ADR-723 Addressable Hige-Power Output Module

The ADR-723 is a three-channel input/output control module that contains two output circuits (NAC – Notification Alarm Circuit) and a single input circuit (IDC – Initiating Device Circuit). This module is intended for use wherever there is a need for multiple output and input modules to carry out supervisory, alarm, and automatic extinguishing functions. The ADR-723 acts as an interface between an ADR-3000 addressable control panel and conventional warning, alarm, and activating devices such as sounders, strobes, automatic extinguishing devices, pressure switches, valves, and flow switches. The ADR-723 controls two 2-wire output lines. Both outputs are “reversed polarity” outputs. Output A activates an additional dry-contact relay. Additionally, the unit includes a two-wire input circuit (IDC) intended for connection to a flow switch or push button alarm as a separate address, or a supervisory pressure switch sharing the same address as NAC A. The ADR-723 has four

configurations that are set by jumpers on the module. The logical properties and number of addresses are selected accordingly. The ADR-723 communicates and is controlled by the control panel through the SLC circuit and receives 24 Vdc from the control panel or a local addressable power supply such as Telefire’s TPS-34A. The module reports supervision status of the connected loads to the control panel. Load circuit status is reported as open or short circuit. The ADR-723 occupies one to three consecutive addresses (jumper-setting dependent), the first of which is programmed by the PROG-4000.
