Honeywell Morley-IAS HM-PSE-AP System Compatibility and Hardware Interfacing

Control Panel and Protocol Integration

The Honeywell Morley-IAS HM-PSE-AP analog addressable photoelectric smoke detector communicates via Honeywell Advanced Protocol (AP). It is engineered for seamless connection to intelligent fire alarm control panels from the Morley-IAS series, specifically the DXc range, including DXc R7, DXc R8, and DXc R9 control panels. The proprietary Advanced Protocol optimizes loop reporting speeds, stability, and diagnostic signal processing across commercial and industrial network loops.

Device addressing is established through integrated dual rotary decade decimal switches positioned directly on the detector body. These switches permit direct mechanical addressing from address 01 up to 159 under Advanced Protocol. This eliminates the need for external handheld programmers or software assignment routines prior to field installation on compatible Morley-IAS DXc systems.

Mounting Base Compatibility and Form Factor

The HM-PSE-AP is designed to mount onto standard Honeywell System Sensor and Morley B501AP series detector bases. The plug-in twist-lock mechanical interface ensures reliable mechanical retention and continuous electrical continuity across the Signaling Line Circuit (SLC).

• Standard Bases: Fully compatible with B501AP and B501AP-IV addressable detector mounting bases.
• Deep Surface Bases: Compatible with SMK400AP-IV deep mounting base assemblies for installations requiring surface conduit entry.
• Installed Profile: When locked into a compatible B501AP series base, the overall assembly measures 52 mm in height with an outer diameter of 102 mm, maintaining a low-profile aesthetic in open-area ceiling layouts.

Signaling Line Circuit (SLC) and Electrical Compatibility

For system power budget calculations and loop-loading designs, the HM-PSE-AP operates across an input voltage range of 15 to 32 VDC peak. The unit exhibits low current consumption figures that simplify large-scale loop layouts on Morley-IAS DXc loops:

• Standby Current (No Communication): 260 µA at 24 VDC.
• Standby Current (Communication with LED Blink): 310 µA at 24 VDC when the dual status LEDs are configured to blink once every 5 seconds.
• Alarm State Current: Maximum alarm LED current consumption of 3.5 mA at 24 VDC.

Field Wiring and Auxiliary Remote Indicators

Electrical connections are made via the screw terminals of the compatible B501AP base series, which accommodate solid or stranded fire-alarm field wiring conductors up to a maximum wire gauge cross-section of 2.5 mm². This broad cross-section acceptance facilitates robust industrial SLC loop drops and minimized voltage drop over long line distances.

The HM-PSE-AP incorporates dedicated remote annunciator output terminals. The output provides a remote output voltage of 22.5 VDC at a nominal 24 VDC loop supply, supporting an external remote output current of up to 10.8 mA at 24 VDC. This allows system integrators to wire external remote LED indicator lamps for above-ceiling, hidden-void, or locked-room installations without requiring external relays or ancillary modules.
