SIEMENS FDBZ492-RTL Remote Alarm Indicator
INTRODUCTION
The FDBZ492-RTL Remote Alarm Indicator (Figure 1) works with the FDBZ492-R or FDBZ492-PR Air Duct Housing with Relays. The LED on the remote indicator mimics the color of the LED on the detector. Use the re-mote indicator in applications where the detector is not easily viewed, such as air ducts and drop ceilings.
The FDBZ492-RTL also works with FDBZ492-HR to monitor and test its relay
output. Its LED will indicate if the relay is in standby (GRN) or alarm (RED)
state. The FDBZ492-RTL provides a key operated detector test function. When
this key is turned to the Test posi-tion, the relay on the FDBZ492-R,
FDBZ492-PR and FDBZ492-HR Air Duct Housing will activate and the LED will
flash red.
When the key is turned to the Normal position, the relay on the FDBZ492-R,
FDBZ492-PR and FDBZ492-HR Air Duct Housing will deactivate and the LED will
flash green.
Each FDBZ492-R or FDBZ492-PR Air Duct Housing with Relays can drive one FDBZ492-RTL; however, the total number of detectors and remote indicators must not exceed 30 devices on an initiating zone. The FDBZ492-RTL contains an LED indicator that flashes in one of three colors: green, yellow, or red. When the FDBZ492-R or FDBZ492-PR Air Duct Hous-ing with Relays flashes, the remote indicator flashes in the same color. The flashes occur approximately every 7 seconds and are described in Table 1.
| LED Status | Indicates |
|---|---|
| Green | Normal supervisory operation. Smoke sensitivity within rated limits. |
| Yellow | Detector requires service or is operating beyond its environmental |
specifications or outside of the detector sensitivity range.
Red| Alarm condition. LED flashes every 2.5 seconds
No flash| Detector or FDBZ492-RTL is not powered or requires repair.
Applicable to conventional detectors only
INSTALLATION
The remote indicator may be placed up to 25 feet away from its associated detector using 14-18 gauge wire.
- Use a single-gang switch box (user supplied) for mounting the FDBZ492-RTL.
- Wire as shown in Figure 2.
- Electrical Ratings: 0.2mA (max) @ 24VDC
