S4 Security Information

S4 factory default will permit S4 to answer an incoming call

from any phone. This is to permit best flexibility so that the

Owner may install the S4 or the Owner may arrange for an

installation shop to do the installation.

In default state [factory default PIN is 12345], the Installer

can use any mobile phone to control S4 using text message

(SMS) or by calling S4. When basic installation and basic

S4 operations have been verified, then the Installer or the

Owner sends a text message that sets the Owner's mobile

phone in the S4. Once this is done, S4 will only respond to

incoming phone calls from the Owner's mobile phone.

Then the Owner sends a text message that changes the

PIN number to a secret PIN that is chosen by the Owner.

Once this is done, S4 will only respond to text messages

with the Owner PIN.

There are two exceptions –

•

If the Owner sends S4 a text message instructing S4 to

'authorize' a particular phone number, S4 will accept certain

commands from that phone number (provided the message

has the Owner's PIN). This permits the Owner to authorize

up to two emergency contact numbers.

•

If the Owner (or authorized phone) has commanded S4 to

call 911 and the 911 call should be suddenly terminated, S4

permits 911 to call back to S4 and S4 will answer for a

prescribed period time. Otherwise S4 will not accept a call

from 911 or any other non-authorized number.
