The EDWARDS MN-NETLRY4 Network Relay provides four un- supervised input zones and four normally-open relays to and from FireWorks V1.6 or greater over an Ethernet (TCP/IP) network. This module is particularly well-suited for mass notification, life safety applications, and other monitoring or output applications. It is also ideal for interfacing to third-party systems. The MN-NETRLY4’s four input zones may be configured as Alarm, Supervisory, Trouble, or Monitor inputs directly into FireWorks. These can initiate display events and trigger FireWorks logic. The wiring for these zones is limited to 20 ft (6.1 m), and must be mechanically protected in accordance with applicable codes. The four normally-open relays are controlled directly from Fire- Works. These can be programmed to respond to automatic or manual FireWorks commands. Data communication to and from the MN-NETLRY4 is constantly supervised from FireWorks. A fixed IP address is required. The MN-NETRLY4 snaps easily onto the included DIN rail (MN- NRBK1) mounting bracket that can be mounted in an 2-WB, EST3 (on MN-BRKT1), MFC-A, APS(6)(10)A (on MN-BRKT3), or BPS(6) (10)A enclosure. An optional MN-NRMP is also available that will allow two MN-NETLRY4s to be mounted on an MN-BRKT1 in place of an MN-FVPN.
