ACTIVATION METHODS
The Ivy unit can be triggered by signals from the panel, depending
on the wiring method used and also by events generated by the Ivy
unit itself.
Signaling will cease when one of the following conditions occurs:
• the alarm condition clears;
• the maximum alarm time expires (in this case, only the audible
signaling will cease);
• the STOP signal activates.
If, during an active alarm, the maximum audible-alarm time expires
(Table 7, Maximum duration of audible signaling), audible signaling
will cease but visual signaling will continue until the trigger condition
clears.
3-1Types of signal
SOUNDER/
FLASHER EVENTS
The Ivy unit processes the signals it picks up and then generates the
respective events (which can be associated with one or more
signals).
The Ivy unit can generate the following events:
• Power failure
•Low battery
• Battery inefficient
•Open casing
• Device dislodgement
• Foam tamper (or similar) in the horn
• Blow torch tamper
• Horn damage
Note The audible and visual signaling triggered by “open casing”, “foam
tamper” and “blow torch tamper” events will clear after 30s, or
immediately on receiving the STOP signal.
MAINS FAILURE This signaling method is widely applied as it ensures intrinsic
protection against wire-cutting. This activation method triggers
audible and visual signals (sounder and flasher) when the primary
mains power fails.
START INPUT The START ancillary input is completely programmable, therefore, it
can activate the sounder/flasher by means of either positive signals
(Applied/Removed) or negative signals (Applied/Removed).
