Releasing Applications Applications
4.7.2 Programming
The control panel supports up to ten releasing software zones. You can map these zones to activate
Control Panel releasing outputs and FCM-1 modules. Program the FCM-1 module for the
appropriate type code according to the chart below:
For more information, refer to the IQ-636X-2/E Programming Manual.
4.7.3 Connecting a Releasing Device to the Control Panel
Use TB6 (NAC#4), TB7 (NAC#3), TB8 (NAC#2), or TB9 (NAC#1) on the control panel for
NAC⁄Releasing Circuits. The releasing circuit must be supervised and use listed, compatible
releasing devices; see Figure 4.8–Figure 4.10 (page 52).
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 A.2, “System Draw Current Calculations,” on page 61). 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-636X-2/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.
Type Code: RELEASE CKT
• For use in UL applications.
• Do not use REL device at the solenoid.
• Cannot use power-limited wiring.
• Supervised for open circuit only.
• Supervised for power loss with power-
supervision relay.
Type Code: REL CKT ULC
• For use in UL or ULC applications.
• Requires REL device at solenoid.
• Power-limited wiring.
• Supervised for open circuit and shorts.
• Supervised for power loss with power-
supervision relay.
WARNING:
Do not enable the BACKUP option switch for any of the four Notification Appliance Circuits (NACs) if
they are used for releasing functions!
