Installing the BEAM-TM-L

Packing contents

• TM-L hardware unit
• 1× antenna
• Cable tie (for battery fastening)
• Vertical mounting bracket: packed separately, required only if Dynamic Monitoring is enabled

Installation orientation

Installation orientation depends on whether Dynamic Monitoring is enabled. Review the table below before mounting the device.

Mode	Installation requirement
Dynamic Monitoring ON	Sensor MUST be installed flat (horizontal). If wall-mounting, use the special vertical bracket (packed separately) to keep the sensor face parallel to the ground. Alarms only on X and Y tilt axes and all acceleration axes. Battery life will decrease.
Dynamic Monitoring OFF	Sensor can be installed in any orientation. No bracket required.

Gateway setup (GW 3.6.1)

Complete the following before commissioning any TM-L nodes:

1. Attach the LoRa antenna to the left port of GW 3.6.1.
2. Power on the gateway. Connect to its Wi-Fi hotspot: Ackcio_Beam_XXXX (password: [hidden on the public site]).
3. Open a browser and go to http://192.168.0.10. Log in with admin / [hidden on the public site].

Key differences when commissioning TM-L

The TM-L uses the same Nimbus 2.0 commissioning flow as other BEAM nodes, with two important differences:

• Cable: use a USB-C cable (not Micro USB) with the OTG adapter.
• Antenna: the LoRa antenna must be connected to the left port of GW 3.6.1 before starting. Also make sure the TM-L has its own antenna fixed on its port.

Battery

The TM-L uses a dedicated connector-type battery (2-pin XH2.54 mm male), different from the D-cell used in other BEAM Mesh nodes.

Parameter	Specification
Nominal Voltage	3.6 V
Capacity	19 Ah
Connector	2-Pin XH2.54 mm male
Max Continuous Current	>150 mA
Max Pulse Capacity	≥400 mA
Operating Temperature	−40°C to +85°C
Chemistry	Lithium Thionyl Chloride (Li-SOCl₂)

Approved battery models

• EVE ER34615 + SPC1550
• Tadiran TLP-93111-A
• Saft LSP 33600-20F

Battery replacement notes

• Replace within 1 month of a low battery alert appearing on the dashboard.
• Always use batteries manufactured within the last 3 months: Li-SOCl₂ batteries self-discharge during storage.
• Do not measure voltage directly with a multimeter without a load: Li-SOCl₂ always reads ~3.6 V regardless of state.
• There is no HPC in the TM-L, so there is no HPC deep-discharge risk. However, data loss on battery failure is permanent.

Device identification

Each BEAM TM-L unit has a unique label on its packaging:

• DevEUI: unique device identifier, equivalent to Ackcio’s 4-digit Node ID.
• Production Serial Number: for warranty and support tracking.
