This allows the use of an optional ESL 2500 Keypad for enhanced user interface. One enclosure is used for most system configurations. One cabinet can hold up to 3 expander modules, as well as the necessary standby batteries for either 24 or 60 hour operation. The three (3) expander modules provide up to twelve (12) Class B zones plus one (1) from the BMB for a total panel configuration of thirteen (13) Class B zones. To accommodate system configurations beyond 13 zones, a second enclosure can be installed. For larger installations, the panels can be networked using non-latching zones or the power booster option to provide maximum system flexibility. The versatility of the ESL 2501 Fire Alarm Control Panel is further enhanced by its compatibility with the complete line of ESL smoke detectors, manual fire alarm stations and notification appliances. This allows the assembly of a complete fire alarm system from components produced by a single manufacturer with designed-in compatibility and reliability. See Appendix A for the list of UL Listed compatible devices. 6 SSeennttrrooll 11--880000--554477--22555566 1.2 PANEL EQUIPMENT 1.3 PANEL LISTINGS The flexibility of the ESL 2501 Fire Alarm Control Panel The ESL 2501 Fire Alarm Control Panel is equipped with is derived from its modular design and the array of a “Battery Saving Switching Mechanism” U.S. Patent No.: function modules available for integration into the 2501 5,804,891.

The 2501 (FACP) will automatically perform a 2.9 COMM TEST battery test 10 seconds later. When the system uses a 2500-DAC Digital Alarm Commu- nicator, an automatic comm test is performed every 24 hours as a minimum.

For this reason the National Fire Alarm Code (NFPA 72) requires that fire alarm control panels have both a primary and secondary source of electrical power, usually 2.10 DUAL LRM OPERATION a dedicated 110 VAC branch circuit and battery back-up. If the 110 VAC electrical power is lost AND the system has been operating on battery secondary power for an For localities requiring dual Line Reversal Module extended period of time, beyond that contemplated by the applications, the 2501 FACP can be programmed to code, eventually the battery set will become depleted. transmit separate supervisory and alarm signals. This is Under these conditions the fire alarm control panel can accomplished with the 2500-BELL expansion module. no longer be expected to operate reliably.
