Operating without additional equipment
Easy equipping of a small shopping pavilion or other property with a standalone or stationary autonomous alarm button without the installation of other expensive systems — that’s exactly the kind of job that the Contact GSM-1 is designed to do.
Operation of the alarm button doesn’t require any additional modules or devices: all it needs is to be connected to an external power source or periodically charged. For this very reason, the button can be used as a stationary solution.
Unlike radio-channel (433 MHz, 868 MHz) alarm buttons, the Contact GSM-1M works everywhere covered by GSM communication, without the need for relays or other equipment.
Compact size
The device’s small dimensions allow it to be concealed in places not visible to an intruder, such as the space under the display window or cash register.
This device interfaces directly with GEO.RITM software. You can use your free account at eu.ritm.ru to easily connect up to three portable alarm buttons or other devices of Ritm company. The Contact GSM-1M can also operate on your personal GEO.RITM virtual machine, where needed.

Additional hardwired zone
The Contact GSM-1M is equipped with terminals for connecting an additional hardwired zone. A wired alarm button could be connected as such a zone. The normal state of the input is customized — just like the events forming actuation of the main and additional zones.
Power supply
Uninterrupted operation of the alarm button is achieved thanks to its powerful replaceable battery. Main power comes from the 220/9V power adapter. In the event that primary power is disrupted, the alarm button switches to operating off of its built-in backup power source — the 16650 2500 mAh replaceable battery. Average operating time when running on the fully-charged battery is 40 hours.
Remote antenna
In order to increase the reception area of the GSM signal, we’ve equipped the alarm button with an external connector for a remote antenna. If the coverage zone of the GSM-network where the
Contact GSM-1M is operating is unstable, you can use a special high-sensitivity antenna or take an even more drastic approach: connect the remote antenna using a long cable with high amplification.
Expanded indication
Compared to its predecessor, the Contact GSM-1M alarm button features an indication of the operation of the rechargeable battery (RB) and the recharging process: it is divided into three separate areas — RB-based operation, button charging, button charged. This results in the greater information yield of the device.
