Description
QALERT
General Alarm Horn/Strobe (horn on-til-silence;
strobe on-til-reset). Use for NAC circuits containing
both horns and strobes.
Compatible visual-only devices include:
• 4906-9101, wall-mount, visual-only, red
• 4906-9102, ceiling-mount, visual-only, red
• 4906-9103, wall-mount, visual-only, white
• 4906-9104, ceiling-mount, visual-only, white
Compatible A/V devices include:
• 4906-9127, wall-mount, red
• 4906-9128, ceiling-mount, red
• 4906-9129, wall-mount, white
• 4906-9130, wall-mount, red
Compatible audible-only devices include:
• 4901-9820, wall-mount, red, horn only. Horn
must be selected for two-wire horn strobe con-
trol. See Horn Instruction manual.
SSIG
General Alarm (on til-silence). Use for NAC circuits
containing only audible devices.
Compatible audible-only devices include:
• 4901-9820, wall-mount, red, horn only.
RSIG
General Alarm (on steady-til-reset). Use for NAC
circuits containing visual-only devices.
Compatible devices include:
• 4906-9101, wall-mount, visual-only, red
• 4906-9102, ceiling-mount, visual-only, red
• 4906-9103, wall-mount, visual-only, white
• 4906-9104, ceiling-mount, visual-only, white
SUPV
NAC activates when there is a supervisory condi-
tion active in the system. NAC is on until supervi-
sory condition is cleared.
TRBL
NAC activates when there is a trouble condition
active in the system. NAC is on until trouble condi-
tion is acknowledged.
UTILITY
NAC activates when an initiating device with the
following attributes activates:
• IDC must be in same alarm group as utility NAC.
• IDC must be assigned a Utility function type.
Typically used for process monitoring function. For
example, a relay on a machine is tied to the IDC.
When the relay activates, the utility IDC activates
and triggers the utility NAC.
Table 5-2 NAC Operation Settings
Operation Description
Temporal
Standard Temporal coded pattern. A three pulse
coding pattern consisting of three ½ second
pulses, each separated by ½ second silence. Each
group of three pulses is separated by 1.5 seconds
of silence.
Synch
Generates synchronization pulse for visual-only
NAC circuits that use the following visual-only
devices.
• 4906-9101, wall-mount, visual-only, red
• 4906-9102, ceiling-mount, visual-only, red
• 4906-9103, wall-mount, visual-only, white
• 4906-9104, ceiling-mount, visual-only, white
