in the Master Unit controls the closer-holder solenoids in both the Master Unit and the
Slave Unit.
Master Unit x Tandem Unit: Smoke Detector
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 requires a minimum ceiling
clearance 3-1/2" (89mm). Where ceiling clearance is between 2" and
3-1/2" (51mm and 89mm) the standard backplate for 7220 Series or 7230 Series can be
inverted to allow for a drop application. Use of a No. 7299 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 180°
with a 170° maximum hold-open point.
