[SHAULA-V9] Basic Interface guide

In this brief post I would explain basics of interfacing SHAULA-V9 with any compatible security alarm system. SHAULA -V9 is a GSM/GPRS gateway that works as GSM and SMS gateway for security systems.

It is designed to be easily interfaced with a number of alarm security panels for example Pyronix 816 which I would use in the next post. In this post I would show the Interface of SHULA-V9 , focusing on the V9 ports. Lets start by knowing the different ports.

SHAULA-V9 Ports

1. 2 Connector for power (12V DC)
2. 8 (4+4) pin connectors for communication with alarm security system.
3. 2×10 pin connector for SHAULA-701.
4. Communication Port (Rs-485)
5. Gate Relay Pins ( NC- C – NO)
6. Door Relay Pins ( NC- C – NO)

Connector labelled 1:

The connector labelled 1 above is used to power SHAULA-V9. It requires 12V as a standard. Its important to note down the polarity. Its clearly marked out. GND should connect to - and Positive 12 V to +. If using a CAT-5 cable to connect to security board use BLUE wire to + and BLUE-WHITE to -.

connecting Power wires in reverse might damage the board

Connectors labeled 2:

SHAULA-V9 is designed to use a single Cat-5 cable to interface to security control panel. The ports on connector 2 are marked for Cat5 cable colors.

OR Connects to Orange wire of Cat-5, This is an active low Port that detects panic alarm signals. A low signal on this pin will trigger panic alerts.
OR' Connects to Orange-white wire of Cat-5, This is an active low Port that detects Alarm signals. A low signal on this pin will trigger alarm call and SMS alerts.
GR Connects to Green wire of Cat-5, This is an active low Port that detects Power Fault signals. A low signal on this pin will indicate that the main supply poer is OK if a low signal is not detected Power fault SMS will be sent.
GR' Connects to Green-white wire of Cat-5, This is an active low Port that checks the Arming mode. A low signal on this pin will mean that the alarm system is armed and if a low signal is not detected an armed condition will be considered .
BR Connects to Brown wire of Cat-5, This is an output wire, and produces signal to Arm or disarm Alarm system.
BR' Connects to Brown-white wire of Cat-5, This is also an output port and will .

Connectors labeled 3:

SHAULA-V9 is designed to work with SHAULA-701 which is a required part which connects through this connector.

Connectors labeled 4:

This port is reserved for Rs-485 based communication along with GND ,12V, Gate and Door Signals. In general use it isn’t used.

Connectors labeled 5:

This connector is used as outputs of Gate Relay.

Connectors labeled 6:

This connector is used as outputs of Door Relay.

There are some other ports which I haven’t covered in this post, these are reserved for testing and development purposes. In the next post I would explain how to interface SHUALA-V9 with Pyronix Matrix-816 and programming Matrix-816 for the purpose.
