The Integlex Multicrest N765 is a scalable analog/addressable fire alarm control panel with a total of 64 nodes in a network. The N765 can be programmed of any combination of smoke detector, heat detector, and modules, a total of 127 (50 ohms impedance) or 255 devices (25 ohms impedance) on a Signal Line Circuit. The N765 may be expanded up to 3 Signal Line Circuits, a total of 765 devices with a sub control unit PCA-N3060-SCU.

The operator interface consists of a 160-character LCD, system status LEDs, a local status buzzer, system control switches, and 4 programmable zone indicators. The LCD and the status LEDs inform the latest system information to the operator. The N765 is secured with a software password to prevent tampering the control panel by unauthorized persons.

The N765 has a 5.0 A power supply with two Notification Appliance Circuits (NACs) and one auxiliary power circuit. The NACs are rated at 3.0 A each and the auxiliary power circuit is rated at 1.0 A. The NACs are programmable and may be configured for NAC codes, strobe synchronization, constant power, or releasing. The strobe synchronization protocol includes Gentex, Wheelock, and Amseco.

The N765 is also listed for releasing of gas suppression systems. The software allows cross zones and counting zones with a total of 64 zones each. The N765 allows to connect a unique gas suppression control unit (FRRU004-GSCU) that is equipped with Auto/Manual changeover switch, countdown timer, two NACs, manual release circuit, abort input circuit, and discharge indicator circuit to make the configuration of gas suppression easy.
