in the Master Unit signals conditions (stand-by, Trouble / Alarm) to an alarm systems
panel. This panel controls the signal to the closer-holder solenoids in both the Master
Unit and the Tandem Unit.
These Closer-Holders are surface mounted to the push (stop)
side frame face. The standard mounting for these units require a minimum ceiling clearance
of 3-1/2" (89mm). Where ceiling clearance is between 2" and 3-1/2" (51mm
and 89mm) , the standard backplate for the 4220 Series or 4230 Series can be inverted to
allow for a drop application. Use of a No. 4299 decorative backplate is recommended to
conceal the exposed mounting holes on the standard backplate. Different mounting
dimensions are required for the drop application. The double lever arm mounts directly to
the door,. These units can be installed to accommodate door openings to 180º with a 170º
maximum hold-open point.
