BAPI-Stat “Quantum Prime” Temp & Humidity Sensor

Overview and Identication

The BAPI-Stat “Quantum Prime” is designed for operating rooms,
clean rooms and elder care facilities. It features a large display
and membrane keypad for wipedown cleaning. It is available with
temperature and humidity measurement, temperature and humidity
setpoint and occupant override.

The unit includes a number of eld adjustments including °F or °C
display, temperature and humidity offset and setpoint lockout. The
display can also be set to show a large temperature and small %RH
reading or a large %RH and a small temperature reading when
4 buttons are present. This unit can be congured with up to four
transmitted variables. Contact your BAPI representative for details.

JUNCTION BOX

1. Pull the wire through the wall and out of the junction box, leaving
about six inches free.

2. Pull the wire through the hole in the base plate.

3. Secure the backplate to the box using the #6-32 x 1/2 inch
mounting screws provided.

4. Terminate according to the guidelines in the Termination section.

5. Attach cover by latching it to the top of the base and rotating the
cover down. Secure the cover by backing out the lockdown screw
using a 1/16” allen wrench until it is ush with the bottom of the
cover.

DRYWALL MOUNTING

1. Place the base plate against the wall where you want to mount the
sensor.

2. Using a pencil, mark out the two mounting holes and the area
where the wires will come through the wall.

3. Drill two 3/16” holes in the center of each marked mounting hole.
Insert a drywall anchor into each hole.

4. Drill one 1/2” hole in the middle of the marked wiring area.

5. Pull the wire through the wall and out the 1/2” hole, leaving about
six inches free. Pull the wire through the hole in the base plate.

6. Secure the base to the drywall anchors using the #6 x 1” mounting screws provided.

7. Terminate the unit according to the guidelines in the Termination section.

8. Attach cover by latching it to the top of the base and rotating the cover down. Secure the cover by backing out the
lockdown screw using a 1/16” allen wrench until it is ush with the sides of the cover.

Fig. 2: Mounting hardware is provided for

both junction box and drywall installation

(Junction box installation shown).

Note: In any wall-mount application, the wall temperature and the temperature of the air within the wall cavity can cause
erroneous readings. The mixing of room air and air from within the wall cavity can lead to condensation, erroneous
readings and sensor failure. To prevent these conditions, BAPI recommends sealing the conduit leading to the junction
box with berglass insulation.

Termination

BAPI recommends using twisted pair of at least 22 AWG. Larger gauge wire may be required for long runs. All wiring
must comply with the National Electric Code (NEC) and local codes. Do NOT run this device’s wiring in the same conduit
as AC power wiring of NEC class 1, NEC class 2, NEC class 3 or with wiring used to supply highly inductive loads such
as motors, contactors and relays. BAPI’s tests show that uctuating and inaccurate signal levels are possible when AC
power wiring is present in the same conduit as the signal lines.

BAPI recommends wiring the product with power disconnected. Proper supply voltage, polarity, and wiring
connections are important to a successful installation. Not observing these recommendations may damage the
product and will void the warranty.

Terminal Notes: (Related to Table 1)

V+: Power. See Power Supply specications.

GND: Ground/Common for V+, OUT1, OUT2, OUT3, OUT4, and

TEMP- terminals when congured as Common Ground (default)

OUT1: Temperature, Temperature Setpoint, or Humidity Setpoint with
voltage or 4 to 20mA output.

OUT2: Humidity, Temperature Setpoint, or Humidity Setpoint with
voltage or 4 to 20mA output.

OUT3/OUT4: Temperature Setpoint or Humidity Setpoint with voltage
or resistive output. Resistive output can be wired as Differential
Ground. Optional override available.

TEMP+/-: Resistive temperature sensor. Optional override available.
Used as input for external sensor option (-ES). External sensor must
be a 10K-2 thermistor purchased separately (max wire length of 25ft).
A humidity output or resistive temperature sensor are not allowed in
this conguration.

EXT OVR: Wiring of the J6 External Override (EXT OVR) terminals is
not covered in this section. It is described in the “Override Display Icon
Activation” section on page 4.

See product label for conguration and termination information.
