4. Installation requirements
The requirements for the proper installation of the Jcall system are:
•
If installed outdoors, the board should be housed in a suitable enclosure to protect it from moisture, water, dust and heat.
For this purpose, Jcall can be installed in the "Model E" enclosure, which is available as an accessory, using the metal plate
and screws provided with the installation kit.
•
Installation in a zone with no GSM coverage. If the GSM signal is weak or the signal is received from multiple GSM cells at
the same time, at certain moments the controller may not be reachable. If these conditions persist after checking the
coverage, it is recommended that you change the phone network operator that supplied the SIM card.
•
The availability of a GSM SIM card (of an operator that provides 2G GSM network coverage) that has had the PIN
protection disabled.
Jcall also allows the access system to which it is connected to be operated remotely: which is why the installation must be
carried out in compliance with current safety standards.
5. Installation procedure
To install the kit, follow the steps below:
1.
Before inserting the GSM SIM card on the board, make sure that it has been activated by making a call of a few seconds
using a mobile phone. The PIN of the GSM SIM card also needs to be disabled before it is inserted in the board. If
necessary, contact your SIM retailer.
2.
Insert the GSM SIM card into its housing. The gold coloured contacts of the SIM card should be facing downwards.
3.
Connect the GSM antenna. The antenna must be placed in an area covered by the GSM service: avoid placing it in
closed metal containers or inspection chambers.
4.
Connect the output terminals to the electrical circuit to be activated as described in section 6. Make sure that the
characteristics of the circuit to be activated are compatible with the specifications of the relays.
5.
Plug in the power connector. You may need to wait up to 2 minutes after power has been turned on to the board before
the system is fully functional. The board is operational when the operational LED is lit (see e Figure 2).
6.
Check the "GSM network registration" LED (lFigure 2): when the board is correctly connected to the GSM network, the
LED flashes briefly every 4 seconds. If it does not, make sure that:
a.
The SIM card has been inserted properly in its housing
b.
The SIM card has been activated and its PIN has been disabled
c.
The antenna has been properly connected and that there is GSM coverage
7.
Send an SMS containing the text "MASTER" to the GSM SIM card number: Jcall will record the number of the sender as
a number authorised for programming via SMS. A welcome SMS will be received as confirmation.
WARNING:
The number enabled for programming can be changed only through a card reset (via SMS or a hard reset) or via
the Jcall Manager software.
8.
Enter the users that are enabled to open the entrance via SMS (see section 9) or via the Jcall Manager software.
9.
The Jcall system can be activated by simply sending a ring from one of the enabled numbers. The Jcall board will
activate the opening contact and operate the access system only if the caller number is listed among those authorised.
WARNING:
To activate Jcall, the caller's number must be visible to the receiver. If a registered user has enabled the "hide
number" option on his phone, when calling, he must enter *31# before the number of the Jcall SIM card e.g. *31#3471234XXX.
WARNING:
When entering a landline number in Jcall that is connected to a switchboard, make sure that you enter (via SMS or
the Jcall Manager software) the telephone number as it actually appears from outside the switchboard.
6. Connecting Relays
The Jcall board has 2 electromechanical relay outputs (OUT1 and OUT2) to operate up to 2 accesses that can be connected via
the connectors shown in point d Figure 2. Each output allows you to connect the automation system contact in a normally open
"NO" or normally closed "NC" position, depending on the type of automation system to be connected. The maximum voltage and
current rating of the relay outputs are shown in section 12.
WARNING:
The wide coverage of the GSM network means that the caller can operate the accesses connected to the Jcall from
anywhere, provided that he/she is enabled to do so. When the system is installed, presence detectors can be installed in order to
ensure proximity of the user to the entrance.
WARNING:
By adding an expansion card, available as an accessory, a single Jcall board can manage up to 10 relay outputs (so
up to 10 entrances can be controlled by a single board).
