MOUNTING AND WIRING
Removal of cover
The top cover can be removed by inserting a screwdriver blade into the 6 slots at the top of the
unit, and levering the plastic outwards to release the 6 clips.
Regular access to the inside of the unit should not be required, although occasional access
may be required to access the SIM card, or to add a daughter board for additional facilities.
(i.e. dial capture board).
The unit supports all BT Redcare enabled SIM types. (BT Redcare O2 / BT Redcare BT
mobile / BT Redcare Roaming). The SIM type is auto detected by the unit without need for any
configuration change.
Mounting
The unit should be mounted inside the alarm panel, or inside a separate powered housing,
using the sticky mounting pads supplied.
The back of the unit also supports DIN rail mounting for housings that support this type.
The supplied aerial should be mounted on top of the outside of the housing by removing the
adhesive backing.
