Also, the power supply should be protecting the battery from deep discharge and maintain short-circuit power output of 12 V. The fourth option – it is desirable that the system had Remote led display, which allows you to visually monitor the status of the device. It is very important when using electronic switches such as Touch Memory, key fobs and cards for remote arm and disarm the device with protection. The fifth option: it is necessary for the system to a single message more fully describe the state of the system of protection, For example, an alarm indicating the zone in the state of GSM-system, describe how the relay protection included how much charge is left in the battery, what is the telephone line (if any). There are additional optional parameters – For example, depending on their level of GSM-protection can not only inform the owner about the problems of protection, but also independently to respond to such stimuli. Since attackers can, and block the cellular network in District with a simple cellular "jammers", it is important that, in response, say, the invasion, the system is not just going over numbers to send sms messages as "happy" news, and immediately use alternative methods delivery of the message or include sirens, opened the cells with the dogs, bodyguards, the light on, or allowed tear gas. The sixth option – it is very important to know how to burglar alarms to monitor the availability or no signal from the base station.
Virtually all models GSM-signaling devices used by an attacker or suppress signal interference is a problem, but solvable. The system simply must be able to to signal an alarm prior to the owner of the building or premises with a deterioration of signal quality from base station. And in the absence of the main channel – use alternative. So, to summarize. Principle gsm security alarm system works is as follows: the device has multiple inputs for sensors and multiple outputs for the actuators, as well as cellular gsm module. When firing one or several sensors (motion, smoke, volume, noise, and others) are connected to the input device, alarm system gsm security immediately dials or sends SMS-messages to preset numbers.
Simultaneously, the trigger appropriate actuators. For example, in the event of a fire extinguishing system activated. Manage the work of GSM-alarm system remotely via a telephone call or an SMS-message. Main differences and advantages of the GSM-alarm systems: * Completely wireless gsm alarm system: does not require wiring, walls of other construction-related violation of the interior. * Very easy to install and service: installation and configuration of gsm signal from a layman takes 15-30 minutes. * Independently deters intruders inclusion of a powerful siren and simultaneously begins to auto dialing, sending sms and voice messages specified phone number. * Has built-in capacity battery, allowing gsm alarm systems work without electrical connections to 5 days. * Works and sub-zero temperatures, so the complex can be operated in winter in unheated spaces, such as: garage, summerhouse, storage and others. * The control panel has a built-in microphone allows you to remotely listen to the room with the phone. * Cheaper existing Today analogues. * Has a single control panel with built-in receiver-transmitter, GSM-modem and programmer.
