DIGIAIR PRO 3 – RADIO

Use a Signal Analyser (available from the CSL Installer Shop) to determine if enough base stations (2 or more) are available at the site and that they can supply sufficient signal strength (30% and above). This will determine the optimum location for the DigiAir Pro 3’s aerial to be mounted.

If you do not have a Signal Analyser, we recommend powering up the DigiAir Pro 3, connecting the aerial/s, going through the commissioning process then checking the signal strength before permanently fitting the aerial.

Press the A button to show the signal strength – LED 1 should be green to show an acceptable level of Radio signal/quality.

DIGIAIR PRO 3 – LAN

DigiAir Pro 3 uses DHCP as the default IP setting. Fixed IP settings can be added or amended using the My Base App. Fit the Ethernet Cable to the device and connect to the customer’s router. Ensure the customer’s LAN socket is live and their network allows access to the CSL servers.

Visit the CSL Live Support Page for information about our Customer IT Survey Form.

The ETH LED will flash between red, amber and green to indicate the connection is operational and data is being seen on the local network link.

DigiAir Pro 3 must be installed within an enclosure suitable for the installation certification. The unit should be fixed securely using the adhesive pads supplied or via the screw fixings accessible by removing the lid.

Once fitted, ensure:

• The aerial is connected, or the ethernet cable is installed, as appropriate
• The alarm panel or PSU is powered down
• Wire the DigiAir Pro 3 in this order.

1. Negative (-) power,
2. Positive (+) power,
3. Serial cable or inputs

• If required, connect the serial cable – RS485, RS232 or TTL (panel dependent) – see Panel Connections section for more information
• Connect any hardwired alarms into the device – see Pin Triggering section for more information
• Connect the fault output
• Ensure that all inputs are electrically isolated
• Restore power to the alarm panel or PSU

POSITIONING THE AERIAL

On power-up, the DigiAir Pro 3 will automatically contact the Gemini Global Platform to perform its commissioning process, which can take up to 5-8 minutes.

Once commissioned, all 3 LEDs will light green for 5 seconds. The device will then reboot.

Press Button C once from Quiescent/Normal State to send a Test Call

EXECUTE PIN LEARN

From the Quiescent/Normal State, press and hold Button C for 5 seconds to allow the device to perform a self-learn of the current input pins. LED C will flash once complete. See Pin Triggering in the Panel Integrations section of this guide for more information.

Your device will come pre-configured to connect to the panel using pin triggering. In My Base, it will show Panel Type = pins only.

A panel can also be connected using:

• Dial Capture (PSTN Modem)
• TTL
• RS232 (including ATS 7090)
• RS485
• Ethernet

To enable any of these connections to a control panel, install the appropriate cabling, then go to the My Base App and select the correct panel type. See the Panel Integrations section below for more information.

Panel guides can be found by:

• Clicking the panel type (after selection) via the My Base App.
• Scan the QR code below.
• Visit the Installer Zone on our website.

PIN TRIGGERING

For this operation, the device is triggered by removing or applying zero volts to input terminals 1-8. No external pull-up resistors will be required. This is generally achieved via the digital communicator outputs of a control panel. On receiving an input to the pin terminals, the unit will signal alarm conditions and will generate the relevant messages and forward them via the Gemini Global Platform to the ARC. Installers are advised that the intended use should avoid situations where the rate of the trigger exceeds the rate at which messages are received at the ARC receiver.

Please read the panel installation guide with regard to the triggering of DualCom Pro input pins.

If the installation does not use relays to trigger the input pins (for example, positive applied), then the zero volts must be common between the power supplies of the panel and the DualCom Pro.

If the input pins are driven by relays from the panel and these are not electrically isolated, then consider introducing opto-isolators between the relays and the input pins, otherwise, the pins may not operate as intended.

CONFIGURING PIN INPUTS

To self-learn the current panel input status, press button C whilst in quiescent/normal state for 5 seconds. LED 3 will flash red twice once completed.

To change the input from negative removed or applied to positive removed or applied, change the pin bias via My Base under the Hardware menu button and use the A+ terminal instead of RTN.

DualCom Pro pin inputs 1, 2, 3, 5 – 8 generate SIA untyped alarms UA/UR8001 to 8012 on standard product configuration, e.g.

