INSTALLATION
Planning
The Parksafe control panel is designed for installation into car parking facilities and enclosed
garages. It is designed to be paired with AGS Parksafe Gas Detectors (Nitrogen Dioxide and
Carbon Monoxide) that will be linked via MODBUS back to the control panel and monitor the
connected detectors in numbers up to 16 (per control panel) and automatically control ventilation
systems according to gas levels and an optional temperature level.
The Parksafe will make or break a dry contact internally on OUTPUT 1 and a second contact on
OUTPUT 2. This is to have a live feed to the ventilation system wired through the contact so that the
Parksafe can activate ventilation/ fans, this can either be via a direct live feed or via a run signal.
There is another output relay that will activate after OUTPUT 2 has been activated for an optional
extended period of time. This can be used for a link to the BMS or other external indication device.
The Parksafe also has a 0-10VDC output to allow the panel to drive VSD’s based on gas level
outputs. The Parksafe control panel is designed to be located in an office or other suitable area
within a carpark not accessible to the public.
Please refer to your detector manual for important information regarding coverage, location and
positioning including areas and conditions to avoid!
Typical Installation Arrangement
Place the control panel in accordance with regulations ensuring optimum access and monitoring.
The control panel should be located outside of the hazardous area that it is monitoring.
Easy accessibility is required both for status observation and alarm purposes.
Where connections may exceed 500 yards from one control panel –Contact your supplier!
The use of sound strobes are highly recommended!

Designed for surface mounting, it must be installed by a licensed, insured contractor.
1. Carefully remove the front cover from the unit by
unscrewing the four bolts located at each corner. To do
this –use the socket wrench provided.
2. Mark the four screw holes located on the back of the
enclosure to the wall. Ensure the wall surface is flat to
prevent base distortion.
3. After executing the mounting and the connections –
replace the front cover and insert the security caps over
the four bolts.
Board Connections Diagram
Be careful when creating access for cables –Damage to boards will void any warranty!
Any damage attempting to remove the circuit board parts may void any warranty!
Wiring of different circuits shall be separated by means of routing, clamping or barrier!
All Class 2 wiring is to be installed within flexible tubing to maintain segregation between circuits!
For MODBUS communications, a shielded and twisted pair cable is used!

Installation & Operation Manual Parksafe
AGS Parksafe Panel - IOM Iss: 6 10-20 6
Board Connections Overview
1. POWER/ LINE IN 110-120Vac mains power should be supplied to the [POWER/LINE IN] connector
using a 3 core cable and fused at 3A. When mains power is supplied to the panel - a red LED
will illuminate located on the front cover.
2. OUTPUT 1 RELAY This relay output switches when any external gas detectors reach ‘pre-alarm’
status and the [0-10V OUTPUT] will send 5V to ventilation systems.
OUTPUT 2 RELAY This relay output switches when any external gas detectors reach ‘alarm delay’
status and the [0-10V OUTPUT] will send 10V to ventilation systems.
ALARM RELAY This relay output switches when any external gas detectors reach ‘alarm delay’
status for longer than the selectable 1-5 minutes time following the [OUTPUT 2] relay.
DAMPER RELAY This relay output can switch together with either OUTPUT 1, OUTPUT 2 or ALARM
relays - selectable in the settings menu.
3. DETECTOR CHAIN 12-24Vdc power and Modbus communication data is wired to Parksafe gas
detectors [DETECTOR CHAIN] - [+ / - / D+ / D-].
Up to 16 detectors can be connected, chained in parallel up to approx. 500 yards from the
panel depending on chain configuration, wire type for power and condition.
Connect detectors in a parallel (daisy chain) method. Any other way may cause
communication issues or damage to the overall system.
For MODBUS communications, a shielded and twisted pair cable is used. The shielding can be
of 2 types: braided [mesh of thin conducting wires] or foil (consisting of a thin sheet of metal
covering the twisted wires).
If you are encountering noise or irregular problems with a Modbus link, the problem is likely
related to grounding, incorrect shielding or wiring mains power next to Modbus wiring.
For more information refer to your Parksafe detector manual.
4. SOUNDER/ STROBE This relay output (24VDC) is for an external sounder alarms/ strobe lighting to
activate on alarm.
5. 24VDC This is a permanent 24Vdc power output for external auxiliary devices.
Max output: 200mA.
6. 0-10V OUTPUT This output can drive ventilation systems. Under normal operating conditions, this
output can send either 0 or 2V –selectable in the settings menu. The [0-10V OUTPUT] will send 5V
when [OUTPUT 1] relay is activated and 10V when [OUTPUT 2] relay is activated.

