•
All metal castings are of LM6 aluminium alloy, corrosion resistant, anodised and outside surfaces
finished with a polyester paint coating.
•
The strobe dome is of clear borosilicate glass.
•
The
sound-shaping
components are of flame retardant ABS.
•
The coloured lens is of flame retardant polycarbonate.
•
All external fasteners are of stainless steel.
•
All sounders have 32 sound signal selections. From the 32 sound signals, any signal may be chosen
as the first stage alarm and any signal for the second stage alarm.
•
Sound output level and current consumption depends upon the signal selected. Typical sound output
level at 1 metre is 110dB(A) and typical current consumption is 350 mA for 24VDC, 110 mA for 115
VAC and 55 mA for 230 VAC depending upon sound signal selected. These values apply for Gas
Group IIB; for Gas Group IIB+H2, sound output is reduced by typically 3dB.
•
All strobes have a xenon flash rate of 1Hz, one flash per second. The flash energy is 5 joules with a
typical current consumption of 220 mA for 24VDC, 135mA for 48VDC, 90 mA for 115 VAC and 45 mA
for 230 VAC.

WARNING: POSSIBLE ELECTROSTATIC RISK
The Horn and Lens may become electro-statically charged and should not be touched or rubbed when in
operational service. If cleaning is required follow the warning given on the equipment label and clean only
with a suitable damp cloth.
THREADED CABLE ENTRIES
All threaded cable entries to be fitted with an ATEX certified component and the thread sealed with a suitable
non-setting thread sealant to maintain IP66 rating.
SPECIAL CONDITIONS FOR SAFE USE (BASEEFA CERTIFIED)
•
The equipment incorporates flameproof joints which have a maximum gap less than that
stated in the standard EN50018:2000 to which it is certified.
(Note: EN60079-1 replaces EN50018)
The user must ensure that the diametric clearance associated with the spigot joint at
each end cover does not exceed 0.064mm and the gap between the face of each end
cover and the body does not exceeed 0.038mm.
•
For replacement purposes the end cover fixing screws shall be of minimum grade A4-80
stainless steel.
•
The cable entry device shall be suitably sealed to maintain IP66 rating.
