ebay wireless gsm alarm burglar system

GSM Alarm burglar system with wireless sensors
I buy that item from ebay. There are a lot of a such alarm system, that when an alarm is triggered (from PIR, contact or fire/smoke sensors) an SMS is sent (the figure is mirrored).

I encountered a lot of difficulties during the initial setup phase so I decided to write a "manual"; the system auto learn the sensors, but the procedure and the cabling scheme are totally absent, so it's very very difficult to use.
More in deep, surfing the net (a lot), I discovered that this is a 2nd generation one, so all the manuals about the 1st generation (without auto learning) are totaly unuseful, and finally the wireless siren need a bizzarre autolearning procedure (while the cabling is simply ... not present in the manual).

I think that the solution is good and very cost attractive but the lack of manual is a big big contro; there are so many flavours that the surfing is not so helpful but all the products (IC, etc) seems developed from one or two big chinese companies:

Silicon Valley is the past as Shenzhen is the future ...

BTW ...

Central Unit:

• it's a 2nd generation system, with autolearning of sensors
• the sensors (PIR, contact open/door, smoke/fire, gas) trigger the abnormal situation, when alarm is received from the central unit, it send SMS up to five (or similar) pre-setup phone numbers
• it support 2 partitions (but I cannot able to use the inner one, so I "declared" all sensor in the external one), 16 (some more) wireless zone and 3 wired zones
• 1 relay output (2 contacts) to drive a home appliance (100W max), and 2 open collectors (SMS driven)
  
• two ways/accesses for the setup: SMS or wireless keyboard (that "fillup" a zone)
• remote controllers have 4 button: out arm, home arm (only "external" sensors), disarm and direct alarm (the "siren" button)
• sensors can be all-deleted (no partially) or added:
• hold the reset and power on to total delete (sensors, zone names, phone numbers)
• power on AND hold on reset for 1 second to go into "inner auto learning " or "home arm" (It does not work for me) ... wait 20 secs to automatically exit
• simply power on, without intervention to go into "outer auto learning" or "out arm" (20 secs)
• ordered add:
• I want setup the environment offline, declaring PIRs first and door/open then, because each zone has a customizable SMS text, but only the first five (5) have dedicated message; from 6th to 16th zones there is an unique message text that shall be sent when an alarm triggered, btw the last part of each message report the zone (f.e. "wireless activated (07)" is the default)
  
• go into "outer auto learning"
• power the fire (circular) sensor (via test button), after a central unit blinking power off the sensor
• power on the PIR, and power off after central unit blinking
• power on the open/close contacts and put away the two parts (basically to learn a sensor, it must send an alarm), and power off
• press the alarm (siren) key in each remote controller (each one fillup a zone)
• press the panic sensor/button
• the sequence allow to assign dedicated/explicit message to most important sensors (fire, etc), and reserve the general/unique message for secondary ones (6-16 zones)
• sensor jumper switches:
• all sensor have two main group of jumpers A0-A7, D0-D3; incongruent settings inhibit correct behavior
  
• 1st generation systems required that "A"jumper reflect the "host number" (a label on back side of the central unit, each digit had 0, 1 or 2 value); with 2nd gen it's unuseful (auto learn), so I assigned an unique code to each sensor
• in my working configuration each sensor (PIR or contact) MUST have the SAME "D" bits value (i.e. D0-D3=LHNN=0, 1, NC, NC is a possible one)
  
• timer (default) = 5 secs
• select rx (default) = 4.7M (3-4)
• len on/off (default) = on
  

Sensors:

• PIR: on/off switch, customization: led on/off, delayed start
• open/close contact: wireless transmitter, working method/setup similar to PIR; 3,5 cm to trigger the alarm
• smoke/fire: little siren, no jumper, auto-learned by the system in the usual way

wireless Siren (big trouble):

• various models (strobe, light, wired, etc) exist, I have the wireless light one (I have no cables from siren); the manual is scrap and the two main problems are cabling and auto-learn
  
• a such sirens can act as a standalone system (that auto learns sensors, without a central unit too) or as a normal siren controlled by a central unit
• auto-learn
• as a controlled siren (i.e. not a standalone system) could be necessary to register the central unit into the siren
• power on the central unit with the transmitted connected and powered, wait the completition of the startup process; put (if not) in disarmed state
• power on the siren, wait 1 minute the end of startup
• hold on the small black button on the left side of the siren (delete all), after beep/flash press the button; to be sure cycle power (follow the previous step)
• press and leave the black button, the green led start blinking, the 3 red ones flash, and and a strong beep will be auditable
• use a remote controller or a panic button to raise an alarm, i.e. the system is disarmed, but with panic or "siren" button in the remote the system is armed and raise the alarm; wait the siren beep/flash (the wait could be till 1 minute) and the re-press the black button in the siren ....
• OK system is registered into the siren
• cabling
• the basic schema is the one in the figure, the transmitter would use a different frequency from central unit - sensors (i.e. 315 MHz siren vs. 433 MHz sensor or viceversa)
• transmitter uses a bypass to power itself: normally the manuals does not specify where connection take in place, if to the central unit or siren; the correct is connect the bypass to the central unit, place the transmitter as far as possible (30 cm cable is provided ...)
• connect the single cable of transmitter to the "siren" contact of the central unit; the same that is used for the indoor siren
• the siren has two holes and a button: connect the power adapter (the bigger one), don't use the jack (similar to a stereo-hifi one)
• in my case the wireless receiver is already integrated into the siren (remember "wireless light siren" nickname); the one above is the most complete scheme suitable for wired-wireless siren
  

Surely to be useful, Good luck.
