10 Signaling
Installation and Programming manual
Chapter 4
SIGNALING
The Ivy unit provides various signals: audible, visual, activation of the
FAULT and TAMPER outputs (connectable to the intrusion-control
panel).
Each signal type can be programmed separately, combined with
other signals, or deactivated.
4-1Types of signaling
VISUAL SIGNALING
The super-bright flasher uses new-generation Light Emitting Diode
technology which provides maximum visual-signal clarity with extra-
low power consumption. The flasher circuit is divided into two
groups, the left group (Table 4, G) and the right group (Table 4, H).
This type of circuitry allows you to select the options on the
Programming menus.
STATUS LED -
PRG LED
The two ancillary LEDs, reveal the device status and guide you
through the programming operations (STATUS LED - Table 4, Q;
PRG LED - Table 4, R).
These two LEDs, with proper programming, signal faults and
tampers of the sounder/flasher; please refer to paragraph 4-2
Tamper memory and fault signaling.
AUDIBLE
SIGNALING
The magneto-dynamic horn provides a choice of 4-tones, which can
be programmed with a maximum alarm time and assigned to
indicate different alarm types.
FAULT OUTPUT
Open-collector output with 100mA maximum current draw capacity.
During the programming phase, it is possible to select the standby
status (Normally open or Normally closed) and assign the events.
TAMPER OUTPUT
The voltage-free relay can be used to signal tamper conditions to
external devices. During the programming phase, it is possible to
select the standby status (Normally open or Normally closed) and
assign the events.
4-2Tamper memory and fault
signaling
The STATUS and PRG LEDs provide visual signaling of horn faults
and tamper memory by emitting a series of fast blinks (at 0.5
second intervals). This visual signaling phase lasts for approximately
