JTG-HM-FDF241 Infrared Flame Detectors

Product Manual

Overview

The flame detector measures infrared radiation and can therefore detect organic mate-

rial fires with and without smoke.

The table below shows what types of fire the flame detector can and cannot detect.

Detection No detection

Liquid fires without smoke -

Gas fires without smoke -

Open organic material fires with smoke,

for example fires of:

l Wood

l Synthetic material

l Gas

l Oil-based products

Inorganic materials, such as:

l Hydrogen

l Phosphorus

l Sodium

l Magnesium

l Sulfur

However, if inorganic materials are burning in a fire with organic materials, e.g. packag-

ing material, the flame detector can detect the fire.

Thanks to extended sensory technology, JTG-HM-FDF241 is not susceptible to decep-

tive phenomena (e.g. the sun) and can therefore also be used in outdoor areas.

Characteristics

– Fulfill Chinese standard GB15631-2008 “Special type fire detector“

– ASA JTG-HM-FDF241 flame detector for the most demanding application (inside and

outside), detection with 3 infrared sensors and ASAtechnology

Structure The flame detector consists of the base FDFB291 (1) and the flame detector FDF241CN (2). 1 2 1 Base for flame detector 2 Flame detector Accessory: A mounting bracket and ball and socket joint are available to aid flame detector installation at a particular angle. A rain hood is available to protect against rain. All dimensions in mm.

Install base FDFB291 for flame detector JTG-HMFDF241 (Fig. 1) Danger of fall! Always use a secured ladder or lifting platform for the mounting work! 1. Break open the plastic parts in the base for flame detector at the openings you require for cable entry (1). If necessary screw the M20 x 1.5 metal cable gland into the openings. 2. Use four screws (2) to fit the base for flame detector on the mounting bracket, ball and socket joint, rain hood or directly on a stable, vibration-free surface.

Performance check with a test fire 1. 2. 3. On the control panel, switch off the remote transmission of alarms. To do this set the 'Detector test' operating mode on the control panel. Use a test fire to test the flame detector. ð The flame detector activates an alarm within 20 seconds. ð The alarm indicator on the flame detector flashes. On the control panel, switch the remote transmission of alarms back on. ð The flame detector is ready.
