
To assign a tone other than the default to any channel, program the unit.

The input channel tone broadcasts when the channel is activated by a
contact closure. If a higher priority input channel is already activated, the
lower priority tone does not broadcast.
Tip: There are 10 tones
to choose from.
See: Programming,
Setting Input Channel
Alarm Tones, below.

To select either a level-triggering or positive edge pulse-triggering signal,
program the unit. The AG17 is preset for a Pulse-Trigger Logic Input
default.

Lower priority triggered channels are suppressed until higher priority
channels are released. Front panel LEDs indicate all activated channels.
Tip: The type of
triggering selected is
applied to all input
channels.
See: Programming,
Setting Triggering and
Attenuation, below.

The alarm tone associated with the activated, highest priority channel is
generated until the Timer or the Reset Switch resets it.

The unit is preset with the Timer Reset disabled so tones continue to
sound until the reset switch is pressed.

To enable the Timer, program the unit. Timer duration on the AG17 can
be programmed for tones operating from 30 seconds to 30 minutes.
Tip: The Timer
determines the length of
time the alarm sounds
before it automatically
resets.

Pressing the Reset switch clears the highest priority activated channel.
See: Programming,
Setting the Timer for
Pulse Triggered Logic
Inputs, below...
Alarm Logic Outputs
Logic Outputs are used to connect devices (e.g., strobe lights, relays) that
trigger when an alarm is activated. Each Logic Output Channel is associated
with the corresponding Logic Input Channel number. Tip: Each Logic Output
Channel is an isolated
open-drain circuit.

Wire Logic Outputs according to standard Open-drain / Open-collector
procedures.
Note: The maximum
rating for each logic
output is 300 mA at 40 V
DC.

Do not apply positive DC voltage to the source terminal or hook-up AC
voltage across the logic terminals.
Caution: Applying
positive DC voltage to
the source terminal or
AC voltage across the
source/drain terminals
will damage the AG17.
