Fire Detectors And Sounders Easily Fitted To False Ceilings With New Mounting Box

Apollo’s new ceiling tile mounting box allows bases for fire and smoke detectors and sounders to be fitted, wired, tested and commissioned quickly and easily prior to the addition of a false ceiling. When the false ceiling is in position the mounting box is simply slotted into place without disturbing the wiring. A separate back box is not required, as it forms part of the mounting box, and detector heads can be fitted to the bases prior to installation.

The device can be used with ceiling tiles up to 25mm thick. Moulded springs on the back of the mounting box automatically adjust to the tile’s thickness, while plastic blades embedded in the back of the tile secure it into position.

The mounting box includes three M20 and two M25 knock-outs and a guide showing the size of hole that should be cut in the ceiling tile. If the hole is cut too big, the device includes slots that allow it to be screwed onto the tile.

The product is available with one of two different-sized retaining rings, one for use with Apollo detector bases 45681-309 and another for sounder bases 45681-310.

Apollo Intelligent Fire Detection System Brings Programmable Protection To The Ulster Hall, Belfast

Apollo Discovery multisensors lie at the heart of an intelligent fire detection system installed to protect Belfast’s Ulster Hall. The fire detection system features different sensitivity levels depending on the time of day and was supplied and commissioned by Ashdale Engineering Ltd, which is also responsible for its maintenance.

A two-storey concert hall and exhibition venue, The Ulster Hall dates back to 1862 and is one of the oldest buildings owned by Belfast City Council. It has capacity to host approximately 2,000 people in the main hall and 200 in the group hall. The building is made up of a great deal of timber work and houses the Mulholland Organ, which was donated to the people of Belfast by its ex-Mayor, Andrew Mulholland, at around the time that the hall was built.

 The design of the fire detection system had to take into account the uses of the building, particularly as a concert hall, and had to also ensure that false alarms caused by concert smoke machines and cigarette smoking were avoided.

Comments Colin Simms, Service Manager of Ashdale Engineering: “Apollo technology is very versatile. Using multisensors from Apollo’s Discovery range allowed us to provide different levels of sensitivity for the building at different times of day. For example, the fire detection system can switch the combined smoke/heat multisensors in the roof space to heat detection only when performers are using smoke machines in the main hall.”

This was possible because Apollo Discovery fire detectors feature five panel-selectable sensitivity bands that make them particularly adaptable to changing conditions. To help to protect against unwanted alarms even further, devices in the Discovery range are also equipped with inbuilt drift compensation, a non-volatile memory and fail-safe operation.

The Ulster Hall fire detection system incorporates over 150 Apollo Discovery multisensors as well as 100 loop-powered beacons. With a low current consumption of just 3mA, Apollo loop-powered beacons can be incorporated on an existing loop, reducing installation time and cost. The loop-powered beacon uses LEDs instead of Xenon for added reliability and is fully addressable, using the same XPERT address system as Apollo’s XP95 and Discovery detectors.

A number of interface units enable an alarm to shut down the boiler control panel, open the smoke extraction vents, bring the lift to the ground floor and operate the aspiration system in the lift shaft. The system is governed by a purpose-designed Advanced Electronics four-loop panel plus four repeater panels networked together. A Signet PAVA system is also connected.

The fire detection system is programmed with two modes of operation: ‘performance mode’ and ‘non-performance mode’. The first is activated when a show is on, with a three-minute interval before evacuation to allow an alarm to be investigated by staff. Non-performance mode is used at night and when the building is not occupied. An alarm in this case will effect an immediate ‘one out, all out’ evacuation of the building.

Summing up, Colin Simms says: “Apollo Fire Detectors offers a reliable open protocol system and the fact that the products are readily available if spares are required is a definite plus. The ease with which the Apollo system can be commissioned and installed was also a great benefit. Apollo was the obvious choice for the fire detection system for The Ulster Hall.”

Apollo Used In New Orleans Recovery Project

Fire detectors manufactured by Apollo Fire Detectors Limited are being installed as part of the recovery process In New Orleans, following Hurricane Katrina.

Hurricane Katrina

The New Orleans project is being undertaken by Apollo’s US partner Computrols Inc, a leading manufacturer of building control equipment. The company has been instrumental in helping businesses devastated by Hurricane Katrina to re-open as quickly as possible, countering the economic impact of the worst natural disaster in America’s history.

Hurricane Katrina first struck US soil on 25th August 2005. It proved to be the most destructive and costly tropical cyclone of all time, cutting a swathe through the Bahamas, South Florida, Mississippi, Alabama, the Florida Panhandle and Louisiana. It was particularly devastating in New Orleans, where the storm waters breached the levee system and flooded the town. The damage caused by Hurricane Katrina is estimated between US$70-130 billion. 1,302 people lost their lives and over one million were displaced.

While international, federal and state aid has been swift in coming, many people who live and work in the affected areas want to return to normal routine as soon as possible. Computrols Inc has been aiding the recovery effort by equipping buildings with Apollo-based fire detection systems to bring them back into use.

To date, Computrols Inc has installed Apollo-based fire detection systems in three buildings in New Orleans as part of their contribution to the region’s recovery. One example is an office building some 50 storeys high. Leased out as commercial office space to a number of different occupants, the building specification required a UL-listed fire detection system installed in accordance with NFPA72. Computrols Inc supplied and installed an intelligent fire system based on Apollo’s open digital protocol. The system comprises five cSimon control panels and over 700 devices, including 30 strobes, 200 motion modules, 350 Apollo Discovery intelligent smoke detectors and 31 duct detectors.

The system is equipped with an audio evacuation unit that enables an alarm to be raised either in a specific zone, or throughout the entire building. This ensures that no unnecessary distress or inconvenience is caused to occupants on floors not affected by a fire alert and helps with phased evacuation in the event of an emergency.
