SmartTerminal
SmartTerminal
connects to the
LoopSense
Fire Alarm Control Panel (FACP) via the RS485
multidrop communication port. Generally it is designed to be used anywhere where the status of the
FACP is required to be monitored by local personnel and limited control is required.
SmartTerminal;
Includes front panel controls that allow the resetting of alarms and activation/silencing of
alarm devices. Enabling operational access to the controls is via a key-switch;
Reports events from devices that are accessible to the host FACP. For example if the host
FACP is configured with global access then the connected SmartTerminal reports events
from all devices. If the host FACP is configured as local then the connected SmartTerminal
reports events from devices that are directly connected to the host FACP.
10.6.1 Operation
The operation of
SmartTerminal
can be considered to be in one of three states, these are;
1. Power up - when the
SmartTerminal
is initialising
2. Normal - when the
SmartTerminal
address has been set and is communicating with the
FACP, reporting normal / abnormal conditions and controlling the FACP via the front panel
controls
3. Fault where the
SmartTerminal
is in fault and/or is unable to communicate with the FACP.
10.6.2 Power Up
The LCD displays a message telling the operator
SmartTerminal
is being powered up and that the
hardware is being initialized. Once the hardware has been successfully initialized set the address
and
SmartTerminal
should automatically transition to the normal state. Should a failure occur on
power up press the “RESET” button located on the LCD PCB and check the address is correct.
10.6.3 Access levels
There are two levels of access.
Access level 1
only the silence buzzer, previous, next and override front panel controls are
operative. All other controls operate in access level 2.
Access level 2
is entered when the key-switch is in the ENABLED position.

10.6.4 Overview
SmartTerminal
essentially consists of two PCBs;
BRD82LTB
– Termination Board
A Termination Board is mounted in each SmartTerminal to protect and interface the RS485
communications and 27VDC supply to the LCD Board
BRD82ICC
– Control, LCD Communications and LCD Driver Board
Note:
A maximum of 30
SmartTerminal
’s
may be connected to the communications bus over a
distance of approximately 1.2Kms
