Pneumatic Output Module
The Pneumatic Output Module (Figure 3) contains the
transducers that provide the signal conversion from
electronic to pneumatic. Three modules are used per
controller. The gauge on the module provides a
readout of the pneumatic control signal. This can be
used during system start-up and troubleshooting.
Specifications
Maximum Input Pressure 30 psi
Air Consumption 4 SCIM (1.1 ml/sec)
Power Consumption 1.5 VA @ 24 Vac max.
Dimensions 2-1/2" W x 4-1/2" H x 1-1/4" D
(64 mm x 114 mm x 32 mm)

Room Pressurization Controller Pressure
Mode Switch
The Room Pressurization Controller Pressure Mode
Switch changes the pressurization of the room from
protective isolation (positive), to infectious isolation
(negative), to no isolation. This keyed switch also
includes a light to indicate when the controller is not
able to maintain the programmed differential flow in
the room. The stainless steel flush mounted switch
can be mounted outside a patient/treatment room or
at a nurse’s station.
Specifications
Power Consumption 1.1 Va @ 24 Vac max.
Dimensions 4" H x 4.5" W
(102 mm x 114 mm)
Weight 1 lb (0.4 kg)
Room Pressurization Controller
Communication
Up to 32 Room Pressurization Controllers or other
Terminal Equipment Controllers can be connected to
each of the three Protocol 2 field panel LAN trunks, for
a total of 96 per field panel. Communication with the
Room Pressurization Controller can be initiated from
any APOGEE Automation System field panel on the
system network (Figure 5). The APOGEE Automation
System network does not require additional hardware
to connect Terminal Equipment Controllers. When
Terminal Equipment Controllers are wired to a field
panel, features such as energy management
programs, alarm reporting, centralized control,
modification of the system database, system-wide
troubleshooting, and the global commanding of
devices are available to them.
Portable Operator’s Terminal
The DOS-based laptop computer serving as the
Portable Operator’s Terminal can communicate with
Room Pressurization Controllers or any field panel. The
terminal connects to the controller via the plug-in jack
on either the controller, the room temperature sensor
associated with the Room Pressurization Controller, or
a Protocol 2-field panel. The terminal can be used to
remotely adjust air volume settings or temperature set
points, to troubleshoot, and to start up the system.
When connected to the RS-232 port of a Protocol 2-
field panel, the terminal provides system-wide
communication. The terminal uses full English
language for all functions, eliminating the need to
remember coded commands.
