10	Exhaust outlet
11	Gas cylinder
12	Demand flow regulator
13	Calibration gas hose

Warning

The atmosphere must be free of background gas. Do not use the base station in a hazardous area.

All required National Electrical Codes (NEC) and safety standards must be followed.

Note

The base station can operate from either an electrical power source or batteries. The batteries will provide automatic backup power if the main power fails.

1. Connect the power cord to the POWER port on the base station and then plug the cord into an AC outlet.
To install the batteries, refer to Battery Installation

2. Connect the charger cord to the CHARGER port on the base station and then plug the cord into an AC outlet (if applicable).

3. Attach all gas connections. Inlet 1 (PURGE) is configured for ambient air and inlets 2-5 are configured for calibration/test gases. Refer to Confirming Inlet Setup.

4. Connect the demand flow regulator. A demand flow regulator must be used with all gas cylinder connections.

5. Ensure the exhaust line is not connected to a negative pressure system.

For AC main installation, a circuit breaker must be integrated in the building installation as a disconnect device for the base station.
The disconnect device must be installed in close proximity to the base station and must be marked as a disconnecting method for the base station.

Battery Installation

Warning

Only change batteries in an atmosphere that is free of hazardous gas. Failure to adhere to this warning can result in personal injury and/or property damage.

To install batteries in the base station, refer to Figure 4. and complete the following:

1. Loosen the retaining screws from the battery cover. Do not remove the retaining screws from the battery cover.
2. Remove the battery cover.
3. Insert four C-cell batteries into the battery compartment.
4. Replace the battery cover and tighten the retaining screws. Do not over tighten the screws. Refer to Table 12.

Inserting the GasAlertClip Extreme and the GasAlert Extreme

Caution

Infrared or intense ambient light (sun or halogen) may interfere with the base station/detector communication.

Figure 5. Inserting the GasAlertClip Extreme and the GasAlert Extreme

Table 7. Inserting the GasAlertClip Extreme and the GasAlert Extreme

Item	Description
1	Alligator clip
2	Docking module lid
3	Release tabs
4	Detector bay

1. Activate the detector and wait until it is in normal operation.
2. Ensure the alligator clip is closed and the ring is resting flat to prevent disruptions with the data transmission.
3. Press the two release tabs on the docking module and raise the lid.
4. Lower the detector (serial number up) into the detector bay. Push forward to ensure the top of the detector connects with the top of the bay.
5. Lower the lid and press down until the release tabs click.

When the detector has been inserted correctly, the RUN LED(s) on the docking module lights yellow and the base station LCD displays the

• the docking module number,
• Unit Inserted,
• detector type, and
• detector serial number.

6. To bypass the base station identification screen, press any button on the base station.

Inserting the GasAlertMicro

Caution

Infrared or intense ambient light (sun or halogen) may interfere with the base station/detector communication.

Item	Description
1	Docking module lid
2	Release tabs
3	Detector bay
4	Charge status indicator (charging model only)
5	Connector pins (charging model only)
6	Alligator clip

1. Activate the detector and wait until it is in normal operation.
2. Ensure the alligator clip is closed and the ring is resting flat on the detector to prevent disruptions with data transmission.
3. Press the two release tabs on the docking module and raise the lid.
4. Insert the bottom of the detector into the detector bay (serial number up) and then lower the top into place.
5. Lower the lid and press down until the release tabs click. When the detector has been inserted correctly, the RUN LED(s) on the docking module lights yellow and the base station LCD displays the

• the docking module number,
• Unit Inserted,
• detector type, and
• detector serial number.

Inserting the GasAlertMicro 5/PID/IR

Note

The GasAlertMicro 5, GasAlertMicro 5 PID, and GasAlertMicro 5 IR are referenced as the GasAlertMicro 5/PID/IR.

Caution

Infrared or intense ambient light (sun or halogen) may interfere with the base station/detector communication.

Figure 7. Inserting the GasAlertMicro 5/PID/IR

Note

Table 9 references Figure 7 and Figure 8.

Table 9. Inserting the GasAlertMicro 5/PID/IR

Item	Description
1	Docking module lid
2	Release tabs
3	Diffusion adapter
4	Detector bay
5	Connector pins (charging model only)
6	Charge status indicator (charging model only)
7	Connector outlets
8	Diffusion adapter release tab
9	Tool used to push down on diffusion adapter release tab

1. Activate the detector and wait until it is in normal operation.
2. Ensure the alligator clip is closed and the ring is resting flat on the detector to prevent disruptions with data transmission.
3. Press the two release tabs on the docking module and raise the lid.

Important: If the GasAlertMicro 5/PID/IR detector is fitted with a pump, the diffusion adapter must be removed from the docking module lid.
