Autonomous Switching Device ROSSMA® IIOT-AMS ESD (Equipment Security Device)

ROSSMA IIOT-AMS ESD autonomous meter-switch is an autonomous device equipped with sensitive elements designed for monitoring the security of static objects. When placed on protected equipment, it ensures its safety by transmitting messages about the activation of sensitive sensors installed in the switch, which react to attempts to dismantle or destroy protected static equipment.

ROSSMA IIOT-AMS ESD is a device equipped with sensitive elements that register:

• housing tilt at an angle of more than 15 degrees;
• vibration and impact on the device housing;
• vibration and impact on the equipment housing to which ROSSMA IIOT-AMS ESD is attached using a piezoelectric sensor.

Housing tilt sensor registration along the horizontal axis and registration of vibration and impact sensors on the housing is performed continuously. Data transmission period can be configured from 1 minute. By default, manufacturer sets data transmission interval to once per day. Data transmission is performed by a timer set in the meter-switch's internal memory.

Capabilities

Additionally, it is possible to connect external security and fire sensors of the following types to ROSSMA IIOT-AMS ESD:

• Contact – control of door, gate, window opening;
• Motion – detection of movement inside protected zone (premises, territory);
• Acoustic – detection of glazed structure destruction;
• Vibration – detection of impact, increased vibration in protected zone (wall, equipment housing, perimeter fence, pipelines, masts, etc.);
• Water leak indicator – leak detection when device contacts liquid;
• Gas leak sensor – detection of increased gas concentration (methane, propane, carbon monoxide, etc.);
• Tilt sensor – response to protected equipment position change;
• Temperature sensors – detection of temperature exceeding threshold;
• Smoke detectors – smoke detection in protected zone;
• Manual call points (alarm buttons) – manual alarm signal generation by witnesses (workers, duty personnel).

LED Indication

The meter-switch has indicators ACT (trigger), Lora (sending/receiving data via LoRaWAN network). The meter-switch has a RESET button – device reset, pressing which causes device reboot.

First Start

IMPORTANT: To ensure proper functioning, installation and configuration of the meter-switch must be performed by qualified personnel.

Connecting the meter-switch to power must be done in the following order:

1. Install meter-switch according to mounting type
2. Unscrew screws (4 pcs) securing cover to housing base
3. Remove cover
4. Install jumper on power contacts
5. Check LED indication
6. Secure cover to housing base with screws

Tip: After first start, device will automatically begin registering in LoRaWAN network. Make sure it is registered on ROSSMA NETS server before powering on.

Battery Replacement

IMPORTANT: Battery replacement must be performed by qualified personnel. Repair and maintenance of meter-switch by consumer is not allowed!

Approximate battery life up to 10 years with data transmission once per day.

CRITICAL: Use only non-rechargeable lithium-thionyl chloride (LiSOCl2) battery ER34615M/T manufactured by FANSO. Attempts to charge the battery may cause fire!