[#123456|NUA8001|AChannel 1 Alarm]
[#123456|NUR8001|AChannel 1 Restore]

DualCom Pro pin 4 Open / Close inputs generate SIA alarm OP and CL OP/CL8004 on standard product configuration, e.g.

[#123456|NOP8004|ASystem Set]
[#123456|NCL8004|ASystem Unset]

CONFIGURING OUTPUTS

Both outputs can be configured as either Normally Open (NO) or Normally Closed (NC), as required. Output 1 is defaulted to indicate a total path fail condition to the control panel. Output 1 can be reconfigured to indicate another path failure type, Output 2 can be configured as a manual trigger. To make any amendments, please use the My Base App.

Figure 6 – Example of Fault Output Wiring

PANEL CONNECTIONS

DIAL CAPTURE 

DigiAir Pro 3 simulates and replaces the phone line connection to the control panel’s Digi-Modem. The control panel’s Digi-Modem must use one of the following alarm formats: Fast Format*, Contact ID or SIA. In the event the control panel needs to send a signal to the ARC, DigiAir Pro 3 will capture the message and forward it, via Gemini, to the ARC. The Digi-Modem must have an ARC telephone number (ie 01) and account number (i.e. 1234) programmed for Dial Capture to work. If you want to monitor the Dial Capture connection, you will need to connect an output configured as PSTN line fault on your control panel to one of the DigiAir Pro 3’s inputs. That input then needs to be designated as Dial Capture Fail at your ARC.

*Please confirm the compatibility of Fast Format with DigiAir Pro 3 via your ARC.

Figure 7 – Dial Capture Wiring

DC09 CONNECTIONS

Only the DigiAir Pro 3 LAN can connect to a panel using DC09. The panel and the DigiAir Pro 3 must both be connected to the customer’s LAN.

SERIAL / RS232 / 485 / TTL PANEL CONNECTIONS

As standard, DigiAir Pro 3 is supplied with a serial cable compatible with Honeywell (RS485), Orisec (TTL), Pyronix (RS232), Texecom (TTL) and HKC (TTL) panels. Other types may require an additional cable/plug-in that can be purchased on our Installer Shop. It is possible to use pins and a serial cable together if required.

RADIO ONLY TROUBLESHOOTING

Q. How can I fail my signalling paths without having to disconnect them?

A. To fail each path from Quiescent/Normal state, press Button A. Press and hold B for 5 seconds to fail the primary path. The path will stay in fail mode or 15 mins unless you tap B again to restore the path.

Q. How can I check the signal strength of each radio module?

A. You can check the signal strength of the radio module on a commissioned device via the My Base App. Alternatively, when in the quiescent/normal state, you can press button A to toggle to the connectivity menu. Once there, LED 1 (first path) will show you the signal strength. We recommend a solid green LED (40% or 4/10 and above).

Q. Does my unit have a roaming SIM?

A. Yes, all DigiAir Pro 3 Radio devices come with 2 Roaming 4G SIMs

Q. My signal strength is 30% (3/10) or less or my LED is orange/red. What can I do to improve it?

A. You can improve this by:

• Avoid coiling the aerial cable
• Moving the aerial away from electrical equipment/wiring
• Moving the aerial to a higher point on the property or closer to a window/door

LAN TROUBLESHOOTING ONLY

Q. Why is my LAN path not working if my ETH LED is flashing green?

A. This means the device can see it is connected to the customer’s router, but there is a network configuration error. This type of fault can be due to the below:

• The network administrator has not amended the firewall rules as required. The required information can be found in the “Customer IT Survey Form” in the CSL Live section.

• If the device requires static IP addresses and these have not been added to the “Edit LAN Config” section of My Base. As standard, the site records are set up with DHCP.

Q. Why is my ETH LED not flashing if I have connected the ethernet cable to the device?

A. This means the device is not able to see a physical connection. We would advise testing the RJ45 ethernet cable and also making sure the port the cable is plugged into is live and not disabled/suspended.

