WARNINGS
-Removal of the power source during reception of an alarm signal may result in losing said signal.
-If 9-12VDC input is used as DECRYPTA3 sole source of power, events in receiver buffer will be not be lost when
power is removed and will be transmitted to PC when power is restored.
2. D E C R Y P T A 3 powered from the BATTERY INPUT
DECRYPTA3 can powered from a 12VDC battery only. Minimum requirements 12VDC 500 Ma. Severe damages to
the unit may occur if the battery delivers more than 14VDC.
Power led of front display will be blinking when the DECRYPTA3gets the power only from the Power Supply Input.
When both sources are used, the led will be ON steady.
WARNINGS:
-MCDI recommends choosing a high quality lead-acid battery or gel type. Most stores selling security equipment hold a variety of
power levels to choose from.
-If not charged, the battery will discharge. DECRYPTA3 does not provide battery supervision or charge to battery.
DECRYPTA3 is supplied with a Molex lock type connector. This connector has a red and black wire for connection to
battery.
-Do not use a battery supplying more than 14V DC. Significant heat dissipation will result and may damage unit. Do not use a
battery showing signs of tear, leak or corrosion.
-Never connect a faulty or drained battery to the DECRYPTA3.
Battery time
To calculated battery time:
HOURS OF CONTINUOUS BATTERY OPERATION = POWER IN A-H
Example with a fully charged new battery – 500mA drain from DECRYPTA3:
12V 600 mAh
1h12min
12V 700 mAh
1h25min
12V 70 Ah
140h
Always refer to battery manufacturer application notes on charging, using and discharging a battery.
Using 2 x 6Vbatteries (serial connection)
In using a serial connection, voltage of each power source will be added and delivered to DECRYPTA3.
Using 2 x 12V batteries (parallel connection)
Using a parallel connection of batteries, resulting current to DECRYPTA3 is the sum of current provided by each
source. Batteries should be matched to prevent heating among power components.
Battery charger
A battery along with a battery charger may be used . Using a supervision circuit is preferable. MCDI tested and recommends
Altronix PM212. and a 12V battery. A circuit like the Altronix PM212 will insure a constant tension (9-12V preferred), battery
charge and battery supervision

Operating guide for Alarm Receiver DECRYPTA3
MCDI Security Products Inc.. Internet: mcdi.com
7055 Jean-Bourdon Avenue, Montreal, QC, Canada H4K 1G7 Telephone: [phone] Fax: [phone]
Insure that your circuit delivers less than 14V to DECRYPTA3. Significant heat dissipation will result if using a power
source of more than 13.8V. This may damage the unit of reduce life expectancy of DECRYPTA3.
-Verify installation regularly.
-Consult a qualified Electrician prior to connecting DECRYPTA3 If you are using a battery, a battery charger and/or
equipment
Alternative power source 9-12V DC
DECRYPTA3 is shipped with a power adaptor. When another power supply is preferred for the 9-12V DC input, a
lower voltage should be preferred over a higher voltage to minimize heat dissipation in DECRYPTA3.
USB Hub
While testing several units, MCDI did not find a USB hub able to power TWO DECRYPTA3 units. You must power the
units by their 9-12V DC input if you plan to use a USB hub and use the USB hub only for the benefit of data concentration.
Ground post
As as safety for users and the DECRYPTA3 alarm receiver, DECRYPTA3 is provided with a ground post at
the back on the unit. A wire of AWG #14 should be used along with a lug connectors. Ground connection must be maintained
and verified regularly to insure ground to earth is always present.
Best practice in making a ground connection from DECRYPTA3 are to insure a non resistive connection to a known
and tested ground in a well built electrical installation or connect the ground lug of DECRYPTA3 to a metallic water
pipe going to earth or to a rod deeply planted to earth.
Should several DECRYPTA3 units be used it is preferable not to chain units by their ground lugs. A better practice is
to use a ground star technique according to Diagram.
Using a battery charger
MCDI tested and recommends a supervision circuit like Altronix PM212 (altronix.com). This circuit will take 16VAC wall
transformer (Alarm panel transformer) charge a 12V battery, insure supervision and will deliver power from battery when AC
feed is missing.
When using a battery charger, insure that the tension at DECRYPTA3 electrical entry is less than 14VDC. Applying
voltage of more than 14V DC may cause significant heat dissipation within unit. Damages may result and this may reduce life
expectancy of DECRYPTA3
WARNINGS
-DECRYPTA3 does not supervise battery.
-Verify electrical set-up regularly.
-Always use properly mounted and approved cables to connect DECRYPTA3
-Do not use an over charger battery or a battery dispensing more than 14VDC.
-Consult a qualified Electrician prior to connecting DECRYPTA3 If you are using a battery, a battery charger and/or
equipment not provided by MCDI Security Products Inc.
-Damages resulting from power surges of any kind of specifically excluded from DECRYPTA3 warranty.
USING ON-BOARD RELAY :
DECRYPTA3 is equipped with a relay to trigger an external device such as strobe light, dialer, siren upon reception of
an alarm signal.
Terminal posts are located at the back of the unit. Posts: 1 and 2 are Normally Open. Posts 2 and 3 are Normally Closed. Post
2 is the Common. Maximum rating : 110V DC or 125 V AC / 1A UL/CSA rating : 30V DC / 1A 110V DC or 125V AC /
.3 A.

Port:
Choose and connect to the port your receiver
device is attached to.
Interval:
Set interval at which a new log file will be
created. Possible choices are “Hourly”, “Daily”,
“Weekly” and “Monthly”. Consequently, each log
file will contain signals came within an hour, a
day, a week, or a month, respectively.
Day of month, day of week, hour, minute:
Set the exact time when a new log will be
created. The choices available depend on the interval chosen above. For example, if “Hourly” interval is selected,
and the minute is set to “10”, then a new log will be created at 13:10, 14:10, 15:10, 16:10 etc.

IMPORTANT: For flexibility of operations the signal received by the card can be acknowledged from either
USB or Serial connection. Therefore it is very important, when using both USB and serial connection, to
acknowledge signals ONLY from the main connection to the receiving software, and not from the
secondary one used for logging.
When connected in this fashion, Decrypta 3 will be seen by the PC as two COM ports. One, the serial
connection, is the physical COM port (ranged COM1 to COM4 usually depending on the number of
available serial ports). Another connection, through USB, is a ”virtual” COM port (can be in the range
COM5 to COM256). Both COM ports can be used to input signals to the PC, therefore one COM port can
be used to connect to PC receiver software, and the other port for logging or monitoring of signals.
