Fire Alarm Detector Bases in Bhopal

The base must match the detector range, because each maker designs its bases for its own heads. Apollo's XPERT 8 base fits all Soteria, Discovery and XP95 detectors, the XPERT 7 base suits XP95 and Discovery, and the Series 65, Orbis TimeSaver and AlarmSense bases serve those conventional ranges. The Agni FL-433/SB fits FYRLAAST detectors; the Bosch MS 400 suits AVENAR detector 4000 and FCP-320 detectors, while FAP-520 detectors need the FAA-500 LSN base; the Ceasefire TI-002231 fits Intelli-Sense and the TI-002270 fits both Pro-Sense and Intelli-Sense. Siemens DB721 and DB722 fit Cerberus PRO FD720 detectors, FDB221-AA and FDB222 fit Sinteso and DB110D fits Cerberus FIT 110-series detectors. The System Sensor B501AP takes Series 200 sensors, the Morley by Honeywell MI-B501AP takes the Morley Advanced intelligent ranges, and the System Sensor B401 is a plug-in base for 2-wire conventional heads.

Then choose any extra function. An isolator base cuts off only the short circuited section of a loop: the Agni FL-433/IB allows up to 70 devices between isolators, the Apollo XPERT 7 isolating base up to 20 detectors or equivalent load between isolating bases, the System Sensor B524IEFT-1 up to 99 isolators per loop, and the Notifier B224BI-WH is a 6.2 inch intelligent isolator base. A relay base lets the detector switch local equipment when it alarms: the Apollo Series 65 relay base and Bosch FAA-MSR420 have changeover (form C) contacts, the Orbis TimeSaver relay base switches up to 30 V at 1 A, and the Bosch FAA-500-R serves FAP-520 detectors in uses such as emergency door control. Notifier B200S sounder bases share the detector's address, so the panel can sound one base or a group.

Some places need a special base. To keep a circuit working while a detector is out, the Apollo Series 65 diode base serves conventional circuits that share call points and detectors, the Siemens DB110D conventional base includes a continuity diode, and the Siemens DB721 has a loop contact that keeps the detector line closed with no detector fitted. For hazardous areas, the Apollo XPERT 7 I.S. base accepts only intrinsically safe detectors and carries PESO (CCoE) and DNV.GL approvals, and the Bosch FDB201 is the base for the OOH740-A9-Ex detector used in potentially explosive areas. Where frost or condensation could cause false alarms, the System Sensor B524HTR heater base raises the sensor temperature by a few degrees, and for flush ceilings the Apollo Soteria Dimension mounting box sets Soteria Dimension detectors into a ceiling opening.

Finally check the fitting details. Most bases can lock the detector against unauthorised removal, for example the Apollo Series 65 with a grub screw and a 1.5 mm hexagonal screwdriver, the System Sensor B501AP by breaking off a plastic tab, and the Bosch MS 400 and FAA-MSR420 with a lock or clip. Sizes and colours differ: the Ceasefire bases are 110 mm across and 16 mm deep, the Notifier B501-WHITE is a 4 inch flangeless base, and the Morley by Honeywell MI-B501AP and System Sensor B501AP come in white, ivory and black. Notifier bases are UL/ULC listed and FM approved, while Apollo, Bosch and Siemens bases list approvals such as LPCB, VdS, CPR and UKCA, so match what your project specifies.
