Answer:
The DXc4 includes 4 detection loops and a 24V DC 4A PSU in a 391.5 mm high backbox housing 2 x 17Ah standby batteries (they are not included). In contrast, the DXc1 has 1 loop in a smaller 260 mm backbox with a 2A PSU holding 2 x 7Ah batteries (they are not included), and the DXc2 provides 2 loops. Unlike the DXc1 and DXc2, the DXc4 does not support the Pt13 System IO Card or the Fire Brigade Control panel.
The Morley-IAS DX Connexion series comprises three primary panel models: DXc1 (1-loop), DXc2 (2-loop), and DXc4 (4-loop). While sharing identical menu structures, 6 × 40 blue LCDs, 160 fire zone support, and BS 5839 part 1 network architecture, they differ across loop counts, hardware options, and enclosure capacities:
- Loop Driver & PSU Capacity: The DXc4 provides 4 loops powered by an internal 24V DC 4A PSU. The DXc2 provides 2 loops with a 4A PSU, whereas the DXc1 provides 1 loop powered by a 24V DC 2A PSU.
- Enclosure Size & Standby Power: The DXc4 and DXc2 share the larger 391.5 mm (H) × 390 mm (W) × 147 mm (D) enclosure capable of housing 2 × 12V 17Ah standby batteries (they are not included). The DXc1 uses a compact 260 mm (H) × 390 mm (W) × 147 mm (D) chassis accommodating smaller 2 × 12V 7Ah standby batteries (they are not included).
- Standby Operating Duration: Standalone backup duration (calculated using Apollo devices) provides up to 48 hours for the DXc4, 72 hours for the DXc2, and 24 hours for the DXc1 under their maximum internal standby battery (they are not included) pairings.
- Hardware Limitations: Support for the Pt13-compliant System IO Card and the Fire Brigade Control & Indication panel is restricted to the DXc1 and DXc2 models; neither card is supported on the DXc4.
