PN Pneumatic controlled exit devices
The PN feature provides remote latch bolt retraction in
hazardous areas where electrically operated devices would not
be permitted. The pneumatic solenoid will retract the latch bolt
for momentary or prolonged periods. PN exit devices are
particularly suited for use with automatic door operators. The PN
feature is available on both Panic and fire exit hardware devices.
The PN feature includes a special actuating linkage that gives
building owners the option of mechanically or pneumatically
dogging the exit device. If manual hex-key dogging is required,
specify HD-PN (Dogging the device, whether mechanically or
pneumatically, makes the device function as a push/pull unit and
reduces the wear on its moving parts.) If cylinder dogging is
required, the standard cylinder dogging is not available, but
special center case dogging is available, specify SD-PN. SD-PN is
not available on the 9875 or 9975 devices.
When activated pneumatically, the latch bolt(s) of the exit
device retract in
1
/2₂ to 1
1
/2 seconds. This pneumatic operation
uses air pressure ranging from 50 to 100 pounds per square inch.
This product will function only when it is part of a pneumatic
system (air compressor, air lines, pneumatic system, etc.).
Contact LCN for correct control boxes.
To order, specify:
• Standard — Use prefix PN, example PN99NL
• Hex Key Dogging — Use prefix HD-PN, example HD-PN99NL
• Special Center Case Dogging (handing is required, specify
RHR or LHR) — Use prefix SD-PN, example SD-PN99NL
