Releasing Applications Applications
4.5.4 Connecting a Releasing Device to the Control Panel
Use TB3 (NAC#4), TB4 (NAC#3), TB5 (NAC#2), or TB6 (NAC#1) on the control panel for
NAC⁄Releasing Circuits. Only one listed, compatible releasing device can be installed per NAC.
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 2.5 A. Total current drawn from the power supply cannot exceed 6 A in an alarm
condition (refer to Table A.2, “System Draw Current Calculations,” on page 73). Use
compatible UL-listed 24 VDC appliances only. For more information on compatible
appliances, refer to the Device Compatibility Document.
2. Refer to the XLS140 Programming Manual for instructions on 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 4.5.
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 XLS140
Programming Manual.
!
WARNING:
Do not enable the BACKUP option switch for any of the four Notification Appliance Circuits (NACs) if
they are used for releasing functions!
