Emergency lighting units could be connected to the central controller using SRM or DALI bus. For expanding installations without adding the bus wiring, the wireless option could be used. The standard MIRO or SRM Emergency Lighting Device could be converted into the wireless unit by replacing the option module. OP-RADIO supports only SRM system integration, for the DALI systems OP-RADIO2 option needs to be used.
The wireless module form factor and pinout is matching existing OP-SRM and OP-MIRO modules.
OP-RADIO module is available in 3 options:
- OP-RADIOI – Integrated ceramic antenna and 8-pin socket for direct mounting on the Emergency Lighting Unit or one of the Controller units (C-BOX, MWEB, MIRO-WEB)
- OP-RADIOE – Integrated ceramic antenna and 4-pin plug for mounting with 1 ft extension cable
- OP-RADIOX – External antenna U.LF connector and 4-pin plug for mounting with 1 ft extension cable
The module OP-RADIOX could be equipped with one of the following external antennas:- Type 1: Taoglas FXP73.07.0100A 2.5dBi
- Type 2: Digi International A24-QUF-P4S
- Type 3: Taoglas FXP70.07.0053A 5dBi
- Type 1: Taoglas FXP73.07.0100A 2.5dBi
OP-RADIO operating parameters:
- Radio band: ISM 2.4 GHz
- TX power: up to 2 mW (+3 dBm .. -30 dBm)
- Power supply: 2.0 – 3.3 VDC @ 16 mA
- Host communication: UART 300-57k baud
Wireless products are available in 3 OP-RADIO configurations:
- I – module with on-board ceramic antenna, internal installation
- E – module with on-board ceramic antenna, external installation with 1 ft cable
- X – module with external antenna connector (U.FL type), requires specification for the external antanna type as described above
Internal ceramic antenna is not available for LEGR and all units with metal enclosure.
Sample product names configured with wireless option:
- LEJC3-SFI 350/2SC/180
- LEJC3-SFE 600/4LA/180MH
- LEJC3-SFX 300/2D/180
- LEGR-SFE 1-3/2/180
- LEGR-SFX 1-3/2/180
- LEHF-SFE 220V-3W/4SC/60
- LEHF-SFX 50V-6W/4LA/60MH
For example here is an OP-RADIO module installed on the LEJC board:
Module is powered from host system, and communicates through UART connection. Module features two test LEDs, which could be used for real-time wireless connectivity verification. Any two modules could be instructed to execute continous sending of the test data packet at 4 Hz repeat frequency (4 packets per second). First led will be switched off when one packet is missed, and second one will be switched off if 4 packets are missed in the row.
