Fire-Lite MRP-2002C Agent Release Control Panel - Manual (Page 98)

98 MRP-2002 Series Instruction Manual — P/N 53049:E2 3/7/2013
Operating Instructions Time Functions: Real-Time Clock
4.10 Time Functions: Real-Time Clock
The FACP includes a crystal-based clock that provides time, date and day of week. Time is dis-
played 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, time must be repro-
grammed.
4.11 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
• Two-Stage - Pulses at 20 ppm (pulses per minute) for 3 or 5 minutes and then changes to
Temporal
• Cross-Zone (refer to Cross-Zone for Release Circuit 1 or Release Circuit 2: on page 66)
• Synchronized output for System Sensor, Wheelock, Gentex, Faraday or Amseco - Refer to
“Synchronized NAC Operation” on page 67 for additional information.
4.12 Release Stage/NAC Operation
Outputs programmed as Release Stage NACs indicate the stages of a release operation. There are
three possible release stage methods:
• Release Stage Coded: activation of an input zone programmed to activate an output Releasing
Circuit will start a Pre-discharge delay timer and cause the programmed indicating NAC
output to pulse at a 1/2 sec. on and 1/2 sec. off rate during pre-discharge, turn on steady during
discharge and then 1.5 sec. on and 1.5 sec off after discharge time has expired.
• Release Stage Pre-discharge: activation of an input zone programmed to activate an output
Releasing Circuit will start a Pre-discharge delay timer and cause the programmed indicating
NAC output to turn on steady during discharge, remain on or turn on steady during the
discharge and then turn off after discharge time has expired.
• Release Stage Discharge: activation of an input zone programmed to activate an output
Releasing Circuit will start a Pre-discharge delay timer and cause the programmed indicating
NAC output to remain off. When discharge begins, the NAC will turn on steady and when the
discharge time has expired, the NAC will turn off.
