The three-channel module of input-output ADR-823 with a controlled entrance and an exit.
ADR-828 allows to activate 8 uncontrollable exits only for auxiliary indications. It is used for the synoptic panel, alarm lamps, the directing signs, the relay, etc.
ADR-823 is the three-channel entrance/output analog module of management having two output chains (a notification chain about alarm-NAC) and one entrance chain (a chain of the starting device - IDC). This module is intended for use where there is a need for several output and entrance modules for performance of functions of control, the alarm system and automatic fire extinguishing.
ADR-823 works as a link between the address and analog ADR-3000 control panel and ordinary devices of the prevention, the alarm system and activation, such as sirens, stroboscopes, devices of automatic fire extinguishing, pressure relay, valves and the relay of a stream.
ADR-823 operates two 2-hprovodny lines of an exit. The first, NAC A, is an exit with "the return polarity" and activates the additional relay with "dry contacts". Other line, NAC B, is an exit of "the activation level". Each exit has the separate address.
Besides, the device includes a two-wire entrance chain (IDC) intended for connection to the relay of an expense or the button of alarm as the separate address or to the controlling pressure relay with the same address that at NAC A.
ADR-823 has four configurations established by means of crossing points on the module. Logical properties and quantity of addresses are chosen as appropriate.
ADR-823 is connected to the control panel and is operated by him through a loop, receiving 24 V of a direct current from the control panel or the local address power supply unit, it as TPS-34A of the Telefire company.
The module transfers a controlled condition of the connected loads to the control panel. The condition of a chain of loading is transferred as break or short circuit.
ADR-823 occupies from one up to three consecutive addresses (depending on installation of a crossing point), first of which PROG-4000 is programmed.
