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. DE C R Y P T A3 powered from the BATTERY INPUT

DECRYPTA

3

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 DECRYPTA3 gets 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.

DECRYPTA

3

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 DECRY PTA3 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

Insure that your circuit delivers less than 14V to DE CRYPTA3. 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 DE CRYPTA3 If you are using a battery, a battery charger and/or

equipment

Alternative power source 9-12V DC

DECRYPTA

3

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 DECRYP TA3 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 DECRYP TA3 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 DECR YPTA3 to a metallic water

pipe going to earth or to a rod deeply planted to earth.

Should several DECR YPTA3 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 DE CRYPTA3 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 DECR YPTA3

WARNINGS

- DECRYP TA3 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 DE CRYPTA3 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 :

and installation procedure.

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.

NOTE:

Every time you change the interval type or its settings, you should reconnect in order for the changes to be

applied.

- Using only one connection: DECRYPTA3 connected by Serial port only

Using both connections (USB and Serial)

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.

Listen-in function

Some alarm panels offer the option for the Central station operator to listen for sound in the premises where the alarm signal
originates.

Alarm panels supporting “Listen-in” keep the telephone line open after having sent a signal, to allow sound monitoring. The
telephone line will be closed by the Central station subject to operator action or receiver setup.

Listen-in criteria

DECRYPTA

is triggered into “Listen-in” mode for incoming events according to panel setup for specific formats.

SIA and Contact ID formats have specific codes for Listen-in. See Panel setup.

DTMF formats use the AEx signal where x can be 0 to F at the Installer’s choice.

3x1 and 4x2 formats have no standard codes for Listen-in. DECRYPTA3 allows self selection of Listen-in codes at
Setup time.

Receiver action upon reception of “Listen-in” trigger

Upon reception of event in the Listen-in category, DECRYPTA3 receiver maintains the telephone line open for a
period of up to 180 seconds or less then 180 seconds upon reception of any telephone tone from the keypad.

Operator must be warned by Monitoring software of account “listen-in” capability. Operator has a maximum of 180 seconds
from time of alarm reception to telephone pickup. Failure to pickup telephone in this delays will cause line hang-up by

DECRYPTA

3

receiver.

Once the line is seized by Central station local telephone, the hang-up action of DECRYPTA3 will have no effect.

To close communication with alarm signal site in the first 180 seconds when DECRYPTA3 is in action, operator
must press any key on the telephone keypad before hanging up. DECRYPTA3 will hang up telephone line before
180 seconds only upon reception of a tone from telephone keypad.

To close communication with alarm signal site after 180 seconds of event reception, simply hang-up the telephone. This is
because DECRYPTA3 is not in function anymore, its delay having expired.

1) The power required by the host and the total of all adapter cards installed within the host environment, together with any
auxiliary apparatus, shall not exceed the power specification of the host apparatus.

The power requirements for the DECRYPTA3 receiver are:

From External Battery (standby) 12V 1A

2) It is essential that, when other option cards are introduced which use or generate a hazardous voltage, the minimum
creepages and clearances specified in the table below are maintained. A hazardous voltage is one which exceeds 42.4V peak
a.c. or 60V d.c. If you have any doubt, seek advice from a competent engineer before installing other adapters into the host
equipment.

3) The equipment must be installed such that with the exception of the connections to the host, clearance and creepage
distances shown in the table below are maintained between the card and any other assemblies which use or generate a voltage
shown in the table below. The larger distance shown in brackets applies where the local environment within the host is subject
to conductive pollution or dry non-conductive pollution which could become conductive due to condensation. Failure to maintain
these minimum distances would invalidate the approval.

4) The analogue telecommunications interface is intended to be connected to telecommunication network voltage (TNV)
circuits which may carry dangerous voltages. The telephone cord(s) must be disconnected from the telecommunications system
until the card has been installed within a host which provides the necessary protection of the operator. If it is subsequently
desired to open the host equipment for any reason, the telephone cord(s) must be disconnected prior to effecting access to any
internal parts which may carry telecommunication network voltages.
