3.8 Fire Alarm Ratings
The following model is approved for use as an audible signal
appliance for fire alarm use – public mode (UL464) and
produces a sound pressure level above 75dB(A) at 10 feet:

For Fire Alarm applications, the Sounder Volume must be at
the highest setting, (see volume control section).
For fire alarm use, the temporal pattern tone No. 12 as per the
tone table provided in these instructions must be selected. This
tone produces a minimum sound pressure level of:
CAN/ULC-S525: 100.4dB(A)* at 10 feet.

4) Special Conditions for Safe Use
Special Condition for safe Use as stated on the Type
Examination Certificate DEMKO 14 ATEX 4786493904X / CoC
IECEx ULD 14.0004X:
End user shall adhere to the manufacturer’s installation and
instruction when performing housekeeping to avoid the
potential for hazardous electrostatic charger during cleaning,
by using a damp cloth.
The D2xS1 is not to be mounted with the horn facing upwards
The equipment shall only be used in end use with appropriately
certified cable entry devices and blanking plugs
4.1 Installation
The product must only be installed by suitably qualified
personnel in accordance with the latest issues of the relevant
standards.
The installation of the units must also be in accordance with
any local codes that may apply and should only be carried out
by a competent electrical engineer who has the necessary
training.
The alarm horn is not to be mounted with the horn facing
upwards.
The equipment has not been assessed as a safety-related
device (as referred to by Directive 94/9/EC Annex II, clause
1.5).
The cable entry temperature may exceed +70ºC / the cable
branching point may exceed 80ºC. Therefore suitable heat
resisting cables and cable glands must be used, with a rated
service temperature of at least 90ºC.
To maintain the ingress protection rating and mode of
protection, the M20 x 1.5 cable entries must be fitted with
suitably rated, certified cable glands and/or suitably rated,
certified blanking devices during installation. If a high IP
(Ingress Protection) rating is required then a suitable sealing
washer must be fitted under the cable gland. For use in
explosive gas atmospheres a minimum ingress protection
rating of IP54 must be maintained. For use in explosive dust
atmospheres a minimum ingress protection rating of IP64 must
be maintained.
