For the PDRP-1002E: 220/240 VAC, 50 Hz, 0.6 amps
Wire size: minimum #14 AWG with 600V insulation
Battery (lead acid only)
Maximum Charging Circuit: 27.6V, 1.5 amps
Maximum Battery Capacity: 15 AH. (Batteries larger
than 12 AH require NOTIFIER #BB-17 or other UL
listed external battery cabinet.)
Initiating Device Circuits
Power-limited circuitry
Operation: Class A (Style D)/Class B (Style B)
Normal Operating Voltage: 24 VDC (ripple = 1.0V peak-to-peak)
Alarm current: 15 mA minimum
Short circuit current: 40 mA maximum
Maximum detector current in standby: 2 mA (max) per zone
Maximum loop resistance: 200 ohms
End-of-line resistor: 4.7K, 1/2-Watt (NOTIFIER part # 71252, UL listed)
Detector loop current is sufficient to ensure operation of one alarmed detector per zone.
Supervisory current: 5 mA (including end-of-line resistor)
Notification Appliance and Releasing Circuits
Power-limited circuitry
Maximum allowable voltage drop due to wiring: 2 VDC
Normal Operating Voltage: 24 VDC
Total current available to all external devices: 2.25 amps
Maximum signaling current per circuit: 1.5 amps
End-of-line resistor: 4.7K, 1/2-Watt (NOTIFIER part # 71252, UL listed)
Alarm and Trouble Relays
Dry Form-C contacts rated: 2.0 amps @ 30 VDC (resistive), 0.5 amps @ 30 VAC
(resistive). All relays must be connected to a power limited power supply.
Four-wire Smoke Detector Power
Up to 200 mA is available for powering 4-wire smoke detectors.
Maximum ripple voltage: 1.0 V p/p
Non-resettable Power
Total DC current available from this output is up to 200 mA (subtracted from 4-wire
smoke power).
Maximum ripple voltage: 1.0 V p/p
RMS Regulated Power
Total DC current available for powering external devices is 0.5 amp (subtracted from
2.25 amps available to notification appliance circuits).
Maximum ripple voltage: 100 mV p/p
