2 Installation
2.1 Installation Preparation
This detector must be installed, commissioned and maintained by a qualified or factory trained
service personnel. The installation must be installed in compliance with all local codes having a
jurisdiction in the area or BS 5839 Part 1 and EN54.
The TX7100 Optical smoke detectors operate on the principle of infra-red light refracting off smoke
particles entering the chambers. This makes detector more sensitive to smouldering fires such as
modern fabric or furnishing. Optical detectors are more prone to false alarm from steam or dusty
environment. For best sensing ability, avoid installing the smoke detector in these areas.
In open air applications as the detectors require ceilings to direct the smoke from the plume
by convection.
On side walls, this will severely delay the response time of a detector and where ceiling
heights exceed 10.5m.
In Rooms where cooking will take place such kitchens, or similar areas where steam and
condensation are present.
Where exhaust fumes are present like car parks.
Where smoke particles will not be produced by fire.
Plant Rooms (unless full discussions regarding the room contents and status subject to a fire
have been made between Client and Manufacturer), Boiler and Generator Rooms.
2.2 Installation and Wiring
1.
Mount the T&A standard base on standard one [1] gang electrical
back box. Do not over-tighten the screws otherwise the base will
twist. Use M4 standard screws.
2.
Connect the wire in terminal as shown in Figure two [2]. Verify the
device number or other device parameters if desired using
handheld programmer then stick on the label before attaching
detector. The sticker labels are available on the control panel.
3.
Attach the detector to the base, point the detector in the base
by the mark-line and secure the detector in that position by
rotating it clockwise, until it reaches the next mark line.
4.
Do not remove the red plastic dust cover until the final handover is
done.
5.
The connecting line of remote indicator should be less than 30
meters.
