FSUIM Universal Interface
Module Installation Sheet
Description
The FSUIM Universal Interface Module provides five common control
switch inputs and nine common relay outputs. Typically, the FSUIM is
used in a graphic annunciator connected to an F-series fire alarm
control panel.
LEDs provide visual indication when a relay is energized.
The FSUIM is shipped with a plastic snap track for mounting in an
MFC-A cabinet.
Installation
Install the FSUIM according to the instructions provided below. The
FSUIM will not operate properly until detected by the control panel.
You can only install one FSUIM per system.
For more information, refer to the technical reference manual listed
inside the control panel door.
Caution: Make sure all power is disconnected from the panel before
installing. Observe static-sensitive handling practices.
To install the FSUIM:
1. Mount the snap track in the MFC-A cabinet as shown in Figure 1.
You can also mount the snap track vertically, if required.
2. Insert the bottom edge of the FSUIM into the snap track then press
the top edge in until it snaps into place.
3. Wire the FSUIM as shown in Figure 1. Verify that all wiring is free
of opens, shorts, and ground faults.
Legend for Figure 1
(1) All wiring is supervised and power-limited unless noted otherwise.
(2) Only the trouble relay and power relay are energized when power
is applied.
(3) AUX power supplied by the control panel can’t exceed 0.5 A. If
more than 0.5 A is required, you must use a power-limited and
regulated 24 VDC auxiliary/booster power supply that is UL/ULC
Listed for fire protective signaling systems.
(4) If powered from an external supply, the supply must be installed
in the same room as the control panel and their 24 VDC
commons (−) wired together.
(5) Relay outputs are not supervised and do not provide current
limiting. Connect relays only to power-limited sources.
(6) Use momentary switches only.
(7) Mount LEDs and switches in separate cabinet located in the same
room as the FSUIM.
