WARNINGS
Touchpoint 1 is designed for installation and use in indoor safe area
non-explosive atmospheres. Installation must be in accordance
with the recognized standards of the
appropriate authority in the country concerned.
Before carrying out any work ensure local regulations and site procedures
are followed.
Access to the interior of the controller, when carrying out any work, must only be
conducted by trained personnel. Switch off and isolate the power supply
to the controller, or obtain a hot work permit, when access is required. Take any
necessary precautions to prevent false alarms.
The detectors/sensors that the controller connects to may be used for gas
detection in hazardous atmospheres. Refer to the individual detector/sensor
instructions for their details.
Caution When carrying out any work ensure that executive outputs from the
controller are inhibited in order to prevent false alarms.
This chapter provides the following information about installing Touchpoint 1:
• where to locate the controller, its dimensions and how to mount it
• how to access the interior of the controller, see page 12
• cabling and wiring, see page 13 and page 14
Note It is recommended that a local fused power feed spur, with lockout switch, is used.
Earth/Ground loops or poor screening are the most common cause of false alarms.
Proper installation, using appropriate earth techniques improves:
• resistance to radio frequency interference (RFI), e.g. mobile phones and walkie-talkies
• resistance to induced signals from magnetic fields (EMC), e.g. high power cables
and switch gear.
Location
Touchpoint 1 can only be installed in indoor safe areas.
Refer to International codes of practice, e.g. National Electrical Code (NEC) or Canadian
Electrical Code (CEC), where applicable, for guidance when installing.
Ensure that the maximum distance from the controller to the detector is within specification.
Locate the bracket so that when the controller is fitted to it there is:
• easy access to it
• a clear view of the controller‘s display (normally eye level), check for national/
local regulations regarding the viewing of displays

• enough space to open the enclosure’s access panels, for cabling, maintenance,
adjustments, etc.
• enough space for cable or conduit access to the bottom of the enclosure
Follow the advice of:
• experts having specialist knowledge of gas detection and control systems
• experts having knowledge of the process plant system and equipment involved
• safety and engineering personnel
Always record the location of the detector that is connected to the controller.

Mounting
Touchpoint 1 is supplied with a mounting bracket that fits onto a suitable wall. The controller is then
hooked onto the bracket. The previous diagrams show dimensions for
Touchpoint 1 and the bracket.
Fit the bracket to a flat, firm surface, e.g. wall, suitable for the controller’s size and weight.
Recommended screw for mounting is M3.5 x 25 (or #8 x 1").
1 Mark out and drill 4x M3 holes for the mounting bracket fixing screws.
Use the mounting bracket as a template for the position of the holes.
2 Fix the bracket securely to the wall.
Use appropriate fixings for the surface to which the bracket/controller is mounted.
3 With the bracket secure, locate and then lower Touchpoint 1 onto it.
Ensure both top and bottom hooks on the back of the unit engage properly in the mounting
bracket slots.

Controller Components
This procedure describes how to access the components inside the controller.
1 Loosen the single captive screw securing the Terminal Module access panel.
The panel is located at the bottom of the enclosure.
2 Push down on the finger grips at the top of the access panel.
3 Slide the panel down to release it.
4 Pull the panel outward.
Pull it until the door is approximately at a right-angle to the enclosure.
5 Push the panel inward toward the enclosure.
This locks it in the open position and provides two handed access to the cable entries, etc.
