The AE-91 Alarm Expander Card provides one alarm notification appliance circuit which may be wired in a Class A or Class B

configuration (NFPA styles X and Z or W and Y). The module plugs into an expander board (EB-91A) expansion slot and can be

factory programmed for general alarm activation or for selective activation by up to (4) individual detection zones.

%&(*%$

A reverse polarity supervisory current monitors the field loop integrity reporting any short or open in the circuit to the control

panel. When a fault condition occurs the respective LED (yellow) illuminates in conjunction with the system trouble LED and the

system trouble buzzer pulses. Once an alarm input is received, general alarm or individual pre-programmed zones, the circuit

polarity reverses and 24V FWR is supplied to the field output terminals. The Alarm LED illuminates indicating activation. By

pressing the “Silence” button the alarm notification appliance circuit may be silenced. Once the circuit is silenced, pressing the

system reset button “Sys. Rst.” will reset the circuit. If the circuit is not silenced, pressing the “Sys. Rst.” button will reset the con-

trol panel but the Alarm Expander will remain in an alarm state until its “Silence” button is pressed. When wired as a Class A cir-

cuit, all devices will be supplied power in the event of a single open condition in the field wiring. When wired as a Class B circuit,

only the devices before the open condition will be supplied with power. Devices beyond the open condition G9<<>?D operate. This

module is equipped with an “Alarm Test” button that will simulate an alarm output being received by the module.
