Installation Guide

Centurion Systems (Pty) Ltd www.CentSys.com

1. Introduction

The G-SWITCH-22 GSM Module allows up to 1200 individual users to activate a maximum of two outputs on the Module using their mobile phones.

These outputs can be used to open a gate, activate an alarm system,

Missed Call (free), Please Call Me message (free), or a pre-specified text message (SMS).

In addition, users can also be notified by SMS, of the activation of either of the two Inputs on the Module, in the event of an alarm activation, a power failure, etc. The Input Module of the G-SWITCH-22 can be configured to react to rising, falling or both edges, and different messages can be set for rising and falling edges. It also boasts adjustable

Filter and Blanking Times and an event counter, all of which are discussed in detail in the ‘Special functionality’ section of the separate Programming

Guide. The secure, online G-WEB portal provides another means of programming and administering your G-SWITCH-22 and gives you access to several advanced features.

The Module is over-the-air bootloadable via the G-WEB interface, meaning that it is not necessary to waste precious time and fuel to go to site, and updates to the firmware etc, can be done from the comfort of your home or office.

2. Important Safety Instructions

1. All installation, repair, and service work to this product must be done by a suitably qualified person.

2. Do not in any way modify the components of the system.

3. Do not install this product near sensitive electrical components.

(e.g. the DOSS sensor inside a gate motor housing)

4. Do not install the equipment in an explosive atmosphere: the presence of flammable gas or fumes is a serious danger to safety.

5. Do not leave packing materials (plastic, polystyrene, etc.) within reach of children as such materials are potential sources of danger.

6. Dispose of all waste products like packing materials, according to local regulations.

7. Centurion Systems does not accept any liability caused by improper use of the product, or for use other than that for which the automated system was intended.

8. This product was designed and built strictly for the use indicated in this documentation. Any other use, not expressly indicated here, could compromise the service life/operation of the product and/or be a source of danger.

9. Anything not expressly specified in these instructions is not permitted

This icon indicates tips and other information that could be useful during the installation.

This icon denotes variations and other aspects that should be considered during installation.

3. Security Consideration

It is strongly advised that a pre-paid SIM card (with limited airtime) is used, and that it is also PIN-code protected. These measures will give you peaceof-mind as they will ensure that your SIM card will have little or no value should it ever get stolen. Record the IMEI of your G-SWITCH-22 in the blocks provided in Section 6. In the event that the G-SWITCH-22 is stolen, you can use the IMEI number to blacklist the G-SWITCH-22.

4. General Description

The G-SWITCH-22 GSM Module uses the GSM mobile phone network to enable remote control and communication between itself and up to 1200 authorised users via their mobile phones.

A valid, activated SIM card is required in order to use the Module on the

GSM network.

When programming the G-SWITCH-22 , each user’s phone number can be set to:

& Activate a specified output with a Missed Call (free)

& Activate either output via a unique, user-defined SMS or one of twenty pre-programmed default SMSs (more convenient)

& Be notified by a unique, user-defined SMS of either of the two Inputs being activated

& Activate Output 1 via a free Please Call Me message

& Programming of the Module is password-protected

& All users calling or sending an SMS to the Module need to ensure that their Caller Line Identification Presentation (CLIP) is activated on their phone to ensure that the Module recognises the user’s learned-in phone number

& Contract SIM cards used in the G-SWITCH Module also need to have CLIP enabled

& The Module requires a power supply of 11V-30V DC, capable of delivering 500mA peak current

& Both outputs are potential-free, and rated to 30V DC @ 1A

& Both normally-open and normally-closed contacts are provided

& Inputs can be set to react to falling or rising edges, or both

8. Mounting Instructions

The housing of the G-SWITCH-22 is weatherproof, allowing it to be mounted externally in order to receive the maximum GSM network signal.

However, the unit can be mounted inside the housing of the device that it is operating, such as the gate motor if the GSM network signal is adequate

(refer to Section 11 – GSM Network Signal Detection).

The following section describes the procedure for mounting the unit to either an internal or external wall. If mounting the G-SWITCH-22 externally, give consideration to its location as it should not be within reach of unauthorised persons.

11. GSM Network Signal Detection

When powered up, the G-SWITCH-22 signal strength indicator LEDs will light up indicating the GSM network signal strength.

The GSM signal strength can be determined based on the combination of the three LEDs that illuminate:

The signal strength can be queried by sending the ‘Request signal strength’ command (p.xxxx.CO.SS) to the Module.

The querying phone will receive a reply SMS with a value of 5

(strongest) to 1 (weakest) indicating the signal strength.

The GSM signal strength may be enhanced by repositioning the antenna.

Ideally the antenna should be mounted externally, and away from any sensitive electrical components.

Double-sided tape

Antenna

The rear side of the antenna has a double-sided tape backing, which may be used to affix the antenna to a desirable location. Please ensure that the surface to which you affix the antenna is smooth, clean and dry, to ensure reliable adhesion.
