Technical Specifications
All specifications are typical characteristics measured under nominal conditions at 25° C, unless otherwise specified.
System Power Requirements
MP-12/24 Operating voltage: 120 VAC, 60 Hz (standard).
MP-12/24 Current Draw: 0.5 A (maximum).
MP-12/24E Operating voltage: 220/240 VAC, 50/60 Hz
MP-12/24E Current Draw: 0.250 A (maximum).
Standby battery:
Voltage: (MP-12) 12 VDC; (MP-24) 24 VDC
Capacity: 2.5 to 7.0 AH (dependent on external loading).
Detection Loop
Operation: Style B (Class B).
Voltage: (MP-12) 8.6 to 12.2 VDC, ripple 0.65 Vp-p. (MP-24) 18 to 26.2 VDC, ripple 2.0 Vp-p.
Current required to ensure alarm: 20 mA (minimum)
Short circuit current: 40 mA - 10 mA
Supervision current: 5 mA
ELR: (MP-12) 2.2 K, 0.5 W; (MP-24) 4.7K, 0.5 W
Max resistance per side: 100 ohms.
Max total zone resistance: 200 ohms.
Two-wire Smoke Detectors
Head voltage, standby: MP-12, 11 VDC; MP-24, 23 VDC.
Total standby head current per zone: 2 mA peak
Minimum head current to ensure alarm: 20 mA
Maximum alarm current supplied to initiating devices, per zone: 40 mA - 10 mA.
Main Notification Appliance (bell) Circuits
Activation: By any zone alarm
Disconnect: By DISABLE switch
Operation: Style Y (Class B).
Notification Appliances: Use polarized, UL Listed, Notification Appliances with a minimum rated voltage
range of 9-15 VDC on MP-12 and 18-30 VDC on MP-24. Refer to the Fire•Lite Device Compatibility Docu-
ment for a listing of compatible devices.
Nominal output voltage: (MP-12) 12 VDC; (MP-24) 24 VDC.
Output is
Special Purpose Power (full wave rectified DC, unregulated and unfiltered).
Output current: Total current to all external Notification Appliances cannot exceed: (MP-12) 1.0 A; (MP-24)
0.75 A.
External Device Power
Regulated DC output: Resettable power primarily for four-wire smoke detectors and/or other low power
electronic devices. Maximum current available: 100 mA
Note: Size standby battery to include external loading.
Nominal voltage: (MP-12) 12 VDC; (MP-24) 24 VDC.
Battery Charger
Float type, turned off during alarm.
Float voltage setting: (MP-12) 13.8 VDC; (MP-24) 27.6 VDC. Automatic current limiting.
Note: Since battery charger is pulsed on and off, the charger output cannot be read with a voltmeter when
battery is not connected. A typical voltmeter would read approximately 8.5 V on the MP-12 and 16.5 V on the
MP-24.
