Access Unit 7320.220
Description:
The electro-magnetic handles can be connected to the Access Unit 7320.220 (max. 2). The handle functions as a door interlock
and grip lever monitor. An access sensor for each handle must be mounted on the controlled door. If the grip lever are closed,
the interlock coil integrated in the handle locks automatically. The handle can be released through the CMC-TC system in the
network or through optional extra systems, e.g., a chip card reader (7320.750), magnetic card reader (7320.760), number code
lock (7320.770) or an individually settable floating switching contact (7320.580).
Attention. The handle open by an electrical connection, only. By open the handle it’s necessary to have a release by the
electrical CMC-TC and by the push-button.
The handle is assigned a code to ensure that it is identified and set up automatically by the CMC-TC system. The following
components are required for operating the handle:
- Processing Unit (7320.100) min. SW V 1.1 with mains adapter (e.g., 7320.425), connecting cable complying with local
