REFLECTOR PANEL HEATER INSTALLATION GUIDE Issue 5 May 2007 2104M0728
1 Introduction
The Reflector Panel Heater is designed to be used with the Searchline Excel Cross Duct
infrared gas detector (see manual 2104M0511 for further details of this system). The
Reflector Heater Panel replaces the standard double glazed retro-reflector in applications
where there is risk of condensation occurring on the retro-reflector. The Reflector Heater
Panel is available in two sizes: short range (part number 2104B0715) and long range (part
number 2104B0716).
2 Safety
Ensure that you read and understand these instructions BEFORE handling or operating the
equipment.
Please pay particular attention to the Safety Warnings.
WARNINGS
The Reflector Panel Heater is certified for and intended for use in potentially hazardous areas.
Install and use the Reflector Panel Heater in accordance with the latest regulations.
For installations in the UK, the code of practice SELECTION, INSTALLATIONS AND
MAINTENANCE OF ELECTRICAL APPARATUS FOR USE IN POTENTIALLY EXPLOSIVE
ATMOSPHERES should be strictly observed. General recommendations are given in
BS5345:Part 1:1989. Specific requirements for flameproof (Type ‘d’), Intrinsically safe (Type ‘i’)
and increased safety (Type ‘e’) protection are given in BS 535: Part 3: 1979, BS 5345:Part 4:1977
and BS 5345: Part 6:1978 respectively.
For installations in North America, the national electrical code (NFPA 70 -1990) or later issues
should be strictly observed.
Elsewhere, the appropriate local or national regulations should be used.
The code of practice regarding SELECTION, INSTALLATION, USE AND MAINTENANCE OR
APPARATUS FOR THE DETECTION OF COMBUSTIBLE GASES (OTHER THAN FOR MINING
APPLICATIONS OR EXPLOSIVE PROCESSING AND MANUFACTURE) must be complied with.
Refer to BS6959:1988 in the UK o the appropriate local or national regulations.

3 Certification
The certification details and special conditions for use are shown below.
The Special Conditions for Safe Use are as follows:-
1. The integral supply cables must be mechanically protected and terminated in a
suitable terminal or junction facility.
2. In addition to the integral earth conductor, earth equipotential bonding may be
maintained via the rear mounting thread.

5 Installation
The Reflector Panel Heaters are designed to allow installation to be performed by a single
operator. The installation procedure is split into mechanical installation and electrical
installation.
5.1 Mechanical Installation
Follow these instructions carefully. Do not attempt to dismantle the Reflector Panel Heater in
any way.
5.1.1 Replacement of standard retro-reflector panels
If the Reflector Panel Heater is replacing a standard retro-reflector panel then the existing
duct cut out and mounting holes can be re used.
1. Ensure the system is switched off.
2. Loosen the 4 screws that clamp the retro-reflector assembly in position.
3. Lift the assembly up and outwards to release it from behind the screw heads.
4. Slot the Reflector Panel Heater assembly over the 4 screw heads and allow its
weight to be supported on the exposed sections of the thread.
5. Tighten the 4 screws to clamp the Reflector Panel Heater assembly in position.
5.1.2 Installation of Reflector Panel Heaters
If installing the Reflector Panel Heater to a new duct location follow the procedure below:
1. Stick the retro-reflector cut-out template to the outside of the duct wall opposite
the transmitter/receiver, ensuring that point X* is directly opposite point X on the
other template. (This will ensure that the transmitter’s IR beam hits the centre of
the retro-reflector).
2. Drill 6 mounting holes (7mm diameter) in the positions marked J on the template.
3. Following outline K, cut a square aperture in the duct wall.
4. Insert the two retro-reflector panel support bars through the aperture and attach
them to the inside of the duct using M6 washers and nuts. Ensure that the
threaded holes in the support bars line up with the holes drilled in the duct.
5. Fit four M6 x 16 cap head screws into the holes in the support strips but do not
tighten. Leave approximately 5mm of thread exposed on the outside of the duct.
6. Slot the retro-reflector assembly over the heads of the screws and allow its
weight to be supported on the exposed sections of thread. Tighten the four
screws to clamp the retro-reflector assembly in position.
