{"product_id":"900m-long-range-wireless-warehouse-bell-kit","title":"900m Long Range Wireless Warehouse Bell Kit with 85dB Bell \u0026 Heavy Duty Push Button","description":"\u003cp\u003eIf drivers are waiting at a shutter door because nobody on the warehouse floor can hear a knock, this kit closes that gap without a cable run across the yard. You fit a heavy duty push button where visitors arrive and a loud red bell where your team works. A press of the button sets off the bell and a chime on a receiver in your office, over a wireless link rated at 900 metres line of sight. It suits goods-in doors, factory gates and farm yards, or any site where the person answering is rarely in one place.\u003c\/p\u003e\n\n\u003ch2\u003eWhy it works\u003c\/h2\u003e\n\n\u003ch3\u003eThe wireless link does the hard part\u003c\/h3\u003e\n\u003cp\u003eTrenching or overhead cabling between buildings is what usually makes a site-wide bell expensive. Here nothing needs laying between the transmitter and the receiver. Be realistic about the figure: 900 metres is line of sight, and the working range on most sites is around 400 to 600 metres because buildings and steelwork weaken the signal.\u003c\/p\u003e\n\n\u003ch3\u003eEach part sits where it does its job\u003c\/h3\u003e\n\u003cp\u003eThe button and transmitter are joined by 3 metres of bell cable, so the button can sit at the door while the IP65 transmitter box goes wherever it transmits best, such as the back of a post or just inside a factory wall. A second 3 metre cable lets the receiver stay in the dry while the bell goes out into the warehouse or yard.\u003c\/p\u003e\n\n\u003ch3\u003eTwo ways to be alerted\u003c\/h3\u003e\n\u003cp\u003eThe receiver has its own chime with adjustable volume and drives the wired bell at the same time, so the office hears the chime and the floor hears the bell. When the site is closed, you switch the receiver off.\u003c\/p\u003e\n\n\u003ch2\u003eWhere it's used\u003c\/h2\u003e\n\u003cp\u003eWarehouses and factories are the obvious fit, particularly for goods-in doors and rear gates out of earshot of the office. It is also used on farms, in schools and workshops, and for detached offices. The same system can work as a staff call point or simple alert, though it is sold as a call and alert bell, not as a fire alarm system.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eKit contents\u003c\/th\u003e\n\u003ctd\u003ePush button with bell symbol, battery transmitter with mounting box, plug-in receiver, 3-pin plug-in transformer, bell, 2 x 3 metre bell cables\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWireless range\u003c\/th\u003e\n\u003ctd\u003e900 metres line of sight, around 400 to 600 metres in most applications\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBell\u003c\/th\u003e\n\u003ctd\u003eApprox 85 decibel, 12V DC, 150mm diameter x 60mm deep, bracket with 4 holes, external use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePush button\u003c\/th\u003e\n\u003ctd\u003e85 x 40 x 40mm, sealed wired contacts, NO or NC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTransmitter\u003c\/th\u003e\n\u003ctd\u003e90 x 40 x 15mm, 1 x MN21 12V battery, 433 MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTransmitter box\u003c\/th\u003e\n\u003ctd\u003ePlastic, IP65, external 195 x 90 x 45mm, internal 133 x 83 x 35mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReceiver\u003c\/th\u003e\n\u003ctd\u003e160 x 105 x 35mm, 15V DC 1 amp transformer, 434.6 MHz, on\/off button, adjustable volume\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReceiver output\u003c\/th\u003e\n\u003ctd\u003e12V DC for 1, 10 or 60 seconds or 5 minutes, relay rated 24V DC or 120V AC at 2 amps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCapacity\u003c\/th\u003e\n\u003ctd\u003e4 channels, 32 sets per channel, 128 sets per receiver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCurrent draw\u003c\/th\u003e\n\u003ctd\u003eStandby 20 mA, alarm 180 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e1 year manufacturer warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBattery life, operating temperature\u003c\/th\u003e\n\u003ctd\u003eNot published for this line\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eChoosing the right option\u003c\/h2\u003e\n\u003cp\u003eThis is a single kit with one button and one bell, so the question is whether it fits your site. Walk the route first. With a clear view between the two ends and under about 400 metres, you should be well inside the working range. If the signal has to pass through several steel buildings, test before you fix anything permanently.\u003c\/p\u003e\n\u003cp\u003eYou need a mains socket near the receiver, and the bell is wired to the receiver rather than wireless. That cable can be extended with ordinary 2-core bell cable, though a maximum length is not published for this line. Extra push buttons, receivers, bells and a signal repeater, which can at least double the range, are not included, so contact us before ordering if you need them.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation, use and care\u003c\/h2\u003e\n\u003cp\u003eMount the push button, then fix the transmitter box with its four screws. Mount the receiver near a socket and plug in the transformer, then fix the bell using the four holes in its bracket. Either cable can be removed to pass through a wall or post. Press the button to test the whole route before you finish off. If the bell stops responding reliably, check the transmitter's MN21 battery first.\u003c\/p\u003e\n\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003ch3\u003eWill it really reach 900 metres?\u003c\/h3\u003e\n\u003cp\u003eOnly with a clear line of sight between transmitter and receiver. On most working sites, expect around 400 to 600 metres, because buildings and steelwork reduce the signal.\u003c\/p\u003e\n\u003ch3\u003eDoes the bell need its own power supply?\u003c\/h3\u003e\n\u003cp\u003eNo. The bell takes 12V DC from the receiver through the 3 metre cable, and the receiver runs from the plug-in transformer. The button side runs on the transmitter's battery.\u003c\/p\u003e\n\u003ch3\u003eCan the parts be fitted outdoors?\u003c\/h3\u003e\n\u003cp\u003eThe bell can be fitted outside, the transmitter box is rated IP65 and the button has sealed contacts. Keep the receiver in an office, gatehouse or similar dry room with a socket nearby.\u003c\/p\u003e\n\n\u003ch2\u003eOrdering and delivery\u003c\/h2\u003e\n\u003cp\u003eThe kit is supplied new as one complete set, with the transformer and transmitter battery included, and is sent to a UK address by tracked courier.
