option the HHC system can store 387 sets of pressure
measurements. Sets of pressure measurement data
include pressure measurement from the left, right or
both modules.
If data storage is done without the time/date stamp
option the HHC system can store 714 sets of pressure
measurements. Sets of pressure measurement data
include pressure measurement from the left, right or
both modules.
Step 8 Using the arrow keys select the desired stor-
age format. The desired format will flash on the display
when selected.
Date/Time Stamp

hazardous areas it was necessary to disable this function.
The HHC can be equipped with a set of single pole
single throw (SPST) relays for use in triggering annun-
ciator lights, fans, sirens, etc. The relays have the fol-
lowing specifications:
Relay Specifications
Parameter Specification
Switch Arrangement: Form C
Resistance (max): 50 micro ohms
Switching Power (max): 30 W, 62.5 VA
(resistive load)
Switching Voltage (max): 110 V dc, 125 Vac
Switching Current (max): 1 Amp
Switching Capability (min): 10 micro amp, 10 mVdc
The relay contact closures are accessed through the 9
Pin female D connector on the right side of the HHC.
Pin out information for set point contacts is as follows
