Piezo

The piezo (local buzzer) generates different tone patterns for different event conditions:

•

Alarm -

Generates a steady tone, no pulse.

•

Trouble -

Pulses one second on, one second off. Repeats 30 pulses per minute.

•

Supervisory -

Pulses one-half second on, one-half second off. Repeats 60 pulses per minute.

Supervisory Service

Zone 4 is programmable for monitoring supervisory devices (such as valve tamper switches) by setting
SW1 DIP switch 3 to “ON” (see "Setting Mode of Operation" on page 27). A short circuit on this zone
(activation of a N.O. contact) will cause the supervisory LED and the zone 4 yellow LED to flash. The
piezo sounder will generate a unique sound. Pressing TONE SILENCE will silence the piezo and cause
the supervisory LED to illuminate steadily, but the Zone 4 Trouble LED will continue to flash. Supervisory
signals latch and require SYSTEM RESET to clear. The ALARM SILENCE switch will silence the piezo,
cause the supervisory LED to illuminate steadily and turn off the Supervisory Notification Circuit. An
open circuit on Zone 4 will be reported as a zone trouble.

Note:

The Initiating Device Circuit for sprinkler supervisory zone can be programmed for tracking operation; latching

operation is the default setting. Canadian regulations require latching operation; for programming instructions, See
“Sprinkler Supervisory Tracking” on page 32.

Zone Disable

If a zone has been disabled, an alarm that occurs on that zone will flash the red zone LED, but not the piezo
or any output circuit.

If both power sources are removed from the system, all zones will be re-enabled upon

restoration of power. Disable status will be lost.

The Zone Disable routine makes use of the four panel
switches as follows:

1. Press and hold in the TONE SILENCE switch.

2. With the TONE SILENCE switch held in, press

(in sequence) the ALARM SILENCE switch, the
ALARM ACTIVATE switch, and then the
SYSTEM RESET switch.

3. The Zone 1 Alarm LED will flash.

4. To disable Zone 1, press the SYSTEM RESET switch. The Zone 1 yellow LED will light to show

that the zone is disabled.

Note:

The SYSTEM RESET switch toggles disable status for the selected zone.

5. To select the next zone, press the ALARM SILENCE switch.

6. To select the previous zone, press the ALARM ACTIVATE switch.

7. When disable selections are complete, release the TONE SILENCE switch.

If any zone has been disabled, the trouble relay will activate and System Trouble LED will flash.
