How to Program a ULC Release Circuit
Note: A ULC Release Circuit with this Type Code requires the following selections: A Releasing Zone selection (R0-
R9); An output circuit mapped to the same Releasing Zone; Switch Inhibit selected; Non-Silenceable; No Walk Test.
The following contains information needed to program a ULC Release Circuit for a control module or a
NAC
.
Description A control module or a NAC used to activate a releasing solenoid or other releasing
device. You can also program multiple outputs with the
REL CKT ULC Type Code to
the same Releasing Zone. When the Releasing Zone activates, all outputs with the
REL CKT ULC Type Code also activate at the same time. A ULC Release Circuit
activates when:
• An initiating device programmed to the same Releasing Zone activates
(two devices if using the Cross Zone option)
• The Delay Timer for R0-R9 (if used) expires
• No Abort Switch for R0-R9 (if used) is active
A ULC Release Circuit —and all wiring to the release device—is fully supervised
and usable with power-limited energy cable.
How to
program
1. Select a control module or a NAC (refer to “How To Modify Or Delete A Point
(2=
POINT)” on page 21) that you want to use as a ULC Release Circuit.
2. Select the
REL CKT ULC Type Code, as shown in the following example (control
module shown).
3. Select the Releasing Zone (R0-R9) for your releasing application.
4. Press the
ENTER key to save, then press the ESC key two times to return to the
Program Change screen.

For example, all control modules programmed with the REL
CKT ULC Type Code activate simultaneously with other outputs
programmed for R5 (B01, B02).
