Supervision Messages (RF version only)
ALC transmits supervision messages which alert ELC (Elpas Local Controller) in case the ALC antenna or synch cable is disconnected, the
tamper is triggered or restored, ALC is lost or online, or if the voltage is low. ALC Outdoor LF BUS Beacon with Loop provides two options for
supervision messages transmission, RF and BUS. When RF is in use, ALC does not require connection to additional devices. ALC transmits
supervision messages to ELC through RF. In BUS, ALC is wired to ELC through RS-485 BUS which transmits the supervision messages.
ID Address Setup
Before initial power-up, the Primary ALC LF BUS Beacon must be assigned a unique ID Address (Neuron ID) in order for the Eiris Software
Platform or an Elpas Local Controller to be able to identify the device. Convert the Neuron ID (typically using a scientific calculator) into the
two-digit hexadecimal number that correctly corresponds to the DIP switch found on the LF Beacon. This hexadecimal number is used to
register the beacon ID address into the Eiris or the ELC database.
Note: It is vital that a newly assigned ID Address does not conflict with any other ID Address that is already assigned to any other beacon.
These Neuron ID Addresses SHOULD NOT BE ASSIGNED to the Primary ALC LF BUS Beacon: 0x00 (00000000), 0x13 (00010011),
0x35 (00110101), 0x4B (01001011), 0x4D (01001101), 0x5C (01011100), 0xB8 (10111000), 0xD5 (11010101), 0xDC (11011100), 0xFF (11111111),
0xFE (11111110) and 0x7F (01111111).
If any of the above ID addresses is assigned by mistake, the beacon does not function properly. Additionally, the beacon Red Status LED flashes
continually; and the device buzzer is sound repetitively.
Secondary ALCs IDs:
 When connected to ELC, ALCs set as secondary do not require an ID. If an ID is set, Eiris ignores it.
 When used as standalone, transmitting to Eiris, use the extra four DIP switches to set a secondary identifying number for secondary ALCs. Make sure the
extra four DIP switches in the primary ALCs are set to 0. Otherwise, Eiris events recognize them as secondary ALCs.
Use the beacon 8-poisition DIP Switch (added 4, only for secondary ALCs) to set the ID address (in binary format) of the beacon as illustrated
below.
The ID address is assigned using a binary coded hexadecimal number.
Switches 1-4 (high nibble) are used to set the first hexadecimal digit while
switches 5-8 (low nibble) are used to set the second hexadecimal digit.
Together, the two hexadecimal digits provide a total of 256 possible
Neuron ID addresses.
The figure below shows how to set the hex digitals ‘0’ to ‘F’
Below are three examples of addresses set in hexadecimal:
