Features  
Available in 8-circuit increments.  
USM-8  
• Compatible with IF632 and IF650  
systems.  
Universal Signal Module  
• Module removal without disturbing field  
wiring.  
• LED annunciation of circuit activation  
and trouble.  
Description  
• Programmable via front panel or PC.  
• Style Y and Z wiring.  
The Universal Signal Module (USM)  
is a multifunctional output module  
that is available in eight-circuit  
increments, designed to provide  
audible and visual annunciation of  
alarm conditions. The USM-8 is  
compatible with both IF632 and  
IF650 systems. The USM-8 can be  
configured for 24 VDC signaling.  
• Requires one MPU bus position.  
• Pairs of circuits can be configured as 24  
VDC steady output, coded, temporal,  
march time, etc.  
• Ground fault detection.  
• Selectable default alarm mode operation.  
• Power-limited circuits.  
The USM-8 includes a display  
module which provides LED annun-  
ciation of circuit activation and  
troubles. The display module has  
space for custom labeling of each  
• Inrush-tolerant circuits.  
• 2.0 Amp output circuits.  
circuit. Each circuit has a tactile switch on the display module for program-  
ming circuit functions and bypass.  
Specifications  
Operation  
Standby current  
36 mA (8 circuits).  
Alarm current  
The Universal Signal Module (USM-8) monitors each circuits value. The  
Fire Alarm Control Panels (FACPs) main CPU processes the information  
to determine the state of each notification appliance circuits wiring and  
condition of the connected devices. If the FACPs CPU detects an off-normal  
reading, the system then executes its programmed response.  
Style Y: 20 mA per circuit.  
Style Z: 42 mA per circuit (plus signal  
load).  
If the FACPs CPU receives a value indicating that there is a ground fault  
condition on the field wiring of the module, the system will annunciate a  
trouble.  
Listings  
If the FACP receives an alarm from one of its connected devices, the  
circuits programmed for response will then activate and the appropriate  
Circuit Active LED will light.  
Listings and approvals below apply to the  
basic Universal Signal Module (USM-8). In  
some cases, certain modules may not be  
listed by certain approval agencies, or  
listing may be in process. Consult factory  
for latest listing status.  
Engineer’s Specifications  
Universal Signal Modules (USMs) shall be provided for emergency evacua-  
tion signaling. The Universal Signal Module shall supply outputs for  
driving audible and visual devices. The same module shall be capable of  
supervising and distributing audio/visual power. Universal Signal Modules  
shall be capable of being wired for either Style Y or Style Z operation.  
Universal Signal Module shall be Gamewell USM-8.
