Programming Releasing Zones

D.2.9 Rel Ckt ULC

Description

:

Rel Ckt ULC

is a type code assigned to an SLC control module. A device programmed with this type code activates a releasing solenoid or other releasing device as follows:

• when an initiating device programmed to the same zone activates (two devices if cross-zoning selected);

and

• when the delay timer (if used) expires;

and

• when no Abort Switch (if used) is active.

Installation

: All wiring to the releasing device, and the releasing device itself, is fully supervised and suitable for use with limited energy cable. You can program multiple

Release CKT

type codes to the same releasing zone so all devices activate when the same releasing zone becomes active.

D.2.10 Release Ckt

Description

:

Release Ckt

is a type code that operates similar to

Rel Ckt ULC

—except a

Release Ckt

device is only supervised for open circuits and ground faults. A device programmed for Release Ckt is not supervised for short circuits.

Installation

: All wiring to the releasing device, and the releasing device itself, is fully supervised. You can program multiple

Release CKT

type codes to the same releasing zone so all devices activate when the same releasing zone becomes active.

Restrictions

: Do not use this type code with the following:

• Applications requiring ULC listing or with limited energy cable.

• REL-47K (control module) with a Release Ckt type code.

D.2.11 Initiating Devices

Initiating devices include the following:

• FST intelligent heat detectors, FSP or FSI intelligent smoke detectors, or

• Conventional detection devices which are UL-listed for initiating applications and connected to monitor modules.

Multiple initiating devices can be used for the same releasing hazard by mapping them to the same releasing zone. Factory Mutual and certain local authorities having jurisdiction (LAHJ) require use of redundant wiring (NFPA 72 Style 6 or Style D) for the initiating devices in releasing applications.

D.2.12 Warning Sounders

Warning sounders are audible devices (such as bell and horns) that connect to

Notification Appliance Circuits or to control module circuits. Multiple Notification

Appliance Circuits may be activated by the same releasing hazard.

Note: If your application requires coded signals (such as Temporal, March Time, and so on), connect the warning sounder through one of the four panel Notification Appliance

Circuits—not a control module circuit.

Program a warning sounder to activate as follows:

• To activate when the delay timer starts, when the releasing device activates, or both: map the control module to the releasing zone (Z91, Z92, Z93, or Z94). If also selecting the releasing zone for cross zoning, a warning sounder only activates when two releasing zones go into alarm (refer to Table 55 on page 149). Unlike releasing solenoids, however, warning sounders do not wait for the delay timer.

• To activate when any of the initiating devices activate: map the control module to a separate zone (not Z91, Z92, Z93, or Z94) that is also mapped to all initiating devices of the hazard.

Releasing Applications

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:

V

D

R max

=

I

S

Where:

R max

= maximum allowable resistance of wiring

V

D

= allowable voltage drop

I s

= solenoid current

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)