Q. Does my device require static IP addresses?

A. No, it will also work with DHCP.

Q. Does the DigiAir Pro 3 support any type of negotiation speed?

A. No, the DigiAir Pro 3 will only support negotiation speeds of up to 100Mbps.

This section covers the requirements of a Fire installation and is a supplement for the GradeShift Pro 2 and DigiAir Pro 3. The guide uses DualCom Pro Fire to refer to both product variants.

Mounting

The enclosure requirements for the DualCom Pro Fire are the same as for the Fire Alarm Panel itself, which must meet the requirements of the EN54-21 standard.

The DualCom Pro Fire should be mounted inside the Fire Alarm Panel or inside a separately powered housing that meets the requirements of section 7.3 of the EN54-21 standard.

Input Pins

The default pin profile configured at installation is “PinLearn Fire”. With this, pins 1 and 2 are configured for use with fire alarm panels (EOL mode) and will generate a SIA Tamper Alarm/Restore in response to additional conditions along with Alarm and Restore with the other pins:

• Open circuit and open circuit restore
• Short circuit and short circuit restore
• Fault

If additional pins are required in EOL mode, use My Base to configure the DualCom Pro Fire to use pin profile “PinLearn EOL Pins 1-12”. In this configuration all pins on the DualCom Pro Fire will respond to the additional conditions and generate the corresponding events to the Gemini Global Platform.

• Pin 1: intended for receiving the Fire Alarm/Restore signal from the Fire Alarm Panel.
• Pin 2: intended for receiving Fault/Restore signal from the Fire Alarm Panel.

Remaining Pins: used for receiving notifications from any other device (e.g. an Intruder Panel). These pins take a lower priority than pins 1 & 2 when signalling to the Gemini Global Platform.

Input Pin Wiring

Please read the panel installation guide with regard to the triggering of DualCom Pro input pins.

If the installation does not use relays to trigger the input pins (for example, positive applied), then the zero volts must be common between the power supplies of the panel and the DualCom Pro.

If the input pins are driven by relays from the panel and these are not electrically isolated, then consider introducing opto-isolators between the relays and the input pins, otherwise,e the pins may not operate as intended.

Input pins, which are configured in EOL mode, require 10k and 4k7 Ohm resistors to be wired in line, as shown below.

The DualCom Pro Fire uses a normally closed configuration so that a power fail on the Fire Alarm Panel will signal an alarm to the Gemini Global Platform.

• If the circuit is broken, then an open-circuit tamper alarm will be generated
• If it detects 0v, then a short circuit tamper alarm will be generated
• If the wrong resistor values have been used, then a fault tamper alarm will be generated

Resistors

These are the colour code markings for the 10k Ohm and 4k7 Ohm resistors, respectively.

Self-Learn

If the self-learn functionality (Press Button C for 5 seconds) is invoked when an EOL pin isin the  Alarm State, then the DualCom Pro Fire will switch to generating a Restore event when a high voltage is detected for that pin going forward and an Alarm event when a low voltage is detected.

Relays

The relays are intended to notify the Fire Alarm Panel of events on the DualCom Pro, Gemini Global Platform or from the ARC. Their configuration is fixed in Fire Mode and cannot be changed via My Base.

When the DualCom Pro is unpowered, NC is connected to C, and NO is not connected to C.

When the DualCom Pro is powered and in a quiescent state, Relay 1 has the NO1 connected to C1 and the NC1 is not connected to C1.

If a fault occurs, then, Relay 1 changes such that NO1 is not connected to C1 and NC1 is connected to C1. When the fault is cleared it will revert.

Fault conditions include:

• If any of the input pins being monitored enter a fault state
• If there are communication path issues (Line Fault)
• If there is an alarm/restore that is sent to the ARC for one of the monitored pins and a response is not received within the configured timeout
• If there is a power failure

Relay 2 will connect NO2 to C2 and disconnect NC2 from C2 relay for 5 seconds to indicate that the ARC has acknowledged successful receipt of an event.

Relay Wiring

Fault Reporting

To meet the EN54-21 requirements for monitoring on Type 1 Fire systems, this device sends regular polling calls to the Gemini Global Platform on all connected and active transmission paths. The Installer shall ensure that appropriate reporting actions have been agreed with the ARC for all alarm codes, transmission path failure notifications and polling failure reports from the Gemini Global Platform.
