Nittan Evolution Addressable Input Module (EV-IP)

The Nittan EV-IP Addressable Contact Input Module is designed to monitor fire contacts such as ventilation control, fire door control, etc.

The EV-IP can be configured as:

• Two spur circuits (Class B) monitoring multiple normally open contacts, with short circuit giving a fault output.
• One loop circuit (class A) monitoring multiple open contacts, with short circuit giving a fault output.

Monitoring Features

EV-IP monitoring features include the following configurable items:

• Identifies all monitored contacts and signals to the CIE the status of monitored contacts and wiring to the contacts.
• Can monitor a single normally closed contact.
  
• Can monitor two Class B spur circuits, or a single class Class A loop circuit.
  
• When two Class B spur circuits are connected, each must be of the same style. A monitored contact going to the active state, on either spur circuit, will cause EV-IP to report the Active State back to the CIE.

LED Status Indicator

An LED reports EV-IP status to the user:

• The LED lights when the contact monitored by the EV-IP has switched to the active (off normal) state.
• The LED when normally off, will pulse when the EV-IP is polled by the EV-IP.
