HISTORY:
Sustainability is the name of the game! Anything (that has been tested and still functioning properly) should be repurposed creating saving in wasted Ee and reducing the poisoning our environment when items are buried in the earth at the local tip needlessly.
Never heard of Ee? It is a concept that creates a measurement of ALL things (not just electronics) that humans have made and the energy used in obtaining the raw material, processing the materials right through to a finished product and even should include the shipping of the item to the distributors/retailers.
If you would like to know more about Ee values, please take a look HERE
I did have a number of alarm systems and auxiliary equipment for our various premises of days gone by, this key pad is one of those items.
It is offered only on the basis of AS-IS because I no longer have the system unit and my testing of the key pad is pretty rudimentary (see below for details)
GENERIC - Alarm System Key Pad SPARE PART
USED
Key Pad ONLY
Part # 38-0024 Rev C (PCB identification)
Technology used: Serial data (asynchronous)
Numerical keypad
Keys also for FIRE, AMBULANCE, POLICE, ON, PARTIAL, EXIT, BYPASS & CHIME
Fully protected LED display (not LCD)
Drop down keypad cover
3 hardwired connections at the rear (inside) for connection to the alarm system (Positive, Negative & Serial Data)
DIMENSIONS:
144mm height x 75mm wide x 30mm thick
Door only: 96mm height x 75mm wide with 2x pivot plugs 4mm diameter x 2.5mm length
Note that the door is "shaped" on the sides so that it fits nicely to the main body and has an overall slight convex curve
Weight: 200g
COSMETIC CONDITION:
USED
CLEAN
NO scratching
NO discolouration of note
NO front display panel damage
NO case cracking
DOOR HINGE is secure (so often I these will fail over time from improper handling)
TESTING:
I am unsure if this keypad is functioning correctly or not, I do not have the matching alarm system any longer
Applied 12V and NO serial data signal
Result was the FIRE LED indicator flashes rapidly & the SERVICE LED indicator is on constantly
The internal piezo audio transducer makes no sounds
Pushing any key had no effect at all and the same goes for the "RESET" button at the rear of the case
I did have a source of serial data (but most likely not compatible) from another alarm system, synchronous data. I knew this wasn't going to work but tried it anyway.
The keypad sort of "came alive", keys now responded and I managed to achieve BYPASS lighting up, then after around 10 seconds it goes out. All keys did result in a "confirmation beep" from the audio transducer so I believe the keypad was trying to respond but of course the serial data stream would not have been "understandable" by the keypad.
So this keypad is offered for experimentation or even spare parts, I know from experience those drop down doors are a pain as over time the hinges become damaged by the users. Removal of this door is undertaken by carefully bending the side pivots slightly outwards and it will come free reasonably easy - don't over do it though otherwise the plastic may become stressed or even crack!
In summary, I "think" this keypad is fine but I am unable to verify this.
As a result, this Generic key pad is offered on an AS-IS basis
This control panel is now stored in sealed plastic and will be supplied in this manner.
