Each model is built on a Basic Master Board with the option to expand zones using Zone Expander Modules, allowing up to 5 total zones. Initiating circuits support two-wire or four-wire detectors in Class A or Class B wiring configurations. The panel supervises all initiating and indicating circuits for faults and provides features such as walk-test mode, alarm verification, and supervisory or waterflow monitoring on designated zones. Housed in a steel enclosure with lockable door, the panel supports auxiliary power, standby batteries, and additional modules for remote annunciation, digital communications, and local energy connections. The ESL-1500 meets UL fire alarm standards and is approved for use in various jurisdictions. Key Features: Multiple Zone Options: Available in 1, 3, or 5 zone models, expandable with modules. Alarm Verification: Reduces nuisance alarms with selectable verification for smoke detectors. Walk-Test Mode: Allows installers to test devices without resetting the entire system. Supervised Circuits: Both initiating and indicating circuits monitored for faults and ground issues. Device Compatibility: Supports two-wire and four-wire smoke detectors, heat detectors, and manual stations. Modular Expandability: Accepts zone expanders, relay modules, remote annunciators, and communicators. Supervisory Monitoring: Zone 2 programmable for sprinkler supervisory devices and waterflow. Auxiliary Power Supply: Provides 24 VDC for system devices with standby battery backup capability. Durable Construction: Steel cabinet with hinged, lockable door for secure installation. Code Compliant: UL-Listed and approved for fire protection installations. The ESL-1500 delivers the reliability, supervision, and expandability needed for modern conventional fire alarm systems.
