GSM UNIT 

 

 

 

1. INTRODUCTION 

The GSM unit enables the PowerMax+ system to operate over 
cellular network. GSM unit features are as follows: 

A.  PowerMax+ fast upload/download capability via the GSM unit. 
B.  Sending SMS and voice messages to private telephones. 
C.  Communication with central station (SIA, Contact ID format). 
D.  Serving as PowerMax+ telephone line backup, as a primary 

communication channel, or as the only telephone channel. 

E.  Sending SMS messages to central station. 
F.  Two-way audio communication between telephone user and 

PowerMax+ user. 

G.  PowerMax+ remote arming. 
H.  Remote activation of home appliances. 

I.  Remote PowerMax+ system monitoring (status, failures). 

J.  Enables calling the PowerMax+ by a single dialing (it is not 

necessary to dial, hang up and then redial). 

K.  Tamper and line disconnection protection. 

The unit includes the following LED indicators (see figure 1):

The GSM unit includes a GSM cellular modem, backup battery 
pack and Tamper protection switch. 
The GSM unit's backup battery is charged by the PowerMax+ or 
by an AC power supply. 
When PowerMax+ telephone line is disconnected, the 
PowerMax+ uses the GSM unit instead of the regular telephone 
system, according to GSM LINE PURPOSE definition (for details, 
refer to the PowerMax+ Installer Guide, section 4.6). 
The GSM unit and the PowerMax+ periodically check the 
connection between them. When the connection is lost, both 
report a Tamper alarm. If either unit is tampered with, the other 
unit reports the event. 
In case of GSM unit low battery voltage or GSM line failure, the 
failure message is reported to the PowerMax+. 
The GSM unit must be enrolled in the PowerMax+ system (see 
PowerMax+ installer guide, section 4.6 - Defining GSM Parameters). 
SIM card (see figure 2) with 3 volt or 5 volt technology should be 
inserted into the GSM unit so that the unit can be connected to 
the cellular network with a defined telephone number.
