4B Detector Base

AJBPIKE — Sun, 07 Oct 2018 13:28:57 +0000

The 4B Universal Base contains no electronics and is suitable for indoor applications of the 614 series conventional (non-addressable), 814 and 850 series analogue addressable detectors. It provides excellent space for cable access and terminations. It features remote LED connections and an antitamper facility. The 4B base is designed to snap-fit into the ceiling tile adaptor, or screw fix to the ceiling in the traditional manner. The Euro Mount Adaptor is a shallow (20mm deep) back box for surface mounting applications. The 4B-6A Adaptor covers ceiling marks revealed when changing from an existing 5” or 6” base.

Specifications

4B-C Continuity Base

AJBPIKE — Sun, 07 Oct 2018 13:28:57 +0000

The 4B-C Continuity Base is used for most installations involving 850 Series detectors, as it allows the detector’s in-built short circuit isolation function to be in-circuit when the detector is fitted and ensures continuity is maintained when the detector is removed.

Specifications
– Ambient Temperature -25°C to +70°C
– Relative Humidity 10% to 95% (n/cond)
– Dimensions (mm) 109 dia x 25H
– Weight 64g
– Indoor Applications Only
– ActivFire Listed with MX detectors

* Maximum number of devices between 5BI bases is limited to 40 for AS 1670.1-2004 systems.

4B-I Isolator Base

AJBPIKE — Sun, 07 Oct 2018 13:28:57 +0000

The 4B-I Isolator Base serves as both a base for an 814 Series MX detector and a protection device against loop short circuits, monitoring the voltage on the MX addressable loop. When a short circuit is detected, the 4B-I isolates the affected section whilst allowing the rest of the addressable loop to function normally. If a detector fitted to the 4B-I exhibits a short circuit, the 4B-I will isolate both sides of the loop from the faulty device without affecting any other device on the loop. An amber LED indicator on the rim of the base illuminates whenever the short circuit isolator is activated. The 4B-I can accommodate one of the MX detectors, or serve as a base for an 814RB.

Specifications
– Operating Voltage 20 to 40Vdc
– Quiescent Current 80µA (max.)
– Tripped Current 3.5mA (max.)
– IB Units betwn 4B-I bases 100 (max.)*
