- Up to 12,500 feet (3,810 m) on a Class B (Style 4) SLC loop (twisted-unshielded).
- Built-in degraded mode increases survivability.
- Very simple installation — plug-in style.
- Permits multiple loops in small enclosure
| Item Code: | LCM-320-ST |
|---|---|
| Voltage: | 24 VDC nominal, 27.6 VDC maximum. |
| Maximum loop length: | The maximum wiring distance of an SLC using 12 AWG (3.1 mm²) twisted-pair wire is 12,500 feet (3810 m) per channel. For a twisted-unshielded pair, 12 AWG (3.1 mm²) to 18 AWG (0.78 mm²): – Distance with 12 AWG: 12,500 ft (3,810 m). – Distance with 14 AWG: 8,000 ft (2,438 m). – Distance with 16 AWG: 4,875 ft (1,486 m). – Distance with 18 AWG: 3,225 ft (983 m). – 50 ohms maximum per length of Style 6 & 7 loops. – 50 ohms maximum per branch for Style 4 loop. |
| Maximum current: | 130 mA |
| Maximum resistance: | 50 ohms (supervised and powerlimited). |
| Temperature and humidity ranges: | This system meets NFPA requirements for operation at 0 – 49°C/32 – 120°F and at a relative humidity 93% ± 2% RH (noncondensing) at 32°C ± 2°C (90°F ± 3°F). However, the useful life of the system’s standby batteries and the electronic components may be adversely affected by extreme temperature ranges and humidity. Therefore, it is recommended that this system and its peripherals be installed in an environment with a normal room temperature of 15 – 27°C/60 – 80°F. |
