MAP to begin interrogating the MATs and CPMs at the remote
site and receiving their responses. When the MAP is done
interrogating the remote site, it commands the modem to hang
up and receives verification from the modem's OFF HOOK
output (pin 40 on the modem is connected to pin 26 of the MAP)
that the master site modem has gone back on hook.
The MAP/44210 modem combination allows remote alarm and
control sites to be polled continuously in any user-specified order
or to be polled a single time at a user-specified time interval.
On the remote site 44210, one or more of the alarm level output
relays (A through D) of a MAT are connected to the MPI inputs
of the 44210. When an alarm occurs at the remote site, the
ground output from the MAT's relay goes to the modem and
turns it on. The modem retrieves the user-specified number to
call, (the phone number unique to the master site), from the on-
board, non-volatile memory and calls the master 44210 with the
alarm data.
For operating information and command syntax for the 460
Alarm and Control System, refer to the 46800-58 MAP Firm-
ware Manual.
