The 15220A, Two Zone, and 15240A, Four Zone, Fire Alarm System Control Unit provides manual, automatic,
and waterflow alarm and supervisory service. Zone #1 may be used as a manual, automatic, or waterflow initiating
circuit or it can be programmed to be used with normally open sprinkler supervisory switches. Zone #2 may be used
as a manual, automatic, or waterflow initiating circuit and can also be programmed to be non-silencable for use with
waterflow switches, if required. The control unit has one signal circuit capable of operating up to a total of 2.5A. of
U.L.listedcompatible signals. Thecontrolunit alsoprovidesup to0.3A.of resetable 19-28VDCpowerfor U.L. listed

that will indicate an open condition or activated annunciator output. The form "C" trouble contact is 21-28VDC
powered for driving a 21-28VDC remote trouble unit or it may be programmed dry for other applications.
The 15213A March Time / Temporal Signaling Module isanoptionalmodule for the15220Aor 15240A FireAlarm
System Control Unit. This module provides programming capabilities for the control unit's signal circuit (Note: This
module doesn't provide two additional signal circuits). Circuit #1 can be programmed for steady, march time or
temporal (code 3) signaling. Circuit #2 is non-silencable, intended for steady operation of strobes or other signals
required to be non-silencable.
