4.8 Connecting Releasing Devices to FCM-1-REL Control
Modules
Typical Connections
Figure 4.11 shows typical connections for wiring a releasing device to the
FCM-1-REL. Refer to the Device Compatibility Document for a compatible releasing devices.
Critical Requirements.
When connecting a releasing device to the FCM-1-REL module, note
the following:
1.
See “Power Considerations” on page 52 for information on monitoring 24 VDC power.
2.
Do not T-tap or branch a Style Y or Style Z circuit.
3.
Only one (1) 24V solenoid or two (2) 12V solenoids in series can be connected to the
FCM-1-REL.
4.
Do not loop wiring under the screw terminals. Break the wire run to provide supervision of
connections.
5.
All applications using the FCM-1-REL are power-limited:
a.
Program the releasing circuit for Type Code REL CKT ULC or RELEASE CKT.

NOTE:
With software version 14.0 or higher ALL new FlashScan Mode SLC releasing applications
require the FCM-1-REL control module. The V-type FCM-1 control module may be used in SLC
releasing applications with software version 14.0 or higher. H-type FCM-1 control modules do not
support FlashScan mode releasing applications with software version 14.0 or higher. Use H-type
FCM-1 for CLIP mode SLC releasing applications.
