Mircom CNSIS-204 Non-Supervised Signal Isolator Module Owner's manual

  • I have reviewed the datasheet for the Mircom CNSIS-204 and CNSIS-202 Signal Isolator Modules. These modules are designed for fire alarm systems, specifically to isolate in-suite audible devices without affecting the rest of the system. The CNSIS-204 provides four non-supervised outputs, and mounts in a standard 4" electrical box. I am ready to answer your questions about their features such as the ability to operate with bells and horns or their installation.
  • What is the purpose of the CNSIS-204?
    How many isolator outputs does the CNSIS-204 provide?
    Does the CNSIS-204 indicate a trouble on the fire alarm control panel if a fault occurs?
    What type of devices does the CNSIS-204 work with?
NON-SUPERVISED SIGNAL ISOLATOR MODULE CNSIS-204
Description
Mircom’s CNSIS-204 Non-Supervised Signal
Isolator Module is designed for installations where
disconnection of, or damage to an in-suite audible
device will not interfere with the ability of audible
devices in other dwelling units, public corridors or
suites to sound on an alarm. The CNSIS-204 mounts
in a 4” square electrical box.
The CNSIS-204 provides four non-supervised
isolator outputs. Under this confi guration, if a short
or open circuit occurs, the isolator disconnects the
audible device from the circuit but it does not indicate
a trouble on the fi re alarm control panel. In this
confi guration, an open circuit in the suite does not
indicate a trouble on the control panel.
Features

Ordering Information
Mircom does not recommend the installation of unsupervised signal circuits. Mircom recommends that
occupants follow proper measures for fi re procedures for their premises.
NOTES:
1. Do not exceed 100mA per suite.
2. For proper system operation refer to detailed installation instructions
provided with control panel and local installation standards.
3. Wiring supervised by the fi re alarm control panel as per code
4. Unsupervised wiring.
5. Refer to the signal device instructions for wiring gauge information.
6. Mircom recommends that all suite isolators should be mounted outside of the suite they are protecting.
