Multipoint Scanning Alarm System

Multipoint Scanning Alarm System

Many gas detection applications require multiple sensing locations to provide adequate area protection for plant

personnel. Signals from a variety of field measurement sites are often transmitted to a central location where display

and alarming functions are needed. ATI's Series Cl4 Scan Alarm) Receiver provides a versatile central monitor that can

be configured to meet most multipoint gas detection applications.

Features

• Monitors up to 16 analog 4-20 mA inputs

from remote transmitters.

• Provides 24 VDC power for up to 16

loop-powered toxic gas transmitters or 12 3-wire

combustible gas transmitters.

• Two line alphanumeric LCD provides

sequential display of each channel and the

alarm status for that channel. Display locks

on any channel that goes into alarm.

• Remote alarm reset input.

• Two programmable alarm setpoints for each

analog input plus a trouble alarm for each

channel.

• Six assignable SPDT alarm relays in standard

configuration, with expansion for up to 36

total relay outputs. One output relay is

factory set for global alarm and one is set for

system failure.

• Battery backup module available to operate

the system for up to 30 minutes with the

maximum number of combustible gas

transmitter inputs (worst case).

• Standard RS-232/485 serial interface allows

all configurations to be set up by computer

and alarm events to be automatically

monitored by computer. Up to 32 separate

monitors can be connected to a single

RS-485 communication link.

• Standard NEMA 4X wall mount enclosure.

Optional panel mount configuration.
