LC1 Modular Ceiling Loudspeaker Range
Functions Voice Alarm applications Voice alarm loudspeakers are specifically designed for use in buildings where system performance for verbal evacuation announcements is governed by regulations. The LC1 Modular Ceiling Loudspeaker range is designed for use in voice alarm systems and is compliant with British standard BS 5839‑8. Protection
4
The loudspeakers have built-in protection to ensure that fire damage to the loudspeakers does not cause failure of the connected circuit. In this way system integrity is maintained, ensuring loudspeakers in other areas can still be used to inform people of the situation. The loudspeakers can also be used in combination with a metal fire-dome to increase protection of the cable termination. Connections
Features
The loudspeakers have a ceramic screw-terminal connection block, thermal fuse and heat-resistant, hightemperature wiring.
▶ Excellent speech and music reproduction ▶ Easy installation with one grille size and one complete set of accessories ▶ Suitable for 70 V and 100 V ▶ Choice of different ceiling mounting methods ▶ Optional Pilot Tone indication ▶ Provision for mounting of the optional line / loudspeaker supervision board ▶ Installation friendly fire-dome with innovative ceramic connector (patent pending) ▶ EN 54‑24 certified ▶ UL listed, BS 5839‑8 and EN 60849 compliant
The LC1 Modular Ceiling Loudspeaker range can be used for a wide variety of ceiling environments. They provide excellent speech and music in indoor public address applications. The range offers a choice of four loudspeakers distinguished by input power, opening angle and sound reproduction. It includes two 6 W single cone loudspeakers offering a choice of opening angle and two high performance 12 W and 24 W coaxial loudspeaker drivers. They all have the same grille size and can be used in combination with the same mounting accessories. The loudspeakers are suitable for use in air‑handling spaces when installed with the LC1‑MFD enclosure. The loudspeaker frame includes provision for mounting the optional pilot-tone indication board or WLS board and has standard a light conductor to indicate the pilot-tone status.

Installation/Configuration Notes Installation The LC1 Modular Ceiling Loudspeaker range is very installation friendly. The loudspeaker consists of a frame with the loudspeaker driver and metal grille with integrated light conductor, matching transformer and ceramic screw terminal connection block. On the loudspeaker are provisions for mounting the optional pilot-tone indication board and optional line/loudspeaker surveillance board.
LC1-CBB Back Box On top of the mounting ring, provisions are present to “click-on” the optional Back Box. The combination of Mounting Ring and Back Box prevents sound traveling via the ceiling cavity to adjacent areas, and fully protects the loudspeaker from dust, falling objects. The Back Box has knock‑out holes for two grommets (11 mm/0.80 in) and for two cable glands (20.5 mm/ 0.80 in)
4
Power tapping on the 70 V / 100 V matching transformer allows selection of full-power, half-power, quarter-power and eight-power radiation. Ordering information Due to the modular concept of this system, it is important to order not only the ceiling loudspeaker LC1‑xMxxE, but also the flush ceiling mounting accessory of your choice, as mentioned here below. The loudspeakers can be flush mounted into the ceiling by means of the “U” shaped Metal Mounting support bracket LC1‑MMSB or the ABS Ceiling Mounting ring LC1‑CMR with optional Back Box LC1‑CBB. In order to take full advantage of the modular architecture, all parts are separately packaged in the order in which they are required for installation. LC1-MMSB Mounting Support Bracket The metal Mounting Support Bracket has two ceiling clamps, which are secured with thumb screws in the ceiling hole. The bracket is also provided with two 4 mm holes for mounting the bracket with two screws into thin (metal) ceilings. Two spring catchers (for accepting the Vshaped loudspeaker springs) are provided. The bracket provides a provision for attaching an optional safety steel cord.
LC1-CMR and LC1-CBB Ceiling Mounting Ring and Back Box assembly LC1-CSMB Surface Mounting Box This ABS Surface Mounting Box is available for securing the ceiling loudspeaker to walls or hard ceilings. The Surface Mounting Box has at the side two holes standard covered opposite positioned and four knock‑out holes on the rear side. For optional single point suspension of the assembly of Ceiling Loudspeaker and Surface Mounting Box, a separate metal suspension kit, LC1‑MSK is available.
LC1-MMSB Metal Mounting Support Bracket LC1-CMR Mounting Ring The LC1‑CMR is an alternative for the ceiling mounting support bracket. The ABS Mounting Ring has two screw driving clamps to fix the mounting ring into the ceiling board. Inside the ring, two spring catchers (for accepting the V-shaped loudspeaker springs) are provided.

LC1-MFD Metal Fire Dome with innovative ceramic connector (patent pending) LC1-PIB Pilot‑tone Indication Board The loudspeakers have provision for optional mounting of the Pilot‑tone Indication Board. This small PCB with LED can fixed into a holder, connected to a light conductor standard fitted. The presence of the pilot‑tone and functioning of the loudspeaker can be visually checked by means of the flashing of the LED, integrated in the front grille rim. The required level of the pilot tone signal is 4 V rms @ 20 kHz and the load to the amplifier from these boards is negligible.
LC1‑MSK Metal Suspension Kit LC1-MFD Metal Fire Dome Ease of installation for individual loudspeaker and loudspeaker/fire-dome combinations. The Fire Dome mounting is fixed in the ceiling, prior to the ceiling speaker mounting. The Fire Dome has a dual connection entry, enabling loop‑through cabling and provision for attaching an optional safety steel cord. Connections are made using an innovative ceramic screw terminal connection block on the metal fire dome with loop-through facility. Suitable for use in air‑handling spaces.