Installation & Operation Manual Parksafe
AGS Parksafe Panel - IOM Iss: 6 10-20 7
Wiring your Detector
Power and Modbus data are wired between detectors with the first
connected to a control panel DETECTOR CHAIN terminal.
For MODBUS communications, a shielded cable is used.
The shielding can be of 2 types: braided [mesh of thin
conducting wires] or foil (consisting of a thin sheet of metal
covering the twisted wires).
One example of such cable is BELDEN 3082A.
If you are encountering noise or irregular problems with a Modbus link, the problem is likely related
to grounding, incorrect shielding or wiring mains power next to Modbus wiring.
To ground the data cable, the shield should be connected to [-] of the chain terminals.
Reversing the [D+] and [D-] connections of any device can lead to the whole system to stop
working owing to reverse polarity found on the terminals.
Not appropriately grounding the device can give false readings, fail completely or turn into a
safety hazard!
Detector Chain ID Switches
When wiring multiple detectors in a chain it is important to identify each and
every detector installed for the control panel to receive and display accurate
data corresponding with the correct detector type.
The ID configuration diagram is printed onto detector boards for
quick reference. All detectors are factory set to ID1.
ID Switches must be configured for each and every detector connected to a
system to receive and display accurate data!
We recommend a plan, map and/or marking the detector enclosures detailing ID and location!

Installation & Operation Manual Parksafe
AGS Parksafe Panel - IOM Iss: 6 10-20 8
Creating a Detector Chain
Up to 16 Parksafe Detectors can be connected, chained in a parallel ‘daisy chain’ method up to
approx. 500 yards from the panel depending on chain configuration, wire type for power and
condition. Any other way may cause issues or damage to the overall system.
Remember to individually ID each connected detector by configuring the ID switches on the circuit
boards. Make a plan and/or map of the location of all detectors for tracing and locality purposes.
It is recommended that the cable of same color should be used to connect all [D+] terminals
together and similarly cable of same color to be used to connect all [D-] terminals together.
**Split chain example. **Single chain example
**Where connections may exceed 500 yards from one control panel –contact your supplier!
Remember to ID your detector!
120 ohm Termination Resistance
Signal communication issues may occur where the bus length is too long, high baud rates are used
or signal reflections are occurring. To avoid this, terminating at each end of a chain may help the
quality of the data signal by turning on the 120ohm terminal resistor switch.
Split chain Single chain
For more information refer to your Parksafe detector manual.

General Maintenance
Keep your Parksafe system in good working order follow these basic principles;
Remove any dust/debris from the outer enclosure regularly using a slightly damp cloth.
Never use detergents or solvents to clean your gas detection devices.
Never spray air fresheners, hair spray, paint or other aerosols near devices.
Never paint devices. Paint will seal vents and interfere with the device.
It is recommended that detectors are inspected and serviced at least annually from the date of
installation for optimum performance and protection due to sensitivity drifts!
High concentrations of alcohol found in many products may damage, deteriorate or affect the gas
sensor such as; wine; deodorants; stain removers; thinners etc. Other gases and substances to
avoid are; Corrosives (i.e. chlorine & hydrogen chloride); Alkali metals; Basic or acidic compounds;
Silicones; Tetraethyl lead; Halogens and halogenated compounds!
EOL or Service Indication
This message will appear on the home screen and indicates that a gas sensor module has reached
either its expected operational lifecycle (EOL) or that the detector(s) require its periodic service
check. Press the ‘GAS DETECTION’button on screen to identify the affected detector(s) and status.
No gas levels will be displayed for that detector during this time.
The expected operational life of a gas sensor module will depend on the type of gas your detector
is targeting and may vary depending on environmental conditions.
When a gas detector displays the ‘End of Life’ message contact your supplier immediately.
It is important to maintain the gas sensing elements of gas detectors for optimum performance,
protection and security of the system. When the detector displays the ‘SERVICE’ message contact
your supplier immediately. Parksafe gas detectors will still operate 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 detectors are inspected and serviced at least annually from the date of
installation for optimum performance and protection.
Contact your supplier for more information.

Bump Testing
What is Bump Testing?
Bump testing is a term used for checking a gas detector is functioning correctly by exposing it to
the target gas. A known concentration of the target gas is applied to the device to trigger an
alarm condition and ascertain the detector is working safely.
Why is it Important?
A detector may visually appear in good order, 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.
The aim of the bump test is to make sure a gas detector is working at its optimum by briefly
exposing the unit to a known concentration of the target gas. The reading (if displayed) is
compared to the actual content of gas present, as stated on the test gas cylinder and if the
detector goes into alarm within an acceptable range of the actual concentration, usually within
10%, then it is working safely.
If the bump test results are not within the acceptable range, the gas detector must not be used
until a full calibration has been conducted.
Bump testing has a number of benefits for the end user:
Peace of mind that the system does actually detect the gas in question.
Allows the site to practice safe operations in a similar manner to the fire system.
Early indication of any issues.
How Often?
Regular bump tests are important to make sure the detector is able to detect a release of gas as
early as possible. A bump test usually takes seconds (gas type dependant) and is often completed
alongside a scheduled fire alarm test, however the frequency should be determined following a risk
assessment by the end user.
Current standards recommend that for new installations - it may be prudent to carry out a bump
test frequently, following a successful initial period and as confidence grows in the installation
concerned, the frequency could be reduced.
Remember, bump testing does not remove the need to have gas detectors inspected, calibrated
and serviced periodically by a trained engineer. You should not attempt this yourself and should
employ the services of a specialist company.
