When connecting an N-ARA-10, note the following:
1. For releasing applications, use an end-of-line device (PN REL-47K) with the CMX
module. Use an end-of-line device (PN REL-4.7K) with the control panel
releasing circuit (one of the four Notification Appliance Circuits).
2. All wiring for releasing circuits is supervised against open and shorts.
3. Connect the end-of-line device as shown Figure 5-22.
4. Program the module or NAC for type code “Rel Ckt ULC.”
5. For NFPA 13 and 15 applications, disable the Soak Timer (Soak=0000); for NFPA
16 applications, set the Soak Timer (0600-0900 seconds). Refer to the AFP-300/
AFP-400 Programming Manual for instructions on setting the Soak Timer.
6.
In applications not requiring power-limited circuits
– a) ELRs (PN REL-47K) are
not required; however, the releasing device circuit is not supervised against shorts;
b) Limited energy cable cannot be used for wiring of a releasing device circuit;
c) Maintain a 0.25 inch spacing between the releasing circuit device wiring and any
power-limited circuit wiring; and d) Program the releasing circuit for type code
RELEASE CKT.
