computing time
and extended telegram length because of CMAC. This added consumption is compensated by
reducing the sub-telegram count to 2.
3.7.4 Battery lifetime calculation
Battery lifetime calculation for operation in total darkness (no support by solar cell):
◼Current consumption for status telegrams and sleep: 0.57 uA (= 100 uAs / 1,500 s +
0.5 uA, see 3.6.2)
◼Average current consumption for 100 red contact changes per day = 12.0 nA (= 1.2
nA x 10, according to 3.6.2)
◼CR1225: 48mAh according to data sheet. Assume you can discharge by 90%, 43mAh
are left for use
◼By that CR1225 life time = 43mAh / (0.57 + 0.012) uA = 75438h = 8.6 a
◼You can assume CR1225 self-discharge reduces this number by additional 10%
◼Results in lifetime of EMCSx powered by battery only: 7.8 years

This calculation assumes constant room temperature (22°C). In order to take dynamic effects
into account, the operating characteristics overview in chapter 2.2 indicate at least 5 years.
Please also note, this is an energy balance calculation, early failure of batteries is not con-
sidered. In practical operation, at least some light will be available that enlarges this calcu-
lated lifetime in addition.

4APPLICATION INFORMATION
4.1 General Installation Instructions
The reed contact unit and the magnet are both easily mountable at windows or doorframes
made of aluminum, plastic or wood using the included adhesive pads. Mounting position of
the reed contact unit is horizontal, vertically or even tilted. The reed contact housing offers
protection against splashing water drops. Mounting the reed contact unit on metal surfaces
or aluminum window frames will reduce the radio transmission range. This physical effect is
strongest in extension of the metal surface. So if the unit is mounted on a metal surface
please note that a radio receiver unit should NOT be mounted at the same window front side.
Further important installation notes please find in the Installation Instructions pro-
vided together with the unit.
4.2 Magnet Positioning
The very flat magnet can be very easily mounted onto a smooth surface using the preinstalled
adhesive tape. The magnet has to be positioned by facing the housing near to the middle of
the reed contact marking as follows:

Magnet in Righted Position
(Typical for window mounting)
The magnet can be positioned in vertical or in horizontal position to the reed contact housing.
The distance between housing and magnet should be less than 4 mm.
