INSTALLATION
Planning
This gas detection and ventilation control system is designed for installation into car parking
facilities and enclosed garages in the United States of America.
It is designed to be paired with AGS Nitrogen (NO2) and Carbon Monoxide (CO) gas detectors
that will be linked via MODBUS back to this Parksafe control panel. The Parksafe control panel
will monitor the connected detectors in numbers up to 16 per panel.
The Parksafe will make or break a dry contact internally on Alarm 1 and a second contact on
Alarm 2. This is to have a live feed to the ventilation system wired through the contact so that on
alarm, the Parksafe can activate the fans. This can either be via a direct live to the fan or via a
run signal. There is a second relay for Alarm 2 that will activate after alarm 2 has been activated
for an extended period of time. This can be used for a link to the BMS or other external indication
device. The Parksafe also has the 0-10VDC output to allow the panel to drive VSD’s based on
the gas detector outputs.
The Parksafe is designed to be located in an office or area within the carpark not accessible to
the public.
Generally, the installation height of a sensor for Nitrogen Dioxide would be close to the ground,
and for Carbon monoxide gases, sensors would be positioned at a higher point in the area. Any
recommended heights may vary based on air flow and temperature conditions in addition to
the proposed application and location.
Carbon Monoxide (CO) gas Breathing Zone - 1700mm (5ft 6”) from ground level.
Nitrogen Dioxide (NO2)gas Low Level - 300mm (1ft) from ground level.
Typical Installation Arrangement
Placing the Parksafe panel at eye level allows for optimum monitoring of the display screen.
Please refer to your detector manual for important information regarding coverage, location
and positioning including areas and conditions to avoid.

Up to 16 detectors can be connected to the Parksafe panel and chained up to approx. 500
yards from the panel (this varies depending on chain configuration, wire type and condition).
For more information refer to your AGS Parksafe detector manual.
4. SOUNDER/ STROBE
This relay output (24V) is for an external sounder alarm/ strobe lighting to activate on alarm.
5. 24VDC
This is a permanent 24V DC power output for external auxiliary devices.
Max output: 200mA.
6. 0-10V OUTPUT
This output can drive ventilation systems. The 0-10V output will send 5V when Output 1 relay is
activated and 10V when Output 2 relay is activated.
Under normal conditions, the output can be 0 or 2V –selectable in the settings menu.

Parksafe Detector Identification
When wiring multiple detectors to the Parksafe panel it is important to identify each detector
and in which monitoring zone the detector is located for the Park Safe system to receive and
display data. Detector ID switches are fitted to detector circuit boards.
For more information refer to your Parksafe detector manual.
Detector Chain Termination Resistor Switch
Signal communication issues may occur where the bus length is too long or
high baud rates are used. In this instance –terminating at each end of the
chain may help the quality of the data signal. To do this - turn on the
[CHAIN TERMINATION RESISTOR] switch.
For more information refer to your Parksafe detector manual.
Settings Switch
On the front display circuit board you’ll find a SETTINGS
switch –when switched to ON, the screen will display
the settings menu –you can now configure your
Parksafe system.
When changes have been made –turn the SETTINGS
switch off and the system will automatically restart.
Settings Menu
The Parksafe panel has a touch screen which allows the engineer/ user to configure the system.
Adjust the screen brightness. Change/select option.
(Press or slide the cursor up and down) (Press the blue option box or press and hold)

OPERATION
First Power Up
On connecting mains power, the Parksafe control panel will
‘warm up’ for approximately 60 seconds –during this time the
screen will display an ‘system initialising’ message.
The panel will now search for detector signals.
Home Screen & Alarm Condition
When the Parksafe system has completed initialising, the home screen will display an overview of
each relay output and system condition.
System OK.
Under normal/ safe condition, all output indications remain green.
System in ‘Pre-Alarm’ condition.
When gas values detected reach pre-alarm levels - ‘OUTPUT 1’relay will activate and 5V will be
sent to a ventilation system in order to clear and maintain a safe quality of air.
Other relays (Damper) and external devices may activate if configured –see settings menu.
System in ‘Alarm’ condition.
When gas values detected reach alarm levels - ‘OUTPUT 2’ relay will switch and 10V will be sent
to a ventilation system. If the gas levels do not clear after a period of time (selectable in the
settings menu) the Parksafe systems ‘ALARM’ relay will activate and the Parksafe panel will enter
the Alarm condition. The internal buzzer will sound to alert the user that dangerous gas levels are
present.
To silence the internal buzzer –press the ‘SILENCE’ button on the front panel. This will
also silence any external audio sounders connected.
If the Parksafe system reaches Alarm condition –the control panel will need to be
reset when the gas values return to a safe level.
Check the detector information pages to identify where gas has been detected
and if levels are returning to a safe condition before resetting the system.

Fault Status
You should contact your supplier immediately if FAULT appears as a detector status. This
message indicates an issue with the gas sensing module within the gas detector device.
Locate a Parksafe detector by matching the unique serial/ ID number.
End Of Life Status
This message indicates that the Parksafe detector has reached its expected operational
lifecycle. No gas levels will be displayed. Contact your supplier immediately.
The expected lifecycle will depend on the type of gas your detector is targeting and may vary
depending on environmental conditions.
For more information refer to your Parksafe detector manual.
Service Status
It is important to maintain the gas sensing elements of external detectors for optimum
performance and security of the system.
When detector status displays the ‘SERVICE’ message contact your supplier immediately.
Parksafe detectors will still operate as intended but its sensitivity can be inhibited by external
factors such as, dust; humidity; temperature fluctuations; cleaning products; contaminants or
sensor drift (ageing). All can cause a decline in sensitivity and eventual failure.
It is recommended that Parksafe detectors are inspected and serviced at least annually from
the date of installation for optimum performance and protection.
Contact your supplier for more information.
General Maintenance
DO carefully remove any accumulated dust from outer enclosures once a month.
NEVER use detergents or solvents to clean your devices –this may permenantly or temporarily
damage the gas sensing elements.
NEVER spray lighter gas, paint or other aerosols near your devices.
NEVER paint devices. Paint will seal vents and may cause interference.
Avoid exposure of high concentrations of alcohol found in many products, this can damage,
deteriorate or affect the gas sensing elements. For more information refer to your Parksafe gas
detector manual.
