How to Program a Releasing Zone Appendix A: Releasing Applications
NFS-640 Programming Manual P/N 51333:B 10/03/2003 65
Using Type Codes for Releasing Zones
The control panel provides a set of Type Codes designed for releasing applications for inputs and
outputs. This section details how to program each of these Type Codes.
Note: Do not assign Releasing Type Codes to Panel Circuits, with the exception of the audible Type Codes REL END
BELL and REL AUDIBLE.
Type Codes designed for Releasing Zone inputs (monitor modules).
Type Codes designed for Releasing Zone outputs (control modules and panel NACs, and Panel Circuits
with the audible Type Codes REL END BELL and REL AUDIBLE).
Type Code What the Type Code does Refer to
ABORT SWITCH
(tracking)
Provides an abort function through
a monitor module (connected to a
UL-listed abort station) for a
Releasing Zone.
“How to Program an Abort
Switch” on page 66
MAN. RELEASE
(latching)
Provides a manual release through
a monitor module (connected to a
UL-listed pull station) for a
Releasing Zone.
“How to Program a Manual
Release Switch” on page 67
MAN REL DELAY
(latching)
Provides a manual release with a
10-second delay through a monitor
module (connected to a UL-listed
pull station) for a Releasing Zone.
“How to Program a Manual
Release Delay Switch” on page 68
SECOND SHOT
(latching)
Provides a second manual release
through a monitor module
(connected to a UL-listed pull
station) for a Releasing Zone.
“How to Program a Second Shot
Switch” on page 70
Type Code What the Type Code does Refer to
REL END BELL Activates a NAC audio or visual
device when releasing circuits shut
off.
“How to Program a Release End
Bell Circuit” on page 71
REL CKT ULC Directs outputs to perform a release
function as required by ULC.
“How to Program a ULC Release
Circuit” on page 72
RELEASE CKT Directs outputs to perform a
releasing function.
“How to Program a Release Circuit
for an Output Circuit” on page 73
RELEA. FORM C Directs relay outputs to perform a
releasing function.
“How to Program a Release
Form-C Circuit” on page 74
REL AUDIBLE Activates audio or visual devices
steady when releasing starts.
“How to Program a Release
Audible Circuit” on page 75
INSTANT RELE Activates non-releasing output
(panel NAC or control modules)
with no delay time.
“How to Program an Instant
Release Circuit” on page 76
REL CODE BELL Activates audio or visual devices to
pulse at 20 ppm (Delay Timer
activation) or 120 ppm (Cross Zone
activation).
