Operating Instructions
2nd-Shot Water Switch
4.9 2nd-Shot Water Switch
Following an initial waterflow release, an input circuit with the nonlatching Type Code of 2nd-Shot
Water Switch, when activated, will cause another waterflow release to occur immediately. If a
manual switch is connected to the circuit, an operator has the option to perform any number of
additional waterflow releases following an initial release.
4.10 Detector Functions
Maintenance Alert
i³ smoke detectors will be polled for maintenance and freeze conditions (temperature less than
45^oF) on initial entry into Normal mode. Thereafter, each device will be polled every hour for
freeze and every four hours for maintenance conditions All alarm and system trouble conditions
are annunciated on the control panel’s LCD.
Note: To ensure that the system is functioning properly, the FACP will perform a freeze check five
minutes after the panel is reset, followed by a maintenance check. If there is no freeze or
maintenance condition, the panel will continue to monitor for freeze conditions every hour and
maintenance conditions every four hours.
4.11 Time Functions: Real-Time Clock
The FACP includes a crystal-based clock that provides time of day, date and day of week. Time is
displayed as 12 or 24 hour time with month/day/year and is stored in RAM. Daylight savings time
change-over is programmable and automatic. If both AC and battery are lost, the time must be
reprogrammed.
4.12 Coded NAC Operation
The NAC circuits resident on the control panel main circuit board can be programmed for coded
operation. The available options which can be programmed for coded operation are as follows:
• Steady - Steady output with no pulsing
• March Time - Pulses at 120 ppm (pulses per minute)
• California Code - 10 seconds On, 5 seconds Off
• Temporal Code - Pulses at ½ second On, ½ second Off, ½ second On, ½ second Off, ½
second On, 1½ second Off
• Cross-Zone:
 1st zone of a cross-zoned group in alarm causes programmed NAC output to pulse 1
second on and 1 second off
 2nd zone of a cross-zoned group in alarm causes programmed NAC output to pulse ½
second on and ½ second off - Note: if more than three zones are cross-zoned, the
programmed NAC output will continue to pulse ½ second on and ½ second off for each
subsequent zone in alarm, until the final zone in the cross-zoned group goes into alarm
 all zones of a cross-zoned group in alarm causes the output programmed as a Releasing
Circuit to perform a water release and the programmed NAC output to turn on steady
• Synchronized output for System Sensor, Wheelock, Gentex, Faraday or Amseco - Refer to
"Synchronized NAC Operation" on page 62 for additional information.
