About this product .

The Honeywell HM-PSE-S2 is an analog addressable photoelectric smoke detector designed for intelligent Morley-IAS fire safety systems. Operating on light-scattering optical detection principles, the unit rapidly identifies smouldering and flaming fires while internal smoothing algorithms reliably suppress false alarms triggered by dust, steam, or airborne particles.
Engineered for low power consumption across addressable loops, the detector operates from 15 V DC to 32 V DC with a quiescent standby current of 200 µA at 24 V DC without communication, or 300 µA with active 5-second LED polling. In alarm state, current draw rises to 3.5 mA to illuminate dual integrated LEDs that provide high-visibility 360-degree annunciation, supported by an auxiliary 22.5 V DC remote output rated up to 10.8 mA.
Constructed from resilient polycarbonate/ABS (PC/ABS) blend finished in ivory, the device is built to maintain structural integrity across harsh indoor commercial environments. The installed assembly measures 102 mm in diameter and 52 mm in height when seated on a standard B501AP base, with screw terminals accommodating wiring cross-sections up to 2.5 mm².
Addressing is configured manually via two decimal rotary decade switches (01 to 99) located on the device rear, eliminating the need for dedicated electronic hand-held programming tools. The detector fully integrates with Morley-IAS DXc, ZX, and PL series fire alarm control panels, adding a minimal loop resistance of typically 20 mΩ when installed with the B501AP base.
Compliant with rigorous European fire safety norms, the HM-PSE-S2 holds certification to EN 54-7 for point smoke detectors and EN 54-17 for short-circuit isolators, alongside RoHS conformity. It is typically specified for commercial offices, data centres, healthcare institutions, hotels, educational facilities, and industrial warehouses.
For ongoing facility operations, the detector incorporates built-in chamber drift compensation to automatically readjust sensitivity thresholds against environmental dust accumulation. Periodic maintenance is simplified by cleanable, washable optical chamber filter elements that extend operational service life without premature sensor replacement.

System and Hardware Compatibility

Fire Alarm Control Panel Interoperability

The Honeywell Morley-IAS HM-PSE-S2 addressable photoelectric smoke detector is an integral component of the Morley-IAS S200A Series intelligent detector family. It is engineered for direct communication and integration with Honeywell Morley-IAS intelligent fire alarm control panels, including the DXc Series, ZX Series, and PL Series (such as the PL-1000). The detector operates across an analog addressable loop voltage range spanning from 15 V DC to 32 V DC, providing continuous bidirectional data transmission and status monitoring back to the host panel.

Base Interface and Wiring Specifications

Mechanical and electrical connection to the signaling line circuit (SLC) requires the standardized Honeywell Morley-IAS B501AP plug-in base. When seated within the B501AP base, the detector introduces an additional loop resistance of typically 20 mΩ (with an engineered maximum limit of 30 mΩ), allowing system designers to accurately calculate overall loop voltage drop across extended circuit lengths. The base screw terminals accept field wiring conductors up to a maximum wire gauge of 2.5 mm², accommodating standard industrial fire-resistant paired or shielded cable runs.

Loop Power and Standby Current Budgeting

For accurate loop loading and battery standby calculations across Morley-IAS addressable loops, system engineers must factor the following electrical consumption values at a nominal 24 V DC supply:

Standby Current (No Communications): 200 µA at 24 V DC.
Standby Current (With Communications): 300 µA at 24 V DC with LED blink polling enabled at 5-second intervals.
Active Alarm Current: 3.5 mA at 24 V DC to power the onboard dual integrated LEDs for 360-degree status indication.

Auxiliary and Remote Indicator Integration

The HM-PSE-S2 features dedicated remote annunciator output terminals designed to drive external visual indicators. When powered at a standard 24 V DC loop voltage, the remote output delivers an operational voltage of 22.5 V DC with an available drive current capped at 10.8 mA. This allows seamless integration of remote LED indicator lamps mounted above doors, in suspended ceiling voids, or on duct housings to identify alarmed points without degrading loop signaling integrity.

Loop Addressing and System Standards

Loop addressing is configured manually prior to installation using two integrated rotary decade switches, supporting decadic address assignments (01 to 99) for quick panel commissioning and physical device mapping. The unit complies with European standards EN 54-7:2000 + A1:2002 + A2:2006 for point smoke detectors and integrates short-circuit isolation matching EN 54-17:2005. Furthermore, the detector carries Construction Products Regulation (CPR) certification under reference 0832-CPR-F2057 (and CPD 0786-CPD-20739), LPCB approval, and full compliance with RoHS environmental requirements.

Honeywell Morley-IAS HM-PSE-S2 Mounting, Addressing, and Wiring Guide

The Honeywell Morley-IAS HM-PSE-S2 analog addressable photoelectric smoke detector is designed for field deployment across commercial, industrial, healthcare, institutional, and IT data center environments. Correct physical mounting, proper terminal wiring, and accurate manual addressing are vital to ensure full compliance with EN 54-7 and EN 54-17 system engineering requirements on compatible Morley-IAS fire alarm control panels (including the DXc, ZX, and PL series).

Base Compatibility and Mechanical Mounting

The HM-PSE-S2 sensor head integrates directly into the standardized Honeywell Morley-IAS B501AP plug-in mounting base. When seated fully within the B501AP base, the installed assembly measures 102 mm in diameter, 52 mm in total height, and has an assembled weight of 97 g. The detector housing is molded from an ivory-colored PC/ABS polymer blend.

