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.
