4.7.5 Connecting Releasing Devices to the FCM-1-REL Control
Module
Typical Connections
Figure 4.13 and Figure 4.13 show typical connections for wiring a
releasing device to the FCM-1-REL. Refer to the Device Compatibility Document for 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:

NOTE:
With firmware version 12.0 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 firmware version 14.0 or higher. H-type FCM-1 control modules do not
support FlashScan Mode releasing applications with firmware version 14.0 or higher. Use H-type
FCM-1 for CLIP mode SLC releasing applications, with firmware version 12.0 or higher.
