Easy 2S

Reliable alarm signal transmitter and remote input monitoring device for dispatch and surveillance centers and for remote consumption metering tasks.

The communicator receives the incoming alarm signals of a connected alarm center in Contact ID format (CID code) and transmitts them to the dispatch center – or further destinations (IP address, IP receiver).

The device is also able to count and transmit the connected meter pulse signals.
It emits periodical life signals, has detection and notification capabilities of wire cut and sabotage.

The output line can be switched remotely (for gate opening, device control).

It is suitable for alarm signaling, input monitoring (through its IOs) and remote control for companies, safety and utility providers.

The device can be ordered in 2G / 3G / 4G versions.

You can increase the efficiency of your current wired alarm system and safety surveillance service by using our wireless device as backup alarm transmission channel (GSM voice or data), or using it as a primary route to the centre, by connecting sensors, it may also control external devices.

In autonomous mode, it operates as a complete alarm system (without using an external alarm system), which you can arm/disarm manually by remote controller (i.e. a panic button) or through a mobile phone app.

Alarms or events can immeadiately be notified by SMS text messages (up to 4 phone numbers).

You can extend the system with further IOs (due the optional expansion PCB). Connect a siren, a spare battery pack, a sabotage switch to the device and provide thus the highest level of safety for your home, office, company.

It is easy to configure (remote, locally by a free tool), easy to use. The communicator can be accessed remotely.
