An uninterruptible power supply with adequate power is essential for the product to
operate properly. The power supply must provide a power that can serve the minimum
operating voltage and the maximum power consumption of the device. The power feed
must be continuous and transient-free even when there is a mains power failure, and the
power feed switches to backup battery operation.
An ideal solution for the above purposes is the power supply designed and manufactured
by TELL, which we expressly recommend using for our communicators.
• Recommended TELL power supply for use with an alarm control panel:
TT40VA-16VAC/24VDC, which provides power feed (16V AC) also for the alarm control
panel at the same time.
• Recommended TELL power supply for other use: TT25VA-12V5.
2.2 Input wiring
For the inputs, the normally closed or normally open dry contact should be connected between
the given input (IN1…IN4) and the negative of the power input (V-) or the COM terminal.
If a normally open dry contact is used to activate the input, choose the NO (normally open) option
in the given input’s settings. In this case, the input will become activated when the open contact
between the given input (IN1…IN4) and the V- terminal (or the COM terminal) becomes closed.
If a normally closed dry contact is used to activate the input, choose the NC (normally closed)
option in the given input’s settings. In this case, the input will become activated when the closed
contact between the given input (IN1…IN4) and the V- terminal (or the COM terminal) becomes
open.
2.3 Output wiring
The output provides normally open (N.O.) dry (potential free) relay contact by default and closed
contact upon control.
2.4 SIM card holder
The device requires a Mini (2FF) size SIM card.
The SIM card holder can be accessed by removing the cover of the aperture found on the device
enclosure.
Note: the WiFi device model does not require a SIM card, therefore it has no SIM card holder.
The cover can be removed by pressing it with your fingernail towards the LED at the end where
the gap is and then pulling it outwards. Insert the SIM card in the holder. The services to be
activated on the SIM card installed into the Adapter2 device should be chosen according to which
services of the device you wish to use. Basically, for communication with receivers and servers it
requires a SIM card with mobile Internet access that may use either public or private APN. The
functions that use SMS sending need SMS service and the ones that use calls require GSM voice
call service.
