SAFETY WARNINGS
FOR SAFETY REASONS, THE TQ32 AREA ALARM PANEL MUST BE
INSTALLED, OPERATED AND SERVICED BY QUALIFIED PERSONNEL ONLY.
READ AND UNDERSTAND THIS INSTRUCTION MANUAL COMPLETELY BEFORE
OPERATING THE TQ32.
THE OPERATION DESCRIBED IN THIS DOCUMENT IS THE INTENDED USE OF
THE TQ32.
TQ ENVIRONMENTAL LIMITED CANNOT BE HELD RESPONSIBLE IF THE TQ32
IS USED FOR ANY PURPOSE OTHER THAN THAT STATED. ANY OTHER USE OF
THE TQ32 WILL INVALIDATE ANY CERTIFICATES ISSUED.

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.

Each TQ32 Alarm panel needs to be securely wall mounted, ideally in a central location. The
TQ32 alarm panel will need to be connected to the mains supply.
Each room being monitored will need a TQ31 Refrigerant Room sensor fitted. These can be
mounted to 50mm deep, double back boxes and connected to the mains supply. See TQ31
manual for further instruction. A 2 core, 0.5 mm2 cable to signal any alarm condition needs to
be run back to the TQ32 Alarm panel from each room sensor.
If an optional Reception indicator panel is used to identify which floor or area is in alarm, then
a 3 core 0.5 mm2 cable needs to be run from the alarm panel relays to the reception panel.

2.1 Power Connection
WARNING 240VAC
Power for the TQ32 Area Alarm Panel is from a 100V-240V 50/60Hz AC supply. The green
power LED will illuminate on the front panel.
The power connection is via a fused terminal located
at the bottom right hand side, inside the alarm panel enclosure.
2.1 Sensor Connections
Each room sensor needs to be connected to the TQ32 Alarm Panel with a 2 core cable as
shown below. The input board terminals will accept wire sizes up to 0.5mm2.
Sensor inputs are connected in vertical pairs left to
right along the TQ32 input boards, as shown.
32 inputs on the top board with an additional 32 input
available from the lower board if fitted.
Each sensor pair should be connected to the TQ31
room sensors Common (C) and Normally Open (NO)
alarm contacts. See TQ31 manual for further
identification.

2.3 Relay Connections
Five Common Alarm Relay contacts are available for remote indication on Connectors
CONN14 to CONN18.
(Normally Closed) contact is on Pin 1, (Common) contact is on Pin 2, and (Normally Open)
contact is on Pin 3.
The five relays can be typically used for:
1 x Fault
2 x Refrigerant Alarm - Plant Trip
2 x Refrigerant Alarm - Reception/Control Room
These contacts operate on the alarm state of the Alarm Panel’s inputs (TQ31 room sensors)
and are configurable via the internal web-server. These can be left as common relays
(default) or each of the 4 alarm relays can be allocated a group of sensors to further split the
alarms if required.
For each alarm relay RL1 (Fault)
plus RL2, 3, 4 & 5.
2 sets of output contacts are
available.
Each set of outputs has Common,
Normally Open and Normally Closed
volt free contact available as shown.
