Modular Digital System for Lift Emergency Communication
2N Lift8 is a highly modular lift emergency communication system. Its two-wire bus means it can be installed in any lift without new cabling. One central unit handles up to 8 independent shafts, each with up to 6 audio units, and you can choose PSTN, GSM, UMTS or VoIP to reach the operator. For firefighter lifts, the Fireman Unit meets EN 81-72.
No new cabling
On one central unit
Swappable modules
Fireman lift unit
2N Lift8 is built for multi-shaft projects and strict standards, and upgrades to new technology by changing a single module.
Whatever communication technology you use, two wires in the travelling cable connect up to 6 audio units in one shaft and the machine room
One 2N Lift8 Central Unit with one SIM card handles emergency calls from up to 8 independent lift shafts
Add an RS232 or LAN module to the central unit for remote monitoring of the lift controller's status
Meets the requirements of lift standards, with an integrated backup battery and a Fireman Unit for firefighter lifts to EN 81-72
Choose PSTN, GSM, UMTS or VoIP for emergency communication, and switch technology by replacing just the module
Configure locally with the supplied software, or remotely by voice menu, SMS or software application
Sends a visual record of the cabin during an emergency or on operator request, and can record to a microSD card at set intervals
Configure a complete Lift8 system locally (USB) or remotely (IP), view an online diagram of all units and upload your own messages
