- Communication port for monitoring or diagnosing external devices RS-232 (or RS-485 as an option)
- USB-C port for configuration
The specialised alarm module for lifts, MT-514, is a dedicated, professional device that meets the requirements of the PN-EN 81-28:2022-11 standard, ‘Remote alarm in passenger and goods-passenger lifts’. The module enables status monitoring on 8 binary inputs, control of 5 outputs, establishment of a voice connection with the service and playback of stored voice messages. Some unused outputs can be configured as inputs. It also allows monitoring of the emergency power supply status using a voltage analogue input. The module has a USB-C port for configuration, an RS-232 (or optional RS-485) communication port and an Ethernet port.
Due to the wireless nature of the GPRS/LTE transmission used, the module is used in cases where there is no access to traditional telephone lines or when it is necessary to increase the reliability and optimise the operating costs of alarm and monitoring systems.
Thanks to the compact design of the device, the integrated GPRS/LTE modem, and the appropriately selected technical parameters enabling direct cooperation with the standard intercom in the lift cabin, the MT-514 is an optimal solution for both newly constructed and currently renovated passenger and goods lifts.
- Dedicated opto-isolated alarm/binary input with adjustable reactivation delay (labelled ALARM)
- 7 additional opto-isolated binary inputs with adjustable reactivation delay
- AUDIO output suitable for standard ‘4+n’ intercoms
- 4 opto-isolated, universal high-side binary outputs that can be converted into binary inputs
- 1 NO/NC relay output
- 10Base-T/100Base-TX Ethernet port with DHCP server
- RS-232 port (or optional RS-485) for connecting external devices (monitoring, diagnostics)
- RTC real-time clock
- Internal non-volatile memory for configuration data with remote update option
- Transmission modes
- GPRS/LTE – packet transmission
- SMS
- AUDIO
- The Ethernet port on the device allows it to work in two modes: as a client, where it can work with any network, providing communication with servers and other systems, and as a router with NAT, which makes the Internet available to other devices through a built-in 2G/4G modem with a SIM card. In router mode, it can also act as a DHCP server, automatically assigning an IP address to the connected device. This solution offers flexibility of integration and extensive network configuration options.
- VoLTE – the option to make phone calls via LTE technology
- Option to send SMS/GPRS alarm messages to the service centre when the ALARM input is activated, the status of the binary input or output changes, the device restarts, the mobile network is logged on to or a voice connection is ended
- Software-adjustable inactivity time of the ALARM input to reduce the number of unjustified alarm messages in case of multiple consecutive alarm activations
- Programmable filtration constant for binary inputs
- Automatic confirmation of voice call execution
- Diagnostics of the AUDIO path including alarm connection test
- Option to transfer data to/from devices connected to the communication port (optional)
- Option to change the module’s configuration parameters remotely
- Protection against unauthorised access in the form of a list of authorised phone numbers and IPs, optional configuration password
