Everything elevator emergency communication needs, in one device.
If one network drops, the other takes over.
Aselfon M8 works over both 2G and 4G. When 4G coverage weakens inside the shaft, the device falls back to 2G and keeps carrying the call. In emergency communication, downtime is not an option.
- 4G/LTE as the primary link
- 2G fallback — automatic switch when coverage drops
- External antenna connection for in-shaft coverage
Call is going over 4G
Whatever regulation asks for, the device does.
Elevator emergency communication is not an optional feature — it is a requirement. Aselfon M8 is designed to meet the communication requirements of the elevator standards in force.

Two wires. That's the installation.
The Aselfon M8 connects to the car with just two flexible cables. Inserting the SIM and commissioning takes minutes; no complex configuration.

Commission
The device attaches to the network and a test call can be made.
The machine room talks to the car.
The Aselfon M8 is not only an emergency phone that calls out — it is an intercom system inside the lift. The orange unit in the machine room talks either to the black B units on the car roof and in the pit, or to the black C unit inside the car. During maintenance the team can speak to each other between these points.
- Orange unit — machine room
- Black B unit — car roof and pit
- Black C unit — inside the car
Machine room ↔ car roof / pit
Whatever panel is in the shaft.
There is no single brand in the field. Aselfon M8 is designed to work with elevator control panels from different manufacturers — it integrates without replacing the existing wiring.
From a landline to dual network.
The real question is no longer analogue versus GSM: it is whether the device depends on a single network or uses two at once.
Analogue line (PSTN)
Classic landline intercom
Single-network 2G intercom
Common GSM devices on the market
Aselfon M8
2G + 4G dual network
Connectivity
A single fixed line — if it is cut, there is no communication
A single mobile network — no coverage means no communication
2G + 4G — if one drops, the other takes over
Infrastructure
A fixed line must be run to the building
A SIM card is enough
A SIM card is enough, with no operator restriction
Installation
You wait for a line to be allocated
Same day
Same day — two flexible cables to the car
Remote monitoring
Usually none
Most devices have none
Device status and call records can be viewed
Monthly cost
A separate line subscription for every lift
SIM subscription fee

Frequently asked questions about Aselfon M8.
If your question isn't here, write to us and our engineering team will answer it directly.
Aselfon M8 is an elevator emergency communication device (elevator intercom) that lets a person trapped in the car hold a two-way voice call with the outside. It places the call over the 2G and 4G mobile network instead of a fixed line. It is designed and manufactured in Denizli, Türkiye by Aselsis.
No. Aselfon M8 places the emergency call over the 2G and 4G mobile network, so no fixed (PSTN) line is needed in the building. Inserting a SIM card is enough.
Yes. Aselfon M8 supports 2G and 4G together. When 4G coverage weakens at its location, the device automatically falls back to 2G and keeps carrying the emergency call. An external antenna connection supports in-shaft coverage.
Aselfon M8 is designed with TS EN 81-20 (safety rules for the construction and installation of lifts), TS EN 81-28 (remote alarm on lifts) and TS EN 81-70 (accessibility for everyone, including persons with disability) in mind.
Aselfon M8 is compatible with elevator control panels from different manufacturers. It connects to the car with just two flexible cables, using labelled screw terminals; no extra interface board is needed.
The Aselfon M8 system has separate intercoms for inside the car, the car top, the shaft pit and the machine room. All of them connect to the Aselfon M8 main board, which carries the call out over the mobile network.
The Aselfon M8 box contains: the Aselfon M8 A board, two B intercoms, one C intercom, one machine room intercom, three 2-way and one 4-way female terminals, an antenna, the wiring diagram and user manual, and the in-cabin warning label. No extra parts need to be ordered for installation.
Aselfon M8 runs on a 12 V – 24 V DC supply. It is rated IP54 and designed to operate between -20 °C and +60 °C.
Aselfon M8 is commissioned in three steps: connect the device to the car with two flexible cables, insert the SIM card, then apply power and place a test call. No complex configuration is needed; installation takes minutes.
Yes. Aselfon M8 can also be run without a SIM card when needed. With a SIM card inserted, it carries the emergency call out over the 2G and 4G mobile network.
Yes. Aselfon M8 works as an intercom between the points of the lift. The orange unit in the machine room talks either to the black B units on the car roof and in the pit, or to the black C unit inside the car. During maintenance the team can speak to each other between these points.
Aselfon M8 has a standard SIM slot with no operator lock-in; it works with the SIM card of the GSM operator you choose. Contact Aselsis for line and subscription options.
Yes. Aselfon M8 works on its own; when connected to Aselmind, Aselsis's elevator management software, the status of every car, the record of every call and the maintenance plan are followed on one screen.
