Secure Wireless EV-490 User manual

EV-490 Transmitter
Overview:
The Secure Wireless sample transmitter for AMAC has two tact switches on the printed
circuit board (PCB) that allow flexibility in operation and programming. When in
standard AMAC mode pressing anywhere on the top of the button will ensure that either
or both of the PCB tact switches will be depressed. If any tact switch is pressed, the unit
will send its transmission immediately.
Programming:
In programming you can choose to change the serial number OR change the operation of
the transmitter from supervisedto supervised with polling.
To change the serial number:
1) Press and HOLD both buttons on the AMAC sample transmitter. You will need
to press both the upper right and upper left corners of the one button to make
sure that you are pressing both buttons simultaneously.*
2) Continue holding the buttons, The LED will turn OFF after it is done
transmitting (approximately 3 seconds) and will turn back ON after
approximately 5 additional seconds, RELEASE both buttons.
3) Use the left tact switch for a ‘0’ and the right for a ‘1’. Example; if the AMAC
code that you desire is 28 then you will enter the data as follows;
0 0 1 0 1 0 0 0
_ _ _ _ _ _ _ _
4) You will also need to add a 0001 for a regular AMAC remote or a 1110 for a
silent panic type key.
I believe this encoding may be different from what you have done in the past but this is
the right format for Hex to Binary encoding.
5) Once all 12 digits have been entered the LED will flash rapidly.
* I have supplied a two button rubber insert for programming if you feel it is easier
during the programming sequences.
To change from Supervised to Supervised with Polling:
1) Press and HOLD both buttons on the AMAC sample transmitter. You will need
to press both the upper right and upper left corners of the one button to make
sure that you are pressing both buttons simultaneously.*

2) Continue holding the buttons, The LED will turn OFF after it is done
transmitting (approximately 3 seconds) and will turn back ON after
approximately 5 additional seconds, WAIT until the LED begins to flash
(approximately 5 seconds). The total hold time is approximately 13 seconds.
Once the LED is flashing, Release buttons.
3) Press Button # 1 (left) for Standard AMAC supervised unit. LED will confirm
choice with 1 flash OR Press button # 2 (right) for Supervised with polling,
LED will confirm choice with 2 flashes.
4) For testing purposes this unit will supervise itself every 10 seconds and will
send a supervisory heartbeat if programmed for supervised with polling.
* I have supplied a two button rubber insert for programming if you feel it is easier
during the programming sequences.
Battery Information:
Battery statistics are as follows:
4.8uA Standby Current
1.8uA Wake up time
.001uA Supervisory
.17uA 1 Button press per day
6.771uA Total battery draw
Batteryis a CR2025 with 160mA power
Calculation is as follows:
(160,000/6.771)/8760= 2.6975 years on average
This is actual field usage since you do not activate the battery until it is ready for use.
Supervisory with Polling Transmission:
When a heartbeat is sent every 12 hours it only sends that data packet 5 times. It does
NOT transmit for 3 full seconds.
It is Secure Wireless’ recommendation that you change your supervisory heartbeat to be
every 1-3hours so that we can transmit quickly and go back to sleep to conserve battery
power instead of transmitting in full every 12 hours. This does a few things for you. You
can miss multiple transmissions in a row a still not trigger a false positive and it allows
you to save some battery life. If you choose to do a full transmission every 12 hours your
estimated battery life will be 2.63 years.
Default Programming:
The AMAC unit will be pre-programmed at the factory with a standard code and
defaulted as a standard supervised device. Because this remote does not have EEPROM
when the batteries are changed you will potentially need to reprogram the serial number
and if it was supervised with polling before.

When the batteries are removed and replaced it will default to its original serial number
and as a standard supervised AMAC remote. If the unit had any other programming it
will need to be done again.
Low Battery Trigger:
Currently we check for a low battery every 12 hours for 3 consecutive wake ups. That
means that when a low battery is detected we must see it on three consecutive occasions
before we will lock and transmit low battery. When the AMAC remote detects low
battery it will take a minimum of 36 hours before it will transmit.
Although this can be changed to any other format,we feel this is best in case of low
temperature conditions. For example: If someone accidentally leavestheir remote in their
car overnight and the temperature drops below freezing, the remote may detect a low
battery since the batteries themselves drop voltage over temperature. We will wait until
two more sessions (24 Hours) before we will send a signal.
