Answer:
Installed in a B501AP base, the Honeywell HM-RHSE measures 102 mm in diameter and 61 mm in height, with an installed weight of 88 g (0.12 kg shipping weight). It operates on a 15 to 32 V DC loop supply, drawing 200 µA standby current at 24 V DC (300 µA with 5-second LED blink enabled) and 3.5 mA in alarm condition.
The Honeywell HM-RHSE intelligent rate-of-rise thermal detector features the following electrical and physical specifications when deployed on compatible addressable fire loops:
- Installed Dimensions: 102 mm (diameter) × 61 mm (height) when seated in the standard B501AP mounting base.
- Product Weight: 88 g net weight (including base); gross shipping weight is 0.12 kg.
- Operating Voltage Range: 15 V DC to 32 V DC loop power.
- Standby Current Draw: 200 µA at 24 V DC (without communications); 300 µA at 24 V DC (with LED blink enabled once every 5 seconds).
- Alarm Current Draw: 3.5 mA at 24 V DC (LED continuously illuminated).
- Additional Loop Resistance (B501AP): Typically 20 mΩ (maximum 30 mΩ).
- Operating Environment: Operating temperature range is -30°C to +70°C (with a maximum normal continuous ambient application limit of 50°C) and relative humidity of 10% to 93% non-condensing.
- Terminal Capacity: Direct screw terminals on the base accommodate field wiring conductors up to 2.5 mm².
