Operator’s Manual
4.2 Operation
The operation of the status monitor is automatic and carries out its functions without
the direct intervention of the operator. The purpose of the status monitor is to indicate
the operating conditions of the CPR power supply. There are three levels of status
monitoring:
LEVEL ONE is used to indicate locally (at the power supply) only (see Figure 4.3-1). This
can be a combination of the external cabinet LED indicators and/or the LED’s on the CPR
power supply. This level is NOT compatible with transponder devices. The information avail-
able in addition to the information displayed on the front of the CPR power supply is as fol-
lows: A)Weak battery string indicators (located on the Communicator module - refer to Figure
4.3-1); B) Normal operation, Standby operation, and Alarm condition indicators (with the ex-
ternal cabinet LED’s). The weak battery indicators can be reset by pushing the Battery LED
Reset button, located on the front of the CPR power supply. Refer to Figure 4.1-1
LEVEL TWO allows for remote status monitoring with access to additional, more detailed in-
formation (see Figure 4.3-2). Level Two is essentially the same as Level One with the addi-
tion of a DB-9 connector located on the front of the communication module. The DB-9 con-
nector is used to indicate remotely via a third party transponder device. The data available is
in RS-232 format. Additionally, information can be obtained through the DB-9 connector with
the use of a PC using a software program called FailSafe, available from Alpha Technolo-
gies. A customer-supplied PDA device may also be connected to this port using application
and instructions available from Alpha Technologies. A telephony modem may also be con-
nected to the RS-232 port. Be sure to disable “hardware handshaking” for proper operation
of the modem in this application.
LEVEL THREE allows for remote status monitoring similar to Level One and Two with the
DB-9 connector replaced by an F-81 style, 75-ohm, RF connector (see Figure 4.3-3)*. Level
Three is used to indicate remotely via an internal (inside the communicator module) RF
transponder. The F-81 connector is used to make the connection between the transponder
and the CATV Network.
*Contact Alpha Technologies for information on compatibility with other popular status moni-
toring systems.
Note: All three levels have the ability to provide local indications. Each level uses a different
communication module, mounted on the left side of the CPR module (see Figure 4.1-1).
