Figure 6 ACK and PFAIL Input Circuit
Power Fail Input
If a power failure status is available from the external power supply, it
can be connected between the PFAIL input and ground and then used
to generate an alarm. The power fail signal must be a relay contact or
open collector; do not apply voltage to the PFAIL input. In the
programming for this alarm, the normal state can be set for either open
or ground.
Output Relays
If external equipment is to be notified of system status conditions, the
output relays can be used. Each of the two relays can be programmed
to indicate one of these status conditions:

New alarm exists

Any alarm exists

Acknowledge received

Error condition
Any of the 8 groups can be included in the status for each type.
Connectors - Programming
DB9
This DTE RS232 programming port is used to:

Transfer configuration data containing the programmed
operating parameters

Transfer voice data with the user programmed messages

Transfer vocabulary data containing the 'canned' voices used
by the system

Upgrade files for flashing new code into the modules

Monitor current system conditions
