General Warnings

WARNING

1. The ZGARD S & DS APOGEE P1
gas sensors described in this
manual must be installed, operated,
and maintained in strict accordance
with the labels, cautions, warnings,
instructions, and within the
limitations stated.

2. The ZGARD S & DS APOGEE P1
gas sensors must not be installed in
outdoor areas or in locations where
explosive concentrations of
combustible gases or vapors might
occur in the atmosphere: Class 1,
Group A, B, C, and D areas as
defined by the NEC. Because the
gas sensors are not explosion­proof, they must be located in non­hazardous areas.

3. Do not paint the ZGARD S & DS
APOGEE P1 gas sensors.

4. The only absolute method to assure
the proper overall operation of a
gas detection instrument is to check
it with a known concentration of the
gas for which it has been calibrated.
Consequently, a calibration check
must be included as part of the
installation and as a routine
inspection of the system.

5. Use only genuine MSA replacement
parts when performing any
maintenance procedures provided
in this manual. Failure to do so may
seriously impair instrument
performance. Repair or alteration of
the ZGARD S & DS APOGEE P1
gas sensors, beyond the scope of
these maintenance instructions or
by anyone other than authorized
MSA service personnel, could
cause the product to fail to perform
as designed, and persons who rely
on this product for their safety could
sustain serious personal injury or
death.

6. The ZGARD S & DS APOGEE P1
gas sensors must be installed,
located and operated in accordance
to all applicable codes. These
codes include, but are not limited to,
the National Fire Prevention Code
and National Electric Code.

7. Do not exceed the relay contact
ratings listed in this manual.
Otherwise, the relay operation may
fail, which can result in personal
injury or death.

Failure to comply with the above warnings

can result in serious personal injury or

death.

ZGARD S & DS APOGEE P1 Gas Sensors

General Information and Applications

The ZGARD S APOGEE P1 sensors are designed to detect the presence of Carbon Monoxide or Nitrogen Dioxide in air.
The EC type employs electrochemical plug-in cells. The solid-state (SS) type employs Metal Oxide Semiconductor (MOS)
sensing technology. Each sensor generates a representative output signal proportional to the calibrated operating range.

The ZGARD DS APOGEE P1 is a Dual Sensor in one enclosure and both sensors employ Electrochemical (EC) plug-in
cells. The sensor is designed to detect the presence of Carbon Monoxide and Nitrogen Dioxide in air.

The ZGARD S & DS APOGEE P1 sensors are specifically designed for the Siemens network communication protocol.
These sensors are integrated with the Siemens equipment and the associated Building Environmental Automation Systems.

The table below provides the distinctive features of the ZGARD S APOGEE P1 Sensors. This is a quick
guide for determining the operating features of each sensor.

The performance of any ZGARD S & DS APOGEE PI sensors are dependent on the appropriate and
strategic placement within a guarded area.

Periodic inspections and calibration: This unit requires calibration. The calibration frequency will be a function of the

operating conditions, including operating under extreme temperatures, exposure to contaminants or gas concentrations
greater than the lower explosive limits. A calibration inspection must be included as part of a routine maintenance to
ensure proper operation of the gas detection unit. If unit span or zero cannot be adjusted, the sensor may be approaching
its end-of-life or has been contaminated and must be replaced.

ZGARD S & DS APOGEE P1 Sensors
Installation Guidelines

Mounting:

• Do not mount the sensor to structures subject to vibration and shock, such as piping and piping

supports.

• Do not locate the sensor near excessive heat source or in wet and damp locations.

• For proper cooling, allow at least five inches of clearance around all surfaces except for the mounting

surface. Also consider mounting the sensor so it can be easily accessed for service and routine testing.

• The sensor has four mounting lugs; securely mount the instrument to a wall or support using

appropriate hardware.

Wiring Connections:

Before putting a ZGARD S & DS APOGEE P1 sensor into operation, determine the elevation and the number of
gas sensors according to the required application. Also refer to the ZGARD S & DS APOGEE P1 sensor

Installation Outline drawings 107130 and 107139 located in the back of this manual, which provides
important information regarding;

• Required conductors and wire size: Connect an electrical cable between the devices.

• Operating power: The 24Vac operating power is connected on terminal TB1.

• APOGEE P1 Network wiring connection: The connection terminal labeled + and - are for

communication. Install a ground shielded cable on terminal marked S.

CAUTION

1. When wiring the sensor, disconnect the main power to prevent bodily harm.

2. Do not use the sensor power when connecting any external devices.

3. Use shielded cable for wiring installation. Do not install low voltage signal cable in the same conduit as

the other devices such as sensors operating power and or relay wiring.

4. When connecting the remote sensors, make sure that all wiring is correct for the power and signal

leads. Make sure that all wiring is correct and the two connecting leads of the digital output are not

interchanged or permanent damage to the sensor may result.

5. Perform all wiring and conduit installation in accordance to the National Electrical Code.

Failure to follow the above cautions can result in injury or property damage.
