5 Securing the Back Box to a Wall
1. There are four screw positions in the rear of the back box for mounting purposes.
Punch the required screw positions or drill using a 4 mm drill.
2. Secure the back box in its mounting position with suitable fixings appropriate to the
mounting surface. Do not over-tighten.
3. There are four cable entry knock-outs on three of the sides and rear face of the back
box. Drill or punch the entries as required.

6 Cable Connections
1. Fit suitable cable glands (included) or conduit fittings to the opened cable entries.
2. Feed the cable through the cable gland.
3. Turn over the detector module and locate the terminal blocks on the back. Remove the
terminal blocks, pulling them toward the center of the module.
4. Connect the cable to the appropriate terminal block, referring to section 2 to 4
depending on the version. Strip and insert the end of each wire into the corresponding
terminal hole, and tighten the terminal screw, using a flat-blade terminal screwdriver
until the wire is secured.
5. Replace the terminal blocks in their correct positions.
7 Ground Connections
Effective grounding is crucial to ensure stable Modbus communications and to limit the effects of radio frequency
interference. Ground points are provided inside the back box. In order to prevent false readings or alarms as a result of
ground loops, ensure that the shield of all cables are grounded at a single point, preferably at the controller.
Consideration should also be given to how conduit, glands and the internal earth plate are also grounded.
NOTE
Any earth regime must avoid earth loops.
8 Securing the Detector Module to the Back Box
1. Remove the front cover from the detector module to expose the retaining screws as
follows:
a) Pull the flap on the bottom side to open it.
b) To unlock the front cover, insert a thin, straight tool, such as a small screwdriver,
into the hole to the right of the tube spigot.
c) While applying slight pressure to the tool, turn the cover counterclockwise until it
stops, and then lift it out.

2. Position the detector module onto the back box ensuring that the Status Indicator is in
the top left-hand corner when viewed from the front.
3. Tighten the four retaining screws using a No. 2 Phillips screwdriver to secure.
4. Where used, tighten the sealing nut of the cable gland to secure the cable. Refer to the
cable gland manufacturer’s instructions.
5. Replace the front cover by placing it into the detector module and rotate it clockwise
until it locks into position.
9 Remote Gassing Connection
If the gas detector is installed in an inaccessible location, such as overhead on a ceiling, connect a tube to the gas
detector for bump test.
• For a temporary connection, open the flap on the bottom side and
connect suitable tubing compatible with the gas type of the sensor to
the tube spigot.
• For a permanent connection, remove the flap, connect the tube
connector (available separately) to the spigot, and then connect a tube
to the tube connector. Secure the tube using a cable tie or small jubilee
clip, taking care not to over-tighten it.
10 Status Indicator
The detector features an external visual status indicator on its front face.
Normal: The indicator is lit GREEN when the concentration of the target gas is within normal range.
The Normal indication can also be set to Confidence Flash
or Off.
Alarm: RED flashes rapidly when the gas concentration is beyond the alarm-level threshold.
Fault: YELLOW
flashes rapidly when the gas detector is in a fault state.
Bluetooth pairing: BLUE flashes when Bluetooth® pairing between the gas detector and a
smartphone is in progress.
Bluetooth connected: Steady BLUE
is lit when a Bluetooth connection is established.
11 Connecting to a Detector via Bluetooth (Bluetooth versions only)
To pair your smartphone with a specific detector, follow these steps:
1. Download Sensepoint App from Google Play Store. Install and launch the app.
2. Create and register a user account, and log on with the created account information.
3. To associate with one or more gas detectors, scan the QR code on the sheet included in the box or enter its
Activation Key.
4. Complete the installation of the detectors.
5. On the app’s home screen, tap DETECTORS to scan for available detectors.
6. Select a detector from the detector list to pair with it.
7. Look for the detector whose Status Indicator is flashing blue.
8. Tap Confirm Detector to pair with that detector. Otherwise, tap Return to list to select one of the others.

When a Bluetooth® connection is established, the detector’s reading is displayed on the app interface with the gas type
and other information.
