PARAGON CONTROLS SPM-1000-IOM Guardian Space Pressure Monitor Instruction Manual
BASIC OPERATION
The Guardian is a complete system package consisting of space and reference pressure sensors and the central signal processing module. The central module measures and displays the pressure differential with a resolution of up to one ten thousandth of an inch water column. The LED display can be factory set for engineering units of either Inches Water Column or Pascals. An analog output which is linear to the pressure differential is provided for remote monitoring, control and data logging. An alarm condition will occur when the space pressure falls outside the preset operating range. During an alarm condition a local LED will illuminate, a local audible alarm circuit will be enabled, and an alarm relay shall energize for remote alarming purposes. An optional remote auxiliary alarm is available with an adjustable delay which will activate a local LED and the audible alarm. A key locked front panel allows for controlled access to the field configurable functions of the Guardian. These functions include pressure alarm setpoint adjustment, audible alarm on/off selection, adjustable delay of the pressure alarm to prevent nuisance alarms which would occur due to normal foot traffic, and differential pressure transducer calibration.
GUARDIAN FEATURES
2.1 POWER SUPPLY
The Guardian utilizes an isolated linear type power supply generating +15vdc and ∀5vdc to power the pressure transducer sensor, scaling and digit circuitry. Input power to the Guardian is 24VAC. The power supply is fused with a 3/8 Amp Slow Blow Pico fuse, located near the input power terminal.
2.2 ALARM STATUS
Both Normal and Alarm operating status is locally indicated via LED•s on the Guardian face plate.
2.3 ALARM SELECTION
The Guardian can be field configured to provide either Positive or Negative room pressure alarming function. In the Positive mode the alarm activates when space pressure falls below the alarm setpoint value. When in the Negative mode the alarm activates when space pressure rises above the setpoint value.
2.4 AUDIBLE ALARM ACKNOWLEDGE
Muting of the local audible alarm during a loss of the required pressurization level. The audible alarm circuit shall be reset once the monitored pressurization level is within the acceptable operating range.
2.5 REMOTE ALARM RELAY
A single-pole double-throw relay is energized whenever the space pressurization level is outside of the acceptable operating range.
2.6 REMOTE ROOM PRESSURE SELECT
The Room Pressure Monitor can be configured for positive or negative room monitoring remotely by the closure of a dry contact.
2.7 REMOTE AUXILIARY ALARM
The auxiliary alarm can be activated either by a contact closure or contact opening. The alarm can be delayed up to 30 seconds and will activate the audible alarm.
2.8 DISPLAY
The 3-1/2 digit LED is factory scaled to indicate the space pressurization level in engineering units of either Inches Water Column or Pascals.
2.9 DISPLAY SELECTION
The 3-1/2 digit LED space pressure indicating meter is also utilized for indicating and adjusting the Alarm Setpoint value by depressing a push button switch located under the access door on the cover plate. Pressing of this push button toggles the indicated value between space pressure and alarm setpoint. If the switch is not pressed for approximately 60 seconds the display will automatically defaults to indicate the measured space pressure.
2.10 KEY LOCKED ACCESS DOOR
The Key Locked Access Door allows for controlled access to Guardian configuration, alarm setpoint display and adjustment, alarm delay on activation adjustment, activation/deactivation of the local audible alarm, and differential pressure transducer calibration.

ALARM in the OFF position.
3.5 Analog Space Pressure Output Signal
3.5.1 To provide a 0 to 10vdc analog output signal for remote monitoring of
the space pressurization level place jumper H5/PROCESS in the V position.
3.5.2 To provide a 4 to 20mAdc analog output signal for remote monitoring of
the space pressurization level place jumper H5/PROCESS in the I position.
3.6 Process Output
- Process Output signal can be changed between voltage or current by positioning H5 jumper to I or V. The following table gives the jumper position and corresponding output selection.
