1.2 SPECIFICATIONS
Approvals:
• UL Listed 864 Standard for Control Units for Fire Protective Signaling Systems
• Pending: FM
• Pending: MEA approved – NYC Dept. of Buildings
• Pending: California State Fire Marshall (CSFM) approved
• Pending: Fire Protection Bureau (FPB) Chicago
• NFPA 72 compliant
Inputs:
• 120VAC, 50/60Hz, 5.0 Amps Operating Power in Alarm
• 24VDC Battery Backup Connection
• Two (2), 12V or 24V NAC Initiating Circuits (8-33V at 7mA) FWR or DC
• Two (2) “Dry” Contact initiating Circuits
• Accepts two (2) Class “A” or two (2) Class “B” circuit inputs
• Built in battery charger for sealed lead acid or gel type batteries up to a 20 AH.
Batteries larger than 12 AH will not fit inside cabinet, use of an external battery cabinet is necessary.
Outputs:
• NAC outputs are 24VDC, 3.0 Amps each, power limited
• 8 Amps total alarm current for the unit
• Capable of four (4), Class "B" circuits
• Capable of two (2) Class “A” circuits
• Capable of four (4) Class “A” circuits (with optional PS-4CA module)
• Capable of one (1) Class “A” circuit and two (2) Class “B” circuits
• Temporal (Code 3) or constant voltage output generation
• Built-in Wheelock synchronization mode that can be fed to any or all of the output circuits
• Input and output can be synchronized with “IN>OUT SYNC” mode (SM, DSM or 2
nd
PS-24-8MC is
required)
• Audible silence capability
• Filtered and electronically regulated output
• 3.5 Amp auxiliary power limited output with reset capability. (Removed upon AC loss or alarm. Automatic
reset 30 seconds after AC power returns or the alarm condition is over) or 200 mAmps auxiliary power
limited output which remains on during AC loss or an alarm condition.
Supervision:
• Compatible with 12V or 24V (FWR or DC) FACP
• Signaling appliance loops are supervised and steered to either IN1 or IN2
• 2.2K Ohm, 1 Watt (Wheelock Model #MPEOL) End of Line Resistor (EOLR) for supervision of all outputs
• AC loss trouble reported over a separate set of contacts (delay of either 30 seconds)
• All troubles are reported over the common trouble contacts (AC loss can have a delay of 30 seconds or
170 minutes)
• Automatic switchover to standby battery when AC fails
• Thermal and short circuit protection with auto reset
• Input and output status LED indicators
• AC fail supervision
• Battery presence and low battery supervision
• Ground Fault Detection (60K ohms)
