Installation and Programming manual
2 WIRE
CONNECTION
This standard wiring method activates the alarm signal by means of
a positive-power-removed signal.
4 WIRE
CONNECTION
This wiring method activates signalling via the START terminal and
deactivates it via the STOP terminal. The polarity of both inputs is
programmable.
The sounder/flasher is activated by an open-collector output (on the
intrusion control panel). By means of a second open-collector
output, you can deactivate alarm signals and disable (block) the
sounder/flasher from the intrusion control panel, for example,
during maintenance sessions.
I-BUS
CONNECTION
Only the Ivy-BF, can be connected to the I-BUS connections on the
Ness SmartLiving Series panels. This connection allows you to
program the device and activate alarm-signalling directly from the
panel.
In addition, connection of the I-BUS wire to terminal "+", provides a
power source which enables the Ivy unit to activate alarm-signalling
(in accordance with its programmed parameters) in the event of
wire-cutting tamper.
Each time the SmartLiving panel resets the BUS and restarts the
connected peripherals, the Ivy unit will run a 60-second status
check on the BUS, as described in paragraph
2-1 Installation
guidelines
