The Honeywell Morley-IAS HM-MCP-GLASS (also catalogued under HM-MCP-GLASS-AP and MOFHMMCPGLASS) is an analogue addressable manual call point engineered specifically for integration into Honeywell Morley-IAS intelligent fire detection networks. To assist system integrators, electrical contractors, and commissioning engineers, the compatibility parameters across control panels, electrical loops, addressing schemes, and backbox infrastructure are outlined below.
Fire Alarm Control Panel Compatibility
The HM-MCP-GLASS communicates over proprietary analogue addressable signaling loops directly supported by Honeywell Morley-IAS intelligent fire alarm control panels (FACP). Verified panel families include:
- Morley-IAS ZX Series: ZX1e, ZX2e, and ZX5e intelligent multi-protocol control panels.
- Morley-IAS DXc Series: DXc1, DXc2, and DXc4 compact networkable addressable panels.
- Morley-IAS STX Series: STX addressable fire alarm control systems.
When connected to a compatible Morley-IAS panel, the device supports bidirectional protocol signaling. The integrated front-facing LED provides real-time status reporting driven directly by the panel's polling routine: blinking red during normal cyclic polling and illuminating steady red upon manual alarm actuation.
Electrical Loop and Power Characteristics
The call point derives operating power directly from the analogue addressable signaling line circuit (SLC), requiring no auxiliary power supplies. Engineers calculating loop loading and battery standby capacity should apply the following operating parameters:
| Parameter | Specification Value |
|---|---|
| Loop Operating Voltage Range | 15 V DC to 32 V DC maximum |
| Quiescent Current (No Communications) | 80 µA at 24 V DC |
| Alarm Current (With Communications) | 130 µA at 24 V DC |
Field wiring integrates via a removable plug-and-play terminal block. This architecture enables loop pre-wiring, conductor isolation, and full loop continuity testing before the sensitive electronic call point module is plugged into place.
Addressing Architecture
Address setting is completed prior to physical installation using integrated rotary decade switches situated on the rear assembly of the device. This hardware-based addressing protocol eliminates the requirement for external handheld programmers and ensures direct parameter assignment within the Morley-IAS loop configuration.
Mechanical Back Box and Mounting Hardware
The call point housing, molded from flame-red (RAL 3001) PC/ABS thermoplastic, supports two distinct physical mounting arrangements:
- Semi-Flush Mounting: Compatible with standard single-gang electrical flush back boxes. In this configuration, dimensions are 89 mm (W) x 93 mm (H) x 27.5 mm (D), with an assembled weight of 110 g to 130 g.
- Surface Mounting: Mounts to a matching red surface-mount back box. In this configuration, dimensions are 89 mm (W) x 93 mm (H) x 59.5 mm (D), with an assembled weight of 180 g.
Environmental and Regulatory System Alignment
The unit conforms fully to European standard EN 54-11 for type A manual call points in fire detection and fire alarm systems. With an enclosure ingress protection index of IP24D, an operational temperature range of -10°C to 55°C, and relative humidity tolerance from 10% to 93% (non-condensing), the HM-MCP-GLASS is engineered for indoor escape routes, corridors, and industrial access portals.
