- Serial mode programmable
- Left Zone - EOLR supervised, open or closed circuit sensors
- Right Zone - unsupervised, closed circuit sensors
- UL listed for fire and burglary installations
- The 4190SN consists of two detection loops, known as the left (primary) and right (secondary) loops. The left loop can be used for:
- Closed-circuit devices with or without EOLR supervision
- Open-circuit devices, with EOLR supervision
- Fast-response (10 millisecond) devices
- The right loop can be used for:
- Closed-circuit devices only
- Has no EOLR supervision
- 400 millisecond response time
- The jumpers do not affect the operation of the right loop. The right loop cannot be used alone.
The tamper/supervision response of the 4190SN is determined by the zone response type assigned to the left loop zone. While the system is armed, tamper/supervisory faults will report as alarms if the left loop zone is assigned a burglary response type and will report as troubles if the left loop zone is assigned a non-burglary response type (i.e., fire, panic, aux). While the system is disarmed, tamper/supervisory will always report as troubles.
