MR-ITM Inspection Test and Maintenance Relays
The ITM - Inspection Test and Maintenance Mode Series Relay provides a convenient, affordable and reliable code compliant solution to successfully accomplish end-to-end life safety system testing, as required by the National Fire Protection Association : NFPA 72 2013 188.8.131.52.
The ITM relay provides the ability to test NAC / Function Control Circuit wiring without needlessly starting or stopping equipment during testing and maintenance. When in ITM Mode the supervised circuit will open to provide a trouble at the fire alarm control panel. All system activation requests will be counted and displayed on the LCD and can be documented without turning on the control circuit. This allows for quick, easy and non-disruptive matching of system input actions to the ITM's device(s) for correlated test and maintenance documentation. The length of the test can be set with the selectable switch between 1, 4 or 8 hours. When testing and maintenance operations are complete the ITM Mode can be switched off manually or will time out thus restoring the system to normal. The ITM Mode is battery powered to eliminate the need for running additional power wires or added current draw.
The ITM ensures a code compliant installation eliminating costly mistakes and improving your efficiency. Make this part of your installation to improve your Inspection Test and Maintenance process.
