Product Description
Figure 1 – Essential unit (not to scale)
The BT Redcare Essential unit is a wireless single path, roaming SIM, alarm signalling unit for transmitting alarm signals
from a customer’s alarm panel, via the BT Redcare network to an Alarm Receiving Centre (ARC). The Essential unit has a
UK roaming SIM with 4G/2G mobile technology. The unit is designed for use in security systems only.
The unit communicates via the BT Redcare Network and a valid TA account must exist for the unit to communicate. The
TA account will have been populated with the serial number of the unit.
The unit has 8 general purpose alarm inputs, and 2 outputs, making it suitable for connection to most common alarm
panels.
The unit is supplied already fitted with a BT Redcare enabled SIM card.

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 card.
Mounting
The unit should be mounted inside the alarm panel, or inside a separate powered housing, using the sticky mounting pads
supplied.
The enclosure must meet or exceed the protection requirements of the particular security grade for the whole installation
as per EN 50131-1.
The supplied aerial should be mounted vertically outside of the housing by removing the adhesive backing.

Connection Terminals
The screw terminals for the alarm inputs are suitable for use with a standard 3mm blade terminal screwdriver.
Power connections
Power to the unit is via 2 screw terminals at the centre, with positive to the right nearest Pin 5.
The supply voltage range is 9V to 30V. The unit is designed to be connected to the Auxiliary power output on an
associated alarm panel, or separate powered enclosure. For use with intruder alarm panels the power supply must meet
the requirements of EN 50131-6.
Ensure the power source is sufficient to power all devices connected. See the power requirements in the specification
section. The account at the Alarm Receiving Centre (ARC) should be put “on test” before power up, as signals will be sent
following initialisation.
Alarm inputs
The unit has 8 alarm inputs which are presented on screw terminals along the bottom of the unit. These are labelled as
Pin 1-4 and 5 -8.
By default the 8 alarm inputs require a positive condition to be presented to send an alarm. (Default = Positive applied).
This can be changed using the Pin Learn button or through the configuration menu. See later section on configuration.

Outputs
Two relay outputs are provided on screw terminals at the top of the unit.
Output 1 is Comms, output 2 is Func.
See the further sections on outputs for a full explanation.
Serial data connections
The serial data connection labelled TX, RX, B and A is configurable for RS485 or RS232 connection depending on the
panel.
This is done in the configuration menu.
These ports allow serial alarm panel connection, see the Panel Upload Download section.
Dial capture
The dial capture (Dial Cap) terminals enable interfacing with an alarm panel’s digital communicator. The alarm panel can
then send SIA, CID or Fast Format messages through the unit to the Alarm Receiving Centre.
Dial capture can also be used for upload download UDL, allowing remote access with some types of alarm panel.
Aerial connection
Connect the supplied aerial to the MMCX connector on the top right of the unit. The aerial should be placed in a vertical
position that receives the best wireless coverage. Carry out a survey to establish the best location.
If necessary, a selection of high gain and extension aerials can be purchased from the BT Redcare shop at
