ADR-3000 – System Introduction
Revision 1.10 4 November 2004
4.2.10 ADR-828 Eight-Channel Output Module
The ADR-828 enables activation of 8 unsupervised outputs for auxiliary indications only.
It is used in synoptic panels, indication lights, directing signs, relays, etc. The output can
drive 24 V
DC
lamps or LEDs. The serial resistors required for the LEDs are placed on
board. Use either JP4, or JP5 (LEDs only), but not both.
The ADR-828 should be connected to a
24 V
DC
source from the ADR-3000 or a
TPS-34A Remote Power Supply. The
ADR-828 continuously monitors its power
source and reports any problem such as a
blown fuse, disconnection, or voltage
drop.

The ADR-828 occupies eight consecutive
addresses, the first of which is
programmed by the PROG-4000.
Do not use the ADR-828 for activating
alarm devices that must be supervised.

4.2.11 ADR-823 Three-Channel Input/Output Module
The ADR-823 is a three-channel input/output analog 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 in cases where there is a need
for multiple output and input modules to carry out supervisory, alarm, and automatic
extinguishing functions.
The ADR-823 acts as an interface between an ADR-3000 analog control panel and
conventional warning, alarm, and activating devices such as horns, strobes, automatic
extinguishing devices, pressure switches, valves, and flow switches.
The ADR-823 controls two 2-wire output lines. The first, NAC-A, works as a "changed
polarity" and activates an additional dry-contact alarm relay. The other, NAC-B, works in
level activation mode. Each output has a separate address.
The unit also includes a two-wire input circuit (IDC) intended for connection to a flow
switch or alarm pushbutton as a separate address, or a supervisory pressure switch
sharing the same address as NAC-A.
The ADR-823 has four configurations that are set by
jumpers on the card. The logic properties and number of
addresses are chosen accordingly.

The ADR-823 is controlled by and communicates with
the control panel through an analog SLC circuit and
receives 24 V
DC
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 shorted circuit.

The ADR-823 occupies one to three consecutive addresses (jumper setting-dependant),
the first of which is programmed by the PROG-4000.
Please refer to the ADR-823 technical manual for further details.
