D.2.13 Auxiliary Control Relay Functions
You can also use control relays for releasing applications. To do so, set control modules
for dry contact operation (refer to Table 24 on page 83). Control relays can be
programmed for different functions, just like warning sounders as described above.
Also, you can map RTM-8 modules or ACM-8Rs to control panel software zones to
provide control functions.
D.2.14 ACS Annunciation
ACS point annunciation of releasing functions can be done by annunciating any of the
software zones described above, including zones Z91, Z92, Z93, and Z94. To set ACS
annunciation of individual detectors, assign each detector to a separate software zone
and annunciate the zone.
D.2.15 Deluge/Pre-Action Release
Installing Deluge and/or Pre-Action applications requires a wiring configuration that
maintains a minimum voltage on releasing circuits. To calculate maximum allowable
resistance, use the formula shown in Figure 144:
Figure 144 Formula for Calculating Maximum Resistance
Note:
• Factory Mutual requires 90 hours of standby power, Style D (Class A) wiring on all
Initiating Device Circuits and V
D
= 0.2 VDC.
• For NFPA 13 and 15 applications, the soak timer must be disabled.
• For NFPA 16 applications, the soak timer may be set to 10 or 15 minutes.
• For UL-listed and FM-approved Solenoid Release Valves, refer to the Device
Compatibility Document.
• Do not program an abort switch for deluge/pre-action applications.
D.3 Connecting Releasing Devices
This section contains typical wiring diagrams for the following releasing applications:
• Connecting a releasing device to a control panel through a control module (Figure
145 on page 154)
• Connecting the control panel to an agent release abort station (Figure 146 on page
155)
