GENERAL DESCRIPTION

Monitor Module, Model EM-1MI, is used to monitor the normally open contacts of an auxiliary device. In addition to monitoring the contact, the device will monitor the wiring to the device for open circuits via an end of line resistor. The module also has on-board short circuit isolators to prevent shorts on the signaling line circuit from disabling more than one device on the intelligent loop. This device is capable of Class A or Class B operation.
