Emergency Key Switch
The Fase/700 Emergency Key Switch incorporates 2 individual key switches and when connected to a building's fire alarm system, can be used as a simple and effective way to raise bomb alert and lock down alarms. The Emergency Key Switch can be used as a stand-alone unit and will connect to most addressable fire alarm systems via programmable loop input interface units or connected directly to the Fase/702 Class Change & Alert Controller unit.
On-board RGB led’s give continuous indication of the status of each key switch and a 3rd on-board relay can be programmed to energise when a key switch is turned on. This can then be used to signal to the buildings access control system and configured to release certain/all doors or to keep them securely shut dependent on which key switch has been turned.
The Fase Controls Emergency Key Switch Is Available In 2 Versions.
A 12vdc Version and a 24vdc Version. Please Ensure You Order The Correct Unit For Your Needs By Selecting The Correct Supply Voltage In The Above Drop Down List.
Combined Bomb Alert & Lockdown Key Switch
The Easy Way To Raise Bomb Alert & Lock Down Alarms In Your Building
Designed, developed & manufactured in-house by Fase Controls, the Fase/700 Emergency Key Switch is the easy and cost-effective way to raise Bomb Alert and Lock Down Alarms in a building to inform staff and other building occupants of any emergency situations or the need to initiate safety procedures.
The Fase Controls Emergency Key Switch can be installed onto a standard UK size single gang backbox/pattress or dry lining back box and can be used as a stand-alone unit or connected directly to the Fase/702 Class Change & Alert Controller. The 12v version of the Emergency key Switch should be bought if this is being connected to the Fase/702 Controller.
Intelligent Control Of Bomb Alert & Lock Down Alarms
The onboard microprocessor monitors several parameters and gives continuous indication of the health and status of the Emergency Key Switch.
Front-mounted RGB led's give an independent indication of each key switch's current operation, showing as a dim green colour when in standby, waiting for a key switch to be turned. Turn a key switch and the corresponding led turns bright green during a confirmation period of approx. 1/2 second and then red once the confirmation period has passed. Once the led is lit red, the corresponding output relay has energised.
The supply to the Emergency Key Switch is also monitored and indication is given as blue led's if the voltage falls outside the recommended operating voltages. This helps to ensure the unit will be fully operational when an emergency situation arises.
For Connection To An Addressable Fire Alarm Panel
The Fase Controls Emergency Key Switch contains two front-mounted key switches and two output relays. Turning a key switch will energise the corresponding output relay. The output relays are then connected to an addressable fire alarm and the fire alarm system programmed to produce unique tones on receipt of these signals.
Front-mounted RGB led's mounted directly above each key switch give continuous indication of the status of the associated output relay.
To use all of the Emergency Key Switches features, the fire alarm system which this be being connected to must be able to generate the necessary tones.
12vdc & 24vdc Versions
If the Emergency Key Switch is to be powered directly from a fire alarm panel then use the 24v version.
If you are supplying a separate power supply for this then ensure you buy the correct Emergency Key Switch for your selected power supply.
To save confusion or technical complications, only one output relay should be energised at a time. For example, if the LockDown relay has been activated then switching the Bomb Alert relay at the same time may cause confusion.
As default, once one output relay has been energised then the other relay will not energise. Instead, the corresponding led will dim when the second key switch is turned.
However, we have included an 'Allow' configuration dipswitch within the Emergency Key Switch which when switched on will allow both output relays to be energised at the same time. View this page on a desktop monitor and try our simulator towards the bottom of this page to help understand how the Emergency Key Switch operates.
Signal To 3rd Party Equipment
A 3rd configurable ancillary relay has been built into the Emergency Key Switch to allow signals to be sent to access control systems or other 3rd party equipment.
By using the built-in configuration dip switches, this ancillary relay can be programmed to energise when either key switch is turned thus relaying the signal to an access control system to release doors or to keep them securely shut depending on which key switch has been turned.
