The Halon Bank
Digital Communicator is securely located within the protected premises and
connected to a standard telephone and links the alarm system with a Halon Bank
Alarm Receiving Centre. The connection is made by dialling a dedicated
number and transmitting a high speed coded message. This data provides
specific details of the alarm type/location and identity of the premises.
A communicator has up to eight independent signalling channels with an
additional channel for reporting a test message or a low battery condition.
The transmitted message enables the Alarm Receiving Centre to identify the
type of alarm condition e.g. personal attack, intruder, fire or medical
alert.
Once the message has been clearly displayed at the Alarm Receiving Centre,
an acknowledgement signal is generated to inform the digital communicator
of successful transmission. If the signal is not received at the Halon Bank
Alarm Receiving Centre for any reason the communicator will re-dial the
number.
The presence of the telephone line is monitored continuously, providing an
early indication of line faults on the control unit at the customers
premises. Halon Bank provides a monitoring service covering, a wide
variety of applications including intruder, fire alerts and the
malfunctions of equipment such as refrigeration plants and air
conditioning systems.
