D.2.9 Rel Ckt ULC
Description
:
Rel Ckt ULC
is a type code assigned to a control module, or one of the
four control panel NACs. 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-4.7K (control panel output) or 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 (refer to Figure 145).
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
