System Operation Summary: In this present day and time, Cell/Mobile-Phones have become a major communication tool that eases

our daily life as we do way more with this tool these days. Talk, surf the internet, check emails,

send/receive text messages and many more. The question of receiving visitor’s call on your land-line or

mobile-phone is not the key issue, the issues are: Receiving those calls on the go real-time, Allow/Reject

access with a single key on the phone to unlock door, and no dedicated land-line phone required.

Designed with Mobile Network Platform in mind which technically means reliability. It’s quiet certain

that it cost way less for cell-phone service at this present time compare to cost of maintaining land-line

phone service. And not just that, there are so many benefits as to why to choose this system. Few of

which includes:

1. Accessible “Anywhere/Wherever” you may be

2. Ideal for any communication application (Remote or Urban Location)

3. Takes Cable-Runs pain out of the equation

4. No limit to Communication Distance

5. 40-50-60 & More Stories Building Communication solution

6. Old Buildings Communication solution

7. Included 3-Mile Radius Antenna (Extremely Powerful)

System setup is simple, and we still continue to work towards improving every features/functions

currently available. Meanwhile, we will tell discuss available options equipped with this model in the

next pages.

System Communication Requirement:

As stated, system utilizes Cell-Phone Network to communicate with public network. Support

900/1800/1900-MHZ (2G, 3G, 4G) network. A regular SIM-Card similar to the one below can be

purchased almost anywhere.

To obtain one, visit your local cell-phone retailer and ask for a “STANDARD GSM SIM-CARD”. Most

carriers offer it for only one time payment of $10, which you can activate it right away simply by loading

card with prepaid minutes (Talk-time). Depending on the carrier, prepaid 1000-Talk Minutes average

cost is $10.00. System average talk time during call defaults to 120-seconds per call.

Initial System Assembly:

Panel consists of two parts: System Panel Mount Bracket / System Panel. System panel slide in to the

mount bracket, carefully remove mounting bracket by detaching from system panel. See illustration

below:

System Panel Housing Dimension

System Mounts Flush To Flat Surface/Wall


5 | P a g e

Panel With Mounting Bracket:

When detached, it will lead you to access to Main System Panel rear cover. Remove screws attached to

cover to access Main System Board (Please protect screws, Be extremely patient when performing this

process due to electro-magnetic static, and avoid touching Main Board. Be sure not to expose board to

any form of water, extreme heat, etc).

Inserting SIM-Card, 8-GB SD-Card, Antenna and other accessories will be discussed in the next page.

Exact board illustrative drawing available in next page should guide installer as to how and where to

locate SIM-Card Slot, SD-Card Slot, Power Supply input and Antenna wiring.

*****Important

Be sure to avoid connecting or placing accessories in the wrong spot as this could lead to system

operation instability.

System Board Diagram:

**Inserting SIM-Card

SIM-Card slot is located on the top right corner (Below SD-Card slot). (Insert Card Chip Side Down)

**Connecting Antenna

Antenna SMA Female Connector is located on the top left corner (Above System Processor). Antenna

comes with 6-feet wire; you can extend cable using SMA Coupler (female to Female). This can be

obtained at your local electronic store.

**Wiring System Power Supply

System comes with 1-15V 1.5Amp transformer, you can splice cable right in the middle and extend

wiring distance with 2-conductor wire to reach designated power source. If distance is less than 75-feet,

22-guage 2-conductor wire should be fine. But if distance exceeds 75-feet, we recommend 18-guage 2-

conductor wire. Thickness of this wire will maintain stable current flow for runs over 100-feet or more.

******Important Wiring Tips

It is highly recommended that you make use of included power supply. We do not recommend any third

party power supply, and if you choose to do so. Please consult system vendor to be sure that intended

third-party hardware will cause no harm/damage to system.

System Board

Wiring/Connection:

****Important (Network Configuration)

Make sure to follow wiring instruction as specified above. With loaded SIM-Card on board, nothing else

should be required to link system to public network. System should search, locate and establish

connection to the closest cell tower on its own.

Link Signal Meter/Indicator is located on the upper left corner of the screen. It will display signal link

strength between tower and system. Included antenna strength go as far as almost 2.5-miles, and it is

totally waterproof/weatherproof.

***Important*** +Linking Public Network Initial Identification by your service provider’s server actually depends on the proximity of the closest cell-tower to system location. Connecting this device to your service carrier’s network requires strong network signal to obtain successful handshake between carrier’s network and this device. If you are experiencing weak link signal, you can:

1. Take device to a different location and power on & off.

2. Relocate Antenna to higher level.
