Fire-Lite I300(A)

I300(A) Isolator Module Fire I300(A) Fault Isolator Module is used with addressable fire alarm control panels (FACPs) to the system against wire-to-wire short circuits on the loop. The I300(A) should be placed between each device the SLC loop to isolate a short-circuit problem between the It is required for true Style 7 operation so that other can continue to operate normally in the event of a on the SLC. Powered by SLC loop directly, no external power required. Mounts in standard junction boxes (4.0″/10.16 cm square, cm deep). LED blinks to indicate normal condition. Illuminates when short circuit condition is detected. High noise (EMF/RFI) immunity. Fault Isolator Modules should be spaced between groups sensors in a loop to protect the rest of the loop. Use to iso- short circuit problems within a section of a loop so that sections can continue to operate normally. The I300(A) a maximum of 25 devices in-between isolators, when using relay bases. LOADS PER RELAY BASE AND ISOLATORS/ISOLATOR The maximum number of addressable devices between (or B224BIA isolator bases) is 25 devices. DEVICES base base relay bases draw more current than other intelligent When calculating the 25-device maximum, B224RB rep- 2.5 DEVICES; see example on page 2. ON MAXIMUM NUMBER OF DEVICES: See the SLC (51309) for information on loss of addresses due to current Each module or base added reduces the capacity of positions in an SLC. All SLC field devices must have been after February 1995 to meet the aforementioned If the SLC field devices were purchased prior to 1995, each isolator used reduces the capacity of an SLC two address positions. Requirements differ as applied to relay see note above. Operating voltage: 15 32 VDC (peak). Maximum current upon activation due to short circuit: to the manual for the main FACP. Standby current: 450 maximum; I300(A) is not isolating relay closed. Temperature range: 32 to 120 (0 to 49 Relative humidity: 10% to 93%. Weight: 5 oz. (150 grams). E-940 Devices Dimensions: 4.5 x 4.5 x 0.25 D (11.43 cm H x cm W x 0.635 cm D). face plate is made of off-white plastic. Module includes LED indicator that pulses when normal and illuminates when a short is detected. opens circuit when the line voltage drops below volts. Fault Isolator Modules should be spaced between of addressable devices (maximum 25, see notes on 1) in a loop to protect the rest of the loop. If a short between any two isolators, then both isolators immedi- switch to an open circuit state and isolate the groups of between them. The remaining units on the loop con- to fully operate. Style 4 loops, the I300(A) is generally used at each T-tap to limit the effect of short circuits on a branch to the on that branch. The LED indicator is on continuously a short circuit condition. I300(A) Fault Isolator Module automatically restores the portion of the communications loop to normal. Mount on a standard junction box (4.0″/10.16 cm square) is at least 2.125″/5.398 cm deep. Terminal screws are provided for and out wiring. Surface-mount box is available as an option. instructions are provided with each module. 01/05/2012 Page 1 of 2 Specifications Isolator Modules shall be provided to automatically iso- wire-to-wire short circuits on an SLC loop.
