Unimode 400 Installation PN 50710A 10/22/97
When connecting a releasing device to an MPS-400, note the following:
1. The control panel provides four NAC/Releasing Circuits (Style Y or Z). Each
circuit can provide 2.5 A. Total current drawn from the MPS-400 cannot exceed
6 A (see Table G-2 on page G-3). Use UL-listed 24 VDC appliances only.
2. Circuits are supervised and power-limited. For more information, refer to the
Device Compatibility Document.
3. 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
Unimode 400 Programming Manual for instructions on setting the Soak Timer.
4. In applications not requiring power-limited circuits – a) End-of-Line devices
(PN REL-2.2K) 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.
Figure 5-15 shows typical connections for wiring a releasing device to an MPS-400:
