EXAMPLE
Consider an ARIES Control Unit that is monitoring a waterless extinguishing system for a data-
processing center. The automatic detection system consists of ten (10) Model PSD-7152
Photoelectric Detectors and ten (10) Model CPD-7052 Ionization Detectors, crossed-zoned in
such a manner that the activation of at least one photoelectric detector and one ionization
detector is required to automatically discharge the waterless extinguishing system. The initiating
system also includes eight Model AI Monitor Modules for manual-release, abort, and sprinkler-
supervisory requirements. Four (4) Model AO Relay Control Modules are being utilized for
remote control function such as airflow shutoff and power shutdown. One AO activates at pre-
alarm, two additional AOs activate at pre-release, and the final AO activates upon extinguishing-
system discharge.
Six (6) Model NS-24MC combination horn/strobes (75 cd) are used for occupant notification. The
horns are activated during the pre-alarm condition. The strobes are activated at pre-release, and
remain on until the system is reset.
A Model 486500-01 Control Head is being used to activate the waterless extinguishing system.
A pre-action sprinkler system, controlled by an FM-Approved, Group B solenoid, will be activated
concurrently with the waterless extinguishing system.
The system is using a Model RDCM Remote-Display Module for additional event annunciation.
The standby-battery calculation is shown in Table A-2.
