ADR-741- Addressable Relay Module
The ADR-741 addressable relay module includes a set of dry contact relays for use in cases where it is necessary to perform actions such as electricity disconnect or elevator recall, which are performed via relay. The addressable device communications line (SLC) is galvanically isolated from therelay. The ADR-741 occupies a single address. The address is stored in the module’s nonvolatile memory and can be programmed or verified by using the PROG-4000 Addressable Detector and Accessory Programmer.
The ADR-741 includes an onboard indicating LED that flashes when addressed by the control panel and latches on upon activation. The ADR-741 module is supervised by the control panel and communicates with it via the SLC.
ADR-805 Analog Addressable Switch Interface Module
The ADR-805 switch input module interfaces between the ADR-3000 and a non-powered initiating device such as a presostat, alarm switch, valve switch, sprinkler flow switch, extinguishing gas flow switch, flooding switch, or a supervisory switch. The module is powered by the SLC and does not require 24 VDC input. The module’s input is supervised for short, open, alarm, and normal status. The end-of line device is a 100 K resistor. Configuration jumpers allow the selection of operation mode to be without short supervision (i.e. a short is considered as an alarm or activation) or with short supervision (i.e., a 3.9K resistance is considered an alarm or activation, while a short is considered as a trouble condition). The module is intended to be installed close to the switch it supervises (in the same room or up to 10m) without short supervision; and up to 100m with short supervision. The end of line device is a 100K resistor. The ADR-805 occupies a single address. The address is stored in the module’s nonvolatile memory and can be programmed or verified by using the PROG-4000 Analog Addressable Detector and Accessory Programmer.
The ADR-805 includes an onboard indicating LED that flashes when addressed by thecontrol panel and latches on upon alarm. The ADR-805 module is supervised by the control panel and communicates with it viathe SLC.
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.
