Presence time: 1 hour for 3% ΔL/L and permanent presence option
Operating Modes: Fail Safe / Fail Secure (selector on faceplate)
Indications: Two face-plate indications are provided:
Red LED – Power
Green LED – channel indicator
1. Tuning – on steady followed by flashing frequency count (x 10 kHz)
2. Undetect – off
3. Detect – on steady
4. Fault – on with short off
Protection: Loop isolation transformer RFI filtering, zener diode clamping on loop inputs and gas discharge tube protection
