Releasing Applications
Applications
Circuit Requirements.
When connecting a releasing device, note the following:
1. The control panel provides four NAC/Releasing Circuits (Style Y or Z). Each circuit can
provide 1.5 A. Total current drawn from the power supply cannot exceed 7.4 A in an alarm
condition (refer to Table 6.2, “System Draw Current Calculations,” on page 52). Use
compatible UL-listed 24 VDC appliances only. For more information on compatible
appliances, refer to the
Device Compatibility Document
.
2. Refer to the Releasing Applications appendix in the
IQ-318/E Programming Manual
for
configuration details (such as setting the Soak Timer).
3. For applications using power-limited circuits:
a) Use an in-line supervisory device (P/N REL-2.2K) with control panel releasing circuits.
Connect the End-of-Line device as shown in Figure 4.7.
b) Program the releasing circuit for Type Code REL CKT ULC.
c) Circuits are supervised against opens and shorts.
4. For applications not requiring power-limited circuits –
a) If the application does not require supervising the releasing device against shorts, in-line
supervisory devices (P/N REL-2.2K) are not required.
b) In non-power-limited applications, program the releasing circuit for Type Code
RELEASE CKT.
c) Limited energy cable cannot be used to wire a non-power-limited releasing device circuit
d) Maintain a 0.25 inch (6.35 mm) spacing between the non-power-limited releasing circuit
device wiring and any power-limited circuit wiring.)
5. The releasing circuit must be programmed with a releasing type code listed in the
IQ-318/E
Programming Manual
.

Figure 4.9 Releasing Circuits (Option 2)
NOTE:
As per UL 864 9
th
Edition, a supervisory signal must be indicated at the panel whenever
a releasing circuit is physically disconnected. Use a monitor module to monitor dry contacts off the
switch. See 4.11.
