NOTE: All wiring must conform to applicable local codes, ordinances, and regulations. Mounting Indoor Wall or Ceiling Products 1. Attach mounting base to ceiling or wall. 2. Connect field wiring to terminals: Terminal 1: Relay Output –COM (ZONE+) Terminal 2: Relay Output – NO/NC (ZONE-) Terminal 3: DC Power – Terminal 4: DC Power + 3. To attach product to mounting base. 4. Secure product by tightening the two mounting screws in the front of the product housing. 5. The detector can be connected with Security alarm panel as Figure3. Relay output signal can be changed from Normal Close (NC) to Normal Open (NO) by Jump JP1 on the PCB board. 6. The detector can be connected with conventional alarm panel as Figure 4. One 4.7K ohm resistor should be connected as End of Line (EOL) resistor at the last detector. 7. After the installation, power on the detector, use lighter or candle to test the detector within 3 meters. SETTING FOR WORKING MODE 1. Alarm Relay Output NO/NC setting: The jump setting JP1 is on the PCB board, the alarm relay output can be set to NO or NC by short the left two pin or right two pins. 2. Alarm detect timer setting: When the detector found the fire, according to environment, the detector can be working in four modes as below DIP SW1 switch setting:
The DIP SW1 switch is one the PCB board. 3. Alarm Output mode setting
When the SW1-3 is set to ON (Lock) that mean the detector would keep alarm status until the power supply is cut off. When the SW1-3 is set to OFF (Unlock) that mean the detector would restore from alarm status to normal status when the fire is disappear 30 seconds late. When the SW1-4 is set to OFF that mean the detector connected with security alarm panel. When the detector alarms, the detector would output relay contacts. See Figure 3 for wiring. When the SW1-4 is set to ON that mean the detector connected with conventional fire alarm panel. The internal 470 ohm resistor on the PCB board would serial connected into loop wire. See Figure 4 for wiring. The SW1-3 should set to OFF( Lock) status. The device is an Ultraviolet-only flame detector designed to detect fires and provide alarm outputs directly from the detector while maintaining false alarm immunity. It detects in the ultraviolet (UV) spectral range for optimized speed of response. |
