Honeywell Ademco 5193SD V-PLEX Addressable Photoelectric Smoke Detector

The Honeywell ADEMCO 5193SD is a V-Plex addressable photoelectric smoke detector designed for open-area fire detection with compatible Honeywell security and fire alarm control panels. Featuring two-wire polling-loop communication, automatic drift compensation, and dual red/green LED status indicators, the detector provides individual point identification, alarm reporting, and maintenance supervision. Operating on 7-14VDC, it incorporates a recessed test switch, tamper-resistant mounting base, and field-serviceable optical sensing chamber. The UL 268-listed detector measures 5.3 inches in diameter and supports integration with compatible Honeywell VISTA V-Plex systems.

Honeywell ADEMCO 5193SD V-Plex Addressable Photoelectric Smoke Detector

The Honeywell ADEMCO 5193SD V-Plex Addressable Smoke Detector provides intelligent photoelectric smoke detection for commercial, institutional, and residential fire protection applications using compatible Honeywell V-Plex alarm control panels. Designed for open-area smoke detection, the detector incorporates an optical sensing chamber and advanced microprocessor to identify smoke particles and communicate alarm conditions through a two-wire polling-loop connection. Each 5193SD includes a unique electronic serial number that is enrolled into the control panel, allowing the security system to identify individual alarm points and display detector-specific events. Its low-profile white housing, integrated mounting base, and addressable communication technology support installations where centralized alarm monitoring and individual detector identification are required.

The 5193SD features automatic drift compensation technology that continuously adjusts for gradual contamination within the photoelectric sensing chamber, helping maintain factory-calibrated detection sensitivity over time. When accumulated contamination exceeds the detector's compensation limits, the device communicates a maintenance condition to the connected alarm panel. Two integrated red and green LED indicators provide local visual notification of operating status, alarm activation, and sensitivity trouble conditions. During normal operation, the green LED flashes approximately once every five seconds, while the red LED indicates alarm or maintenance conditions. A built-in recessed test switch allows installers to initiate functional testing, and the optional Honeywell SENS-RDR infrared sensitivity reader provides a method of measuring detector sensitivity in percent-per-foot obscuration without removing the detector from its installed location.

The Honeywell 5193SD operates on a 7-14VDC system voltage range and receives power and communication through the compatible V-Plex polling loop. Manufacturer specifications identify a maximum standby current of 1.2mA at 12VDC with the LED off and 2.8mA at 12VDC with the LED illuminated. The detector uses serial-number-based addressing rather than mechanical rotary address switches, with enrollment performed through the control panel's zone programming interface. For supported Honeywell VISTA configurations, installation programming uses Input Type 06 for a serial-number polling-loop device. The integrated tamper monitoring feature reports detector removal to the control panel, while an optional mechanical tamper-resistant locking arrangement prevents removal from the mounting base without a tool. These features support supervised fire detection installations requiring reliable identification and maintenance reporting.

The 5193SD measures 5.3 inches in diameter and 2.0 inches high with its mounting base installed, with an approximate weight of 6.3 ounces. The included mounting base can be prewired before the detector head is installed, simplifying system installation, servicing, and device replacement. Mounting options include direct surface installation with appropriate fasteners, a standard single-gang electrical box, a 3-1/2-inch or 4-inch octagonal electrical box, or a 4-inch square box with a suitable plaster ring. The detector accommodates 14-22 AWG field wiring through the mounting base terminals. Its operating temperature range is 32 F to 100 F (0 C to 38 C), with an allowable relative humidity range of 0-95% non-condensing. The optical sensing chamber and protective screen are field-serviceable, allowing qualified technicians to clean or replace sensing components according to the manufacturer's maintenance instructions.

The Honeywell ADEMCO 5193SD is designed for compatible V-Plex-enabled Honeywell VISTA control panels, including supported commercial intrusion and combination security/fire configurations. The detector is UL 268 listed for smoke detection and incorporates automatic maintenance reporting, supervised polling-loop communication, and local operational status indication to support professionally installed fire alarm systems. Manufacturer instructions require periodic inspection, functional testing, and a minimum annual cleaning procedure, with detector placement and spacing determined according to NFPA 72, applicable building codes, and the connected control panel's installation requirements. The standard 5193SD is a photoelectric smoke-only detector; the related 5193SDT adds an integrated 135 F fixed-temperature heat sensor. By combining addressable V-Plex communication, automatic sensitivity compensation, removable mounting hardware, and detector-specific supervision, the 5193SD provides a dedicated smoke detection component for compatible Honeywell security and life safety systems.
