Simplex 4098-5611 Fixed Temp (135F) Heat Detector

The Simplex 4098-5611 is a conventional fixed-temperature heat detector for Simplex two-wire and four-wire detector bases. It uses thermistor-based heat sensing to detect when the local ambient temperature exceeds the fixed alarm threshold, with a built-in red status LED for normal and alarm indication. NOTE: This detector replaces 4098-9612. Use with a compatible current-style 4098 base, such as 4098-5207; older 4098 series bases are not compatible. Key Specifications: Type: Conventional fixed-temperature heat detector Core Function(s): Detects fixed high-temperature heat conditions Loop/Protocol: Conventional IDC; two-wire or four-wire base operation Power: 10.5 to 33 VDC on two-wire bases; 15 to 32 VDC rated voltage on four-wire bases Indicators/UI: Red LED pulses about every 4 seconds in normal condition and stays on in alarm Sensing: 135 F fixed-temperature heat detection Operating Range: 32 F to 122 F; 10% to 95% RH non-condensing Standby Current: Less than 70 uA Alarm Current: 64 mA at 30 VDC, 33 mA at 20 VDC, or 14.5 mA at 12 VDC Mounting: Indoor ceiling or wall mounting with a compatible detector base Compatible Bases & Accessories: 4098-5207 - Two-wire 5-inch base with remote alarm LED connections 4098-5680 - Two-wire 5-inch base with auxiliary alarm relay and remote LED connections 4098-5682 - Four-wire 5-inch base with auxiliary alarm relay contacts and remote LED connections 4098-9830 - Remote LED indicator 2098-9739 - Encapsulated 24 VDC end-of-line relay
