Smart Padlocks for Telecom Base Stations and the Power Grid
Telecom towers and power-grid installations are where most of our 4G-BLE-093 padlocks work: fence gates, equipment shelters, battery cabinets, substation gates and roadside grid cabinets. Each opens only for the right person, at the right site, in the right time window — and raises an alarm the moment it is cut or forced.
Security and maintenance at every tower site
A tower company or operator runs thousands of unattended sites, visited by its own crews, contractors and — on shared towers — other operators. The padlock has two jobs: keep thieves out, and let the right technician in without a key.
Battery and fuel theft
Backup batteries, generator diesel and cable are what thieves come for. A cut or forced lock raises an alarm at once, with the site and the time, while there is still time to act.
One lock for every door
Fence gate, equipment shelter, outdoor cabinet, battery cabinet. The shackle version locks doors and hasps; the steel-cable version seals fuel caps and awkward lock points.
Maintenance by work order
The NOC issues access for this technician, this site, these hours. Contractors and tenants on shared towers get exactly the sites they are working on, and nothing else.
Opened from the NOC
A technician at the gate without the app? The control room can open the lock remotely over 4G, and the opening is still recorded against the work order.
No keys in circulation
When a contract ends or someone leaves, access is withdrawn on the platform in one step. There is no key to recover and no lock to re-key across a whole region.
Proof for every site visit
Who opened which site, when, and when it was locked again. Disputes over SLA visits and missing equipment are settled from the log, not from memory.
From substation fence gates to roadside cabinets
A grid company has lock points spread across a whole service area: substations, switchgear rooms, ring main units, box-type transformers and metering cabinets. Most are unattended; many are opened by contractors.
Substation fence gates
The perimeter gate is the first line. Every opening is tied to a named person and a work order; a forced gate raises an alarm.
Switchgear rooms and ring main units
Only an authorised, qualified person opens equipment doors, and only inside the window of their job. Everything else is refused and recorded.
Box transformers and grid cabinets
Roadside equipment is exposed to tampering and theft. The lock reports the attempt instead of waiting for the next inspection to find it.
Metering cabinets
A recorded opening history on every meter cabinet helps a utility trace interference with metering equipment.
Contractors across a wide area
Access is issued per job and expires on its own. Nobody drives out to hand over or collect keys.
One audit trail for the network
Every opening, every refused attempt and every alarm, for every site, in one platform — and available to your own systems through the API.
Access by work order, not by key
Bind the lock to the site
Each padlock is registered on the platform against its site and the door or cabinet it protects. Rights are set per site, per time window and per person.
Issue the work order
Operations issues the work order: which site, which technician, which hours. The authorisation reaches the technician’s app.
Open on site
The technician wakes the lock and requests the unlock in the app; the platform checks person, lock and time window and opens it over 4G or through the phone over Bluetooth. Anything else is refused and recorded.
Lock and close the order
Locking is recorded as well, so the log shows the site was secured again and by whom. When the window ends, the rights expire on their own.
Which padlock for which site
For most tower sites and grid installations, the 4G-BLE-093. The others fit where coverage, lock count or budget call for them — all on the same platform and app.
| How it opens | Power at the lock | Best for | |
|---|---|---|---|
| 4G-BLE-093 4G + Bluetooth · recommended | Requested in the app, or released remotely from the platform | ER18505M cell, over 12 months | Tower sites, shelters, battery cabinets, substation gates, grid cabinets — wherever a cut or forced lock must raise an alarm at once |
| LORA_BLE_098 + gateway LoRa | Remotely from the platform through the gateway; on site over Bluetooth | 4,000 mAh cell, over 1 year | Many locks at one site — a large substation or plant — or no public coverage |
| ABD_BLE_806 Bluetooth | In the app on site; works on cached authorisation with no signal | Over 2 years | Indoor equipment rooms and inspection rounds where staff always carry the app; no SIM, no monthly fee |
| PLC-40 + FPB-02 Passive | Fingerprint on the key; the work-order permit is carried by the key | None — the key powers the padlock while inserted | Thousands of distribution cabinets where a battery in every lock is impractical. New design, samples on request |
Battery life is at normal use and depends on how often the lock is operated and how often it reports. The cell is replaced on site with the supplied spanner. The cellular module is supplied in regional band versions.

Frequently asked questions
What happens when a technician or contractor leaves?
Their rights are revoked on the platform in one step. There is no key to recover and no lock to re-key. Work-order rights also expire on their own when the time window closes.
How fast does a theft alarm reach us?
A cut or forced 4G-BLE-093 wakes and reports over 4G at once. The alarm appears in the platform with the lock, the site and the time, and in the app of the people responsible.
Some sites have weak or no mobile coverage. Will it work?
The 4G-BLE-093 opens over Bluetooth from the technician’s phone as well as over 4G. For sites with no public coverage at all, the LORA_BLE_098 works through a gateway on site, and the Bluetooth padlock opens on the authorisation already cached in the app.
Can several operators share one tower site?
Yes. Rights are issued per site and per person, so each tenant’s technicians open only the locks they are authorised for, and the tower owner sees every opening.
How long do the batteries last?
4G-BLE-093: over 12 months at normal use; how often the lock is operated and how often it reports decide the real figure.
The cell is changed on site with the supplied spanner, and the platform warns of low batteries early so they can be changed in batches on a routine visit.
Can it connect to our NOC or work-order system?
Yes. The platform has an open API, or we deploy a dedicated copy on your own servers. The hosted platform has no platform fee, licence fee or per-call charge, and your authorisation rules, users and data stay yours. See Platform & App.
