ESL 1500 Series Fire Alarm Control Panel
Testing and System Checkout
Following installation and programming of the unit, a complete test of the entire system must be conducted to assure proper
operation. NFPA 72, National Fire Alarm Code should serve as the guide. Follow the recommended procedures, restoring all
switches and wiring to normal before proceeding to the next step.
Notify all building personnel and the fire department and monitoring facilities before and after system testing.
After testing all systems and restoring the panel to its normal operating condition, remove, and mount the 1500 Series Operating
Instructions, Appendix C, in a visible position near the control unit. In a household fire warning system, test weekly. Disconnect
the AC power source during testing. If after testing low battery conditions exists, replace the batteries.
Maintenance
Batteries
The 1500 Series control unit uses two sealed lead-acid batteries as the secondary power source. The batteries must be replaced if
the Low Battery LED remains on for more than 48 hours (indicates one or more of the battery cells are dead or the batteries will
not hold a charge). If the batteries are dead, replace with batteries of the same size and electrical rating, with a maximum size of
12V, 12 Amp hours and dimensions of 4” x 4” x 6” (10cm x 10cm x 15cm).
Note: When replacing batteries, always replace both batteries, even if only one appears dead. Typical battery life is 3 to 5
years, depending on usage. See the manufacturer’s specifications for the particular battery used. The battery charging ciruit
drops out if the charge falls below 15 VDC at batteries.
Fuses
The fuse located in the lower left corner of the BMB is provided for overcurrent protection. The fuse can be tested with an
ohmeter or visually inspected. If the fuse is blown, replace with a type 3AG, 1 1/4” (3cm) x 1/4” (0.6cm), 6 Amp Fast Blow fuse.
