Mounting and wiring
Removal of cover
The top cover can be removed by gently
releasing each of the 4 clips on the base
of the unit by pushing the clips outward
with a screwdriver blade.
Regular access to the inside of the
unit should not be required, although
occasional access may be required to
access the SIM cards.
Mounting
The unit should be mounted inside a
suitable robust enclosure, using the
sticky mounting pads supplied.
For security installations the
enclosure must meet or exceed
the protection requirements of the
particular security grade for the whole
installation as per EN 50131-1.
For fire alarms it is recommended
the signalling unit is mounted within an
enclosure separate from the fire alarm
panel or fire alarm power supply.
For all installations access to the
unit needs to meet EN50131-1 installer
access level 3.

MOUNTING AND WIRING
Caution: mounting the signalling
unit within fire alarm panel or fire
alarm power supply enclosure might
invalidate their compliance with EMC
regulatory requirements.
The separate enclosure must meet
the requirements of EN 54-2 and EN
54-21 associated with access restriction
to installer level 3, ingress protection
to IP30 or above and power supply
integrity. The transmission of fire alarm
signals and the state of the fault and
acknowledge outputs on the signalling
unit shall be displayed at the separate
enclosure or at the fire alarm panel.
If the fire panel and the separate
enclosure are some distance apart
(i.e. not within line of sight) then the
indications should be at the panel.
For optimum performance the
supplied aerial should be mounted
vertically outside of and away from,
the housing by removing the adhesive
backing. Ideally the aerial should not
be mounted on a metal surface. The
aerial should be installed a distance of
20cm or greater away from any user or
bystander.
