1.3 Configuration Jumpers, Resistors & Diodes
•
Battery Charging Circuit (JP1) - To disable local battery charger, cut jumper
JP1 (an external charger listed for fire protective signaling is required).
•
Optional MPM-4F Voltmeter/Ammeter - To enable charger current mea-
surement with MPM-4F, cut JP1 and plug-in MPM-4F connector to the P3
header.
•
Earth Fault Detection (R27)- To disable local earth fault detection, cut
resistor R27. Note that Earth Fault detection is required in Canada.
•
Trouble Supervision (R63, D31, JP2) - These components are used to
configure local trouble reporting through the remote power supply trouble
contact. Refer to the Trouble Supervision section for a complete descrip-
tion.
•
Delay AC Loss Reporting (R76 and R134) - When a Digital Alarm Commu-
nicator Transmitter (DACT) is installed in the FACP, the reporting of an AC
loss condition to a central station must be delayed. With 24-hour battery
standby, cut R134 to delay AC loss reporting for 8 hours. With 60-hour
battery standby, cut R76 and R134 to delay the report by 16 hours.
•
Disable Resettable Power Function for Output Circuit #2 or #4 (R175 and
R176).
Cut R175 to make Output #2 nonresettable power.
Cut R176 to make Output #4 nonresettable power.
1.4 Optional Device MPM-4F Description
The MPM-4F is used for:
•
Monitoring battery/charger voltage (Voltmeter)
•
Monitoring charger current (Ammeter)
The MPM-4F is most commonly required in military installations. It consists of
two analog edge meters (a voltmeter and an ammeter) which connects to the
P3 Header.
The voltmeter measures battery and charger voltage. It is electrically con-
nected across battery terminals TB2.1 and TB2.2. When the battery is
disconnected, the voltmeter measures charger voltage only. Periodically
(approximately 2 seconds every 40 seconds) the FCPS performs a battery test
by disabling the charger. During this period, charger current that is measured
by the ammeter, drops to zero. The voltmeter now only measures the battery
voltage. Battery voltage ranges from 20.4 (low battery) to 27.6 (fully charged).
The ammeter is electrically connected across JP1 and measures current
delivered from the charger to the battery, except for the period during the battery
test. Charger current is normally limited to 250mA. In order to enable the
ammeter, JP1 must be cut.
