The Honeywell HM-PSE-S2 intelligent addressable photoelectric smoke detector is engineered for direct integration into commercial, institutional, and industrial addressable fire alarm systems. As part of the Honeywell HM Series and S200A detector platform, the device communicates seamlessly over Honeywell addressable loops using Honeywell's advanced digital protocol and analog addressable communication. The unit is designed to be mechanically and electrically backwards compatible with existing Honeywell addressable loop installations, enabling straightforward system expansions and modernization of legacy sites without replacing surrounding loop infrastructure.
Control Panel and Protocol Integration
The HM-PSE-S2 operates on Honeywell intelligent addressable fire alarm control panels that support Honeywell's proprietary advanced digital and analog addressable loop protocols. Point addressing on the signaling line circuit (SLC) is handled directly at the detector head via two integrated rotary decade address switches. These switches permit manual address selection across the full range of 01 to 99, providing clear visual address confirmation during commissioning, routine maintenance, and replacement workflows without requiring handheld electronic programming tools.
Base Compatibility and Mechanical Mounting
The HM-PSE-S2 utilizes a plug-in physical profile designed exclusively for the universal Honeywell B501AP detector base. This shared base standardizes mounting layouts across the entire HM Series detector family. When installed in the B501AP base, the complete assembly presents an outer diameter of 102 mm, an overall installed height of 52 mm, and an aggregate weight of 97 g (including base). The base terminal blocks support field wiring connections up to a maximum wire cross-section of 2.5 mm², accommodating standard industrial fire-rated cables.
Electrical Loop Loading and Output Compatibility
The HM-PSE-S2 is a non-isolated addressable device powered directly from the panel's 24 Vdc signaling loop. Calculating loop loading for battery standby calculations and power supply sizing requires factoring the specific electrical profiles established across its operational modes:
- Standby Current (No Communication): Consumes a maximum of 260 µA at 24 Vdc when communication is idle.
- Standby Current (With LED Polling): Consumes a maximum of 310 µA at 24 Vdc with LED blink enabled at a 5-second polling interval.
- Alarm Current: Pulls 3.5 mA at 24 Vdc to power the dual 360° red status indicator LEDs during an alarm event.
- Remote Annunciator Output: Built-in remote output terminals supply 22.5 Vdc at 24 Vdc loop input, with a rated drive capacity of up to 10.8 mA at 24 Vdc to power external remote LED indicators.
- Loop Series Resistance: The additional loop resistance introduced when mounted into the B501AP base is typically 20 mΩ (maximum 30 mΩ).
