How to Program a Releasing Zone Releasing Applications
A.2.5 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.
Type Codes designed for Releasing Zone inputs (monitor modules).
Type Codes designed for Releasing Zone outputs (control modules and panel NACs).
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.
“abort switch Type Code” on page 74
MAN. RELEASE
(latching)
Provides a manual release through a monitor
module (connected to a UL-listed pull station)
for a Releasing Zone.

75
MAN REL DELAY
(latching)
Provides a manual release with a 30-second
delay (dependent on the FACP Delay setting)
through a monitor module (connected to a
UL-listed pull station) for a Releasing Zone.

76
SECOND SHOT
(latching)
Provides a second manual release through a
monitor module (connected to a UL-listed
pull station) for a Releasing Zone.
“second shot Type Code” on page 78
Type Code What the Type Code does Refer to
REL END BELL Activates a NAC audio or visual device
when releasing circuits shut off.
“release end bell” on page 79
REL CKT ULC Directs outputs to perform a release function
as required by ULC.
“rel ckt ulc Type Code” on page 81
RELEASE CKT Directs outputs to perform a releasing
function.
“release ckt Type Code” on page 83
RELEA. FORM C Directs relay outputs to perform a releasing
function.
“Relea. Form-C Type Code” on page
85
REL AUDIBLE Activates audio or visual devices steady
when releasing starts.
“rel audible Type Code” on page 87
INSTANT RELE Activates non-releasing output (panel NAC
or control modules) with no delay time.
“instant rele Type Code” on page 89
REL CODE BELL Activates audio or visual devices to pulse at
20 ppm (initial zone of a Cross Zone) or 120
ppm (Cross Zone satisfied).Steady on
release.
