Power-limited circuit
1.3 Controls and Indicators
LCD Display
The MS-9200 uses a 40-character (2 lines X 20
characters) high viewing angle LCD display with a
character height of 3/16". The display includes a
long-life LED backlight that remains illuminated. If
AC power is lost and the system is not in alarm, the
LED backlight will turn off to conserve batteries.
LED Indicators
LED indicators are provided to annunciate the following conditions:
• AC Power (green)
• Fire Alarm ((red)
• Supervisory (yellow)
• Alarm Silence (yellow)
• System Trouble (yellow)
• Ground Fault (yellow) - located on bottom of main circuit board (refer to figure on page 7)
1. Total current for special purpose power, nonresettable power, 4-wire smoke power and two NACs must not exceed 6.0 amps.
Total external system current in excess of 3.6 amps requires XRM-24E Transformer and 12 AH or 18 AH batteries, not 7.0 AH.
2. For power supply calculations, refer to Appendix A.
3. Total current for resettable 4-wire smoke detector power and nonresettable power must not exceed 600 mA.
