SECTION 13850

2 .4 System component

1. Analog Photo Sensors

1. Each sensor shall store the sensor address and operating characteristics in non-volatile memory at the sensor. The sensor shall use a threshold received from the control unit to determine when an alarm condition exists.
2. Each sensor shall have two alarm LEDs for 360° viewing. The alarm LEDs shall flash when communicating with the control panel. The alarm LEDs will illuminate steady during alarm conditions.
3. Sensitivity settings for photoelectric sensors shall be set and displayed on the LCD in % obscuration per foot.
4. Each sensor shall be capable of compensating for dust and dirt accumulation within the sensing chamber.
5. A calibrated light source shall be used to calibrate the fire level of the photoelectric sensor. Sensors which use a fixed fire level limit are not acceptable.

2. Analog Ionization Sensors

1. Each sensor shall store the sensor address and operating characteristics in non-volatile memory at the sensor. The sensor shall use a threshold received from the control unit to determine when an alarm condition exists.
2. Each sensor shall have two alarm LEDs for 360° viewing. The alarm LEDs shall flash when communicating with the control panel. The alarm LEDs will illuminate steady during alarm conditions.
3. Each sensor shall be capable of compensating for dust and dirt accumulation within the sensing chamber

3. Analog Thermal Sensors

1. Each sensor shall store the sensor address and operating characteristics in non-volatile memory at the sensor. The sensor shall use a threshold received from the control unit to determine when an alarm condition exists.
2. Each sensor shall have two alarm LEDs for 360° viewing. The alarm LEDs shall flash when communicating with the control panel. The alarm LEDs will illuminate steady during alarm conditions.
3. Sensitivity settings for thermal sensors shall be set and displayed on the LCD in degrees fahernheit. The set point for the thermal sensor shall be adjustable between 100° F and 156° F. The thermal detector shall operate on a fixed temperature principle.

4. Fast Response Contact Module

1. Contact modules shall provide monitoring of dry contacts as initiating devices.
2. Each module shall store the sensor address and operating characteristics in non-volatile memory at the module.
3. The module shall be mounted to a standard junction box and provide visual indication of status via a status LED. Optional mounting shall be available to allowing mounting the module in a junction box with a monitored contact.

5. Supervised Output Module

1. Each supervised output module shall be rated to operate listed notification appliances.
2. Circuit shall be rated for 2.0 amps @ 24 VDC.
3. Each module shall store the sensor address and operating characteristics in non-volatile memory at the module.
4. Each module shall be individually selectable for silencing and walktest. A module programmed to operate during walktest will initiate the programmed pattern for 4 seconds when the appropriate initiating conditions are satisfied.
5. Each module shall operate under up to 16 different conditions occurring in the system. These conditions include combining various zones and zone states.

6. Solenoid Releasing Module

1. Circuit shall be rated for 2.0 amps @ 24 VDC.
2. Each module shall store the sensor address and operating characteristics in non-volatile memory at the module.
3. The module shall be capable of actuating a listed solenoid or an Agent Release Circuit.
4. The module shall be protected from false actuation by a intelligent transistor.

7. Dual Relay Module

1. The module shall provide two independently operating and configurable relays.
2. Each relay shall be rated for 2.0 amps @ 24 VDC.
3. Each module shall store the sensor address and operating characteristics in non-volatile memory at the module.
4. Each module shall operate under up to 16 different conditions occurring in the system. These conditions include combining various zones and zone states.
5. The module shall operate both relays without requiring a separate power source.
