1.0 Introduction
The TQ32 Area Alarm Panel enables the group monitoring of commonly used refrigerant
gases such as R410A in areas with air conditioning systems etc. using the TQ31 Refrigerant
sensor. It is designed to monitor a group of sensors in a specific area or floor and give an
indication if any of its sensors have gone into alarm.
The TQ32 Area Alarm Panel will provide a local visual and audible alarm indication when any
of its connected room sensors have entered the alarm state. It can also provide outputs for
remote monitoring, reception or security stations for example as well as providing a plant trip
signal.
There are 32 sensor inputs as standard, expandable to 64 inputs with the addition of an extra
Sensor Input Board. In addition, the TQ32 Area Alarm Panel has 2 optional RS485
communication channels. One channel is for an optional external relay board output that can
provides additional alarm relays if required. The other communication channel is for a
MODBUS Output to provide the status of the Alarm Inputs.

1.1 Indication LED’s and Push Buttons
The LED's on the TQ32 Area Alarm Panel are used to indicate the status of the Unit. There
are three LED’s and a 3 Digit 7-segment LED Display situated on the front of the Panel.
The System Healthy LED is a green LED and should normally be illuminated when power is
applied to the TQ32 Area Alarm Panel. The Refrigerant Alarm LED is a red LED and should
illuminate when an Alarm Input has entered an alarm condition. When the alarm condition has
been removed the Alarm LED will extinguish. The Multiple Alarm LED is a red LED and
should flash when more than one Alarm Input has entered an alarm condition. When the
alarm condition has been removed the Multiple Alarm LED will extinguish.
The 3 Digit 7-segment LED Display is used to show the location (room number) of the alarms.
This will alternate between rooms if more than one alarm is present. See configuration
section for allocating room numbers
3 Push buttons are provided on the front panel. The MUTE button accepts any alarms and
silences the audible alarm. The NEXT button allows the operator to view all rooms that may
be in alarm. The TEST button performs a basic test of the Alarm panel, LED’s and buzzer.
Note. Audible alarms from room sensors will only be silenced when any gas has
cleared and the alarm condition has gone.

address in your internet browser to re-connect to the TQ32 Area Alarm Panel. Make changes
with care or you may permanently lose a connection until the next hardware reset. Clicking
the Back button will take the user back to the Setup Page.
Subnet Mask:
In computer networks, a subnetwork or subnet is a range of logical addresses within the
address space that is assigned to an organisation. The subnet mask is used to inform the
TQ32 Area Alarm Panel that it must send its replies to the gateway if the IP address of the PC
is on a different network. When the subnet mask is set to “0.0.0.0” then it is effectively
disabled and the Default Gateway is not used. A typical subnet mask would be
“255.255.255.0”.
Default Gateway:
A Default Gateway is a node (a router) on a computer network that serves as an access point
to another network. In enterprises, however, the gateway is the computer that routes the
traffic from a PC to the outside network that is serving the web pages. It is only necessary to
configure the default gateway IP address if the PC that is accessing the TQ32 Area Alarm
Panel is on a different network.

Primary/Secondary DNS Server:
The Domain Name System (DNS) is a hierarchical distributed naming system for computers,
services, or any resource connected to the internet or private network. It translates domain
names meaningful to humans into the numerical identifiers associated with networking
equipment for the purpose of locating and addressing these devices worldwide.
Unit Station Number:
The MODBUS ‘slave address’ field usually used on MODBUS Serial Line is used to
communicate via devices on the MODBUS network. This field is a unique address on the
MODBUS network in use.
