Potter Electric Signal Co. Us ARM-4 Adder Relay Card

Product Description

The POTTER ELECTRIC SIGNAL CO. US ARM-4 is a 4-output adder relay card designed for use within the Series 5000 fire alarm and waterflow control platform. The card expands relay output capacity in compatible control panels, allowing additional notification, supervisory, or auxiliary functions to be wired and managed from a single system. It is installed by licensed fire alarm technicians and low-voltage electricians working on commercial fire protection systems. Each unit ships individually and mounts within the Series 5000 enclosure to integrate directly with the host panel architecture.

The ARM-4 is suited for commercial fire alarm applications where additional relay outputs are required beyond the base panel capacity. Typical installations include multi-zone waterflow systems, sprinkler monitoring panels, and supervisory signal configurations. The card is part of the Series 5000 product family and is intended for use within that platform. Installers working on waterflow detection and suppression monitoring systems will find this card a direct-fit expansion option for the Series 5000 series.
