Synchronization Output Module
The Synchronization Output Module is an intelligent device that connects a supervised
output circuit to a 24 Vdc riser. The output wiring is monitored for open circuits and short
circuits. A short circuit will cause the fire alarm control panel to inhibit the activation of
the audible/visual signal circuit so the riser is not connected to the wiring fault. Upon
command from the Signature loop controller, the Auto-Sync Output Module connects
the output circuit to the riser input. The output circuit operates polarized audible and
visual appliances that have an adjustable resynchronizing feature.

Input/Output Module
The Input/Output Module is an intelligent device that provides the following
modes of operation:
• Output with monitor input
• Input/programmable output
• Input/direct output

Waterflow/Tamper Module
The SIGA-WTM Waterflow/Tamper Module is a two circuit intelligent module. Circuit 1 is for Class B
normally-open waterflow alarm switches. When the input contact is closed for approximately 16
seconds, an “alarm” signal is sent to the loop controller. Circuit 2 is for Class B normally open dry
contact supervisory and tamper switches. When the input contact is closed, an “active” signal is
sent to the loop controller. Conditions on both circuits are latched at the module.

Isolator Module
The SIGA-IM Isolator Module is an intelligent device that allows part of the Signature data
loop to continue operating in the event of a short circuit. The module can be wired into a
Class A data loop at any point. A maximum of 96 isolator modules can be installed on one
circuit. If a fault occurs, the isolator cuts power to all devices beyond the isolator on the loop.
Once activated, the line fault isolator continuously checks the faulted side of the loop to
determine if the short still exists. When the fault is cleared, the module automatically restores
the entire data loop to its normal condition.

Monitor Module
The SIGA-MM1 is a single-circuit intelligent module that includes a Class B normally-open dry
contact. This is used for monitoring input from devices such as fans, dampers, and doors.
When the input contact is closed, an “active” signal is sent to the loop controller. The active
condition is not latched at the module.
