How to Program a Release Circuit for an Output Circuit
Note: A 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.
Note: Do not use a Release Circuit for the following: An application requiring ULC Listing; An application requiring
power-limited energy cable.
The following contains information needed to program a Release Circuit for an output circuit (control
module or 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
RELEASE CKT Type Code to
the same Releasing Zone. When the Releasing Zone activates, all outputs associated
with the releasing zone and with the
RELEASE CKT Type Code also activate at the
same time. A 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
• The Abort Switch for R0-R9 (if used) is not active
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 Release Circuit.
2. Select the
RELEASE CKT 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.