During installation, the B501AP base should be securely fastened to a standard electrical backbox or directly to the ceiling surface prior to inserting the detector head. Once the base is wired and field continuity is verified, align the HM-PSE-S2 sensor body with the base and rotate clockwise until the head engages firmly into the electrical contacts. The unit incorporates dual integrated LEDs providing 360-degree status visibility from floor level.

Loop Wiring and Terminal Specifications

Field wiring must conform to the project schematics and panel design calculations. Terminals located on the B501AP base support solid or stranded conductors up to a maximum wire gauge of 2.5 mm².

Operating Voltage: 15 V DC to 32 V DC operating range supplied directly from the addressable signaling line circuit (SLC).
Standby Current Draw: 200 µA at 24 V DC under non-communicating conditions, and 300 µA at 24 V DC when periodic LED blink is enabled (pulsing once every 5 seconds).
Alarm Current: 3.5 mA at 24 V DC during active LED red alarm status.
Remote Annunciation: Auxiliary terminals provide a remote output rated at 22.5 V DC (at 24 V DC supply) with a maximum current delivery of 10.8 mA to drive optional external indicators.
Loop Impedance Factor: Inserting the detector into the B501AP base introduces a typical additional loop resistance of 20 mΩ (maximum 30 mΩ), which must be incorporated into long-run loop resistance calculations.

Address Setting via Rotary Decade Switches

The HM-PSE-S2 utilizes two onboard mechanical rotary decade switches located on the back of the detector head to set the unique loop address (01 to 99). Use a small flat-blade screwdriver to rotate the switches to the designated address selected on the fire system layout drawing. Both switches must be positively aligned with their numeric indicators before the detector is docked into the B501AP base. Care must be taken during commissioning to verify that duplicate loop addresses are not assigned, as address conflicts will trigger system reporting faults on the loop driver.

Environmental and Pre-Commissioning Checks

The detector operates reliably across an ambient temperature envelope from -30°C to +70°C and a relative humidity range of 10% to 93% (non-condensing). To safeguard the optical sensing chamber and avoid contamination faults, leave any protective dust covers intact until all nearby interior construction, painting, and sanding operations are completely finished. System commissioning can proceed once the addressable loop is energized at nominal 24 V DC and polling communication is acknowledged at the central Morley-IAS panel.

Maintenance, Optical Chamber Cleaning, and Inspection Guidelines

Routine maintenance of the Honeywell Morley-IAS HM-PSE-S2 addressable photoelectric smoke detector is essential for preventing false alarms, addressing chamber contamination, and sustaining compliance with EN 54-7:2000 + A1:2002 + A2:2006 and EN 54-17:2005 standards. Industrial and commercial environments expose sensing heads to airborne particulates, requiring planned servicing procedures.

Chamber Contamination and Built-in Drift Compensation

The HM-PSE-S2 integrates internal smoothing algorithms and automated drift compensation to adapt to gradual airborne dust accumulation without shifting alarm sensitivity thresholds. However, when contamination limits are approached, the intelligent fire alarm control panel (such as Morley-IAS DXc, ZX, or PL series) flags a maintenance alert indicating excessive chamber drift.

Failure to service contaminated units results in false alarms or loop trouble signals. When panel-level drift warnings are triggered, field engineers must dismount the detector from its B501AP plug-in base for servicing rather than resetting the panel threshold repeatedly.

Optical Sensing Chamber Servicing and Filter Cleaning

The external housing of the HM-PSE-S2 is manufactured from durable ivory PC/ABS (polycarbonate/acrylonitrile butadiene styrene). The optical chamber design permits field maintenance through accessible disassembly to protect detection integrity:

Detector Removal: Gently rotate the 97 g detector head counterclockwise out of the B501AP base. Ensure the loop controller is isolated or set to maintenance mode to prevent trouble reporting during device disengagement.
Filter Cleaning: The sensing assembly features cleanable and washable chamber filter elements designed to catch coarse dust, lint, and insects. Carefully extract the filter and rinse using clean, residue-free water or apply clean, low-pressure compressed air (dry gas).
Drying and Reassembly: Ensure washable filter components are 100% dry before reinstalling into the optical assembly. Never use chemical solvents, abrasives, or hydrocarbon-based sprays on the PC/ABS body or the interior optical sensing components.
Inspection of Rotary Decade Switches: Before reinsertion, verify that the two mechanical rotary switches remain set to the correct loop address (01 to 99). Incorrect or accidental adjustments will produce duplicate address faults or missing device warnings on the Morley-IAS loop.

Functional Testing and Operational Verification

After reinstalling the detector into the B501AP base, perform mechanical and functional testing to verify electrical continuity across the loop:

Visual Indication: Check the dual integrated LEDs providing 360-degree status indication. When polling is normal, the LEDs pulse once every 5 seconds (drawing approximately 300 µA at 24 V DC standby).
Aerosol Smoke Testing: Apply an approved, non-residue canned aerosol smoke tester to evaluate the optical scatter response. Upon trigger, the dual LEDs latch into a continuous red illumination, drawing a nominal alarm current of 3.5 mA at 24 V DC.
Remote Output Verification: If an external remote indicator is wired to the base terminals, verify that the remote output provides 22.5 V DC at up to 10.8 mA during active alarm state.
Loop Reset: Clear the fire alarm control panel to return the device to quiescent monitoring (drawing 200 µA at 24 V DC without communication bursts).
