Fire-lite mzb-22 voltage standby: 23VDC 60 mv p-p
I REALIZE THIS DISCRIPTION IS A BIT DIS-JOINTED BUT I COULD FIND LITTLE
Class A or Class 8 for MCB-108. MZB 4. MZB-8. MZB12 and Class 8 only on MCB-114. MZB-22.
Voltage, standby: 23VDC, 60 mV p-p
Current required to ensure alarm: 15mA minimum
Short circuit current: 55 ma msx
End of line resistor: 4.7K, 5%
Maximum resistance per side: 100 Ohms
Maximum total zone resistance: 100 Ohms
2. Compatible. U.L. listed. 2 wire detector available
from fire-Lite, include the following series:
3. Initiating Devices include: Manual itation. heat detectors. smoke detectors. ionization detectors. waterf low
alarm devices. coded manual stations.
4. Inhibit latching circuit by removing diode marked with a 0 from zone card if coded manual stations are connected
5. Use model WFC If the local authority having jurisdiction requires waterflow service without a disable capability.
6. Smoke and Ionization detectors requiring separate 24VDC power can be powered from master control board
Terminal 24 (-) and Terminal 35 (+). See table I for current limitations. Use end of line relay (SDLR-8) to supervise
7. Caution is advised when using 2 wire detector containing supplementary relays or Indicators since their operation
canr be ensured. Example: activation of a manual station. heat detector. or other shorting type detector will
shunt operating current from the 2 wire detectors on the same zone thereby preventing their operation.
8. Detector loop current is sufficient to ensure the alarming of one detector per zone.
9. Detector loop is & Power limited circuit. which may be connected to limited energy cable.
10. Compatible four wire detectos available from Fire-Lite include SD34-24.
