Manual Control Points
These switches are used to manually open and close actuators in a smoke control system. There is
a set lock-out period of 5 seconds between successive operations. The actuators open full stroke in
response to a transitory operation of the Manual Control Point. However, to prevent finger trapping
issues, the actuators only close whilst the Reset button on the Manual Control Point is maintained.
Note that the default Manual control point close mode can be changed by SE Controls to close
fully in response to a brief press of the reset button. This mode change is only recommended
where the activated vent is at least 2.5M above ground level to minimise finger trapping issues.
OS2 MCP

OS2 Tamperproof MCP
Part Number FCS00200034
OS2 MCP Adaptor Plate
Part Number FCS00200017
All connections to the OS2 MCP are made via the connection PCB mounted
within the adapter plate assembly. (See diagram below.)
The connection PCB has 14 terminals, consisting of 2 pairs of 7 connections. For
OS2 products, it is only necessary to connect to 5 of these signals as follows:
