TWO-WIRE SMOKE DETECTORS
Omni LTe supports two-wire smoke detectors connected to Zones 1-4.
1. Use normally open (closed for alarm) two-wire "SYSTEM" type smoke detectors (See - 2-Wire Smoke Detector
Compatibility Chart).
2. Smoke detectors must be connected to Zones 1-4 and configured as a Supervised Fire Zone.
3. An external 1000-ohm end-of-line resistor must be used.
4. Connect to the SWITCH 12V or an Output configured as a SWITCHED POWER OUTPUT.
5. The corresponding Zone Jumpers (JP11-JP14) must be in the SMK (smoke) position.
4. Refer to FIGURE 3 (TWO-WIRE FIRE ZONE CONNECTIONS) for this configuration.

FOUR-WIRE SMOKE DETECTORS
Omni LTe supports four-wire smoke detectors connected to any zone (1-16).
1. Use normally open (closed for alarm) four-wire "SYSTEM" type smoke detectors (System Sensor 2112/24TR or
equivalent), rated 8 - 14VDC.
2. An End of Line Power Supervision Relay Module (System Sensor A77-716B or equivalent) is required for UL
installations. Install 1000-ohm end-of-line resistor as shown.
3. Power the smoke detector from SWITCH 12V or an Output configured as a SWITCHED POWER OUTPUT.
4. When connected to Zones 1-4, the appropriate Zone Jumper (JP11-JP14) must be in the SMK (smoke) position.
NOTE: Smoke detectors connected to Zones 1-4 are wired differently from those connected to Zones 5-48.
Refer to FIGURE 4 (FOUR-WIRE FIRE ZONE CONNECTIONS) for each configuration.
