ASL ANS Ambient Noise Sensor - Ip65 - Dual Range - Extende
AS-ANS-ANS04-ES
The ANS04-ES is an IP65 rated sample and hold Ambient Noise Sensor which is designed to operate under extreme temperatures, from -40°C to +50°C. The ANS04-ES will work with the whole range of ASL Public Address and Voice Alarm systems and with ASL’s VIPA IP-based PA systems. The purpose of an Ambient Noise Sensor (ANS) system is to adjust the level of public address announcements based on a measure of the ambient noise in the PA zone. This will maintain a set volume of public address audio above the ambient noise, in order to guarantee that the announcement is intelligible, yet at a comfortable level. Each ASL Public Address or Voice Alarm system is able to support the connection of multiple ANS04-ES units. The ANS sensor detects ambient noise using its built-in microphone. The detected signal is weighted with a speech-band response for the best system performance, and is then translated to a value of measured ambient noise in dBA. This value is used to proportionally adjust the Public Address or Voice Alarm system output gain for the configured output channel or channels. The system is set up for the maximum broadcast volume without the ANS sensor, and the ANS system then reduces the gain from this level when the zone is quiet.

AS-ANS-DANS01
• PA announcements dynamically and constantly adjusted to suit the current ambient noise• Reduction of PA noise abatement problems• Retrofittable to VAR12 and VAR20 Routers with software upgradeASL Dynamic ANS System constantly maintains the volume of Public Address announcements just above the ambient noise, guaranteeing that announcements are always intelligible, and not excessively loud. The DANS System employs digital signal processing technology to distinguish the ambient noise from the announcement. This enables adjustments of the broadcast volume level to reflect any variations in ambient noise, even while the announcements are being made. Consequently the overall intelligibility and comfort of announcements are improved over traditional ANS systems, and Public Address noise abatement problems are also improved.
ASL EAP Emergency Announcement Point
ASL EAP Emergency Announcement Point
AS-EAP-EAP01
The EAP01 Emergency Announcement Point is housed in an IP65 vandal resistant, lockable wall-mounting box. It is designed to work with the whole range of ASL Voice Alarm and Public Address systems, and is normally used for making All-Call emergency announcements to entire facilities. The unit features indicators for ‘Busy’, ‘Speak Now’, and ‘System Fault’, together with a ‘Status’ indicator.The EAP01 will operate in an All-Call mode even in the event of processor failure within the Router1, as required by BS5839 Pt.8. The unit should be connected to Router’s inputs 1 or 2, which operate in the All-Call failsafe override mode in the event of processor failure.Hardwired connections to the Emergency Announcement Point interface all LEDs and switches to theRouter, while microphone audio is provided as a balanced 0 dBu (nominal) analogue signal. The EAP01 features a built-in signal limiter to accommodate varying operator technique. The microphone’s processor is responsible for generating an outgoing 20 Hz surveillance tone which is used to monitor the audio connection to the Router, while microphone capsule monitoring is performed by injection and monitoring of a signal such that either open or short circuit of the capsule or associated wiring will indicate a fault.Hardwired connections are provided for the PTT switch, and Speak Now and System Fault LEDs. The cabling to the PTT switch and Speak Now LEDs is continuously monitored by the Router for open and short circuits. Field connections are provided on the inside rear panel of the back box by DIN rail mounted terminals

AS-EAP-SAP02
The SAP02 Station Announcement Point is housed in an IP65 vandal resistant, lockable wall-mounting box. It is designed to work with the whole range of ASL Voice Alarm and Public Address systems, and is normally used for making announcements to station platforms. The unit features indicators for ‘Busy’ and ‘Speak Now’.The SAP02 supersedes the earlier SAP01 Station Announcement Point and its mechanical design provides improved protection against water ingress, is more robust internally, and provides easier installation and operation. Additionally the back box has a splash protected drain hole to provide drainage of unprevented ingress of liquid.A processor within the Station Announcement Point interfaces all LEDs and switches to the Router by means of a serial interface, while microphone audio is provided as a balanced 0 dBu (nominal) analogue signal. The unit features a built-in signal limiter to accommodate varying operator technique. The microphone’s processor is also responsible for generating an outgoing low-frequency surveillance tone which is used to monitor the audio connection to the Router, while microphone capsule monitoring is performed by injection and monitoring of a signal such that either open or short circuit of the capsule or associated wiring will indicate a fault.

The microphones will operate in an All-Call hardware bypass fallback mode even in the event of processor failure within the host Voice Alarm Router1. This hardware bypass function also operates across whole facilities when the microphones are used in conjunction with ASL’s Intellevac safety audio network. There is also a non-EN54 RJ45 Ethernet IP interface with Power over Ethernet capability2 for VoIP connections to ASL IP based PA/VA systems. All interconnect cabling and the microphone capsule is continuously monitored for open and short circuits.

ASL MPS Desk Paging & Emergency Mic - 1 Button - Fist Mic
AS-MPS-MPS01-F0-AN
The MPS range of paging microphones provide live, store-and-forward, and recorded message broadcast into user selected zones. If required, they can also be configured to provide EN54-compliant emergency functions and all EN54 mandatory indicators and controls.The base MPS01 unit consists of a sloping desk console with a flexible gooseneck paging microphone, graphic LCD display, and silent operation ‘Touch to Talk’ touch pad PTT button.Up to five MPX10 button modules can be added to extend the microphone to up to 50 buttons.EN54 CertificationAs part of ASL’s EN54 certified Voice Alarm solution, the MPS can be used as a day-to-day Public Address microphone or as a fully featured emergency microphone at the turn of a key.Multiple InterfacesAlthough the MPS supports our standard analogue & RS485 interface, the MPS can also be used over IP. Simply power the unit using a local PoE supply and connect to the same data network as the VIPEDIA-12 to enable IP connection.Local Music InputA local 3.5mm socket on the MPS makes it simple to connect a local music source, such as mobile phone or iPod, into the public address system. Control zone volumes and turn the music on and off – all from the MPS unit.Store-and-ForwardA simple configuration option allows the MPS to be used in ‘store & forward’ mode where the user’s speech is recorded and played back on release of the microphone’s talk button. This prevents feedback in areas where the MPS needs to be used in close proximity to loudspeakers,Dual Analogue OutputsFor systems requiring high levels of redundancy, the MPS has twin analogue outputs driven from separate internal amplifiers; allowing it to be connected directly to two separate routers in an A/B configuration.Zone Listen-InOperators can listen in to announcements being made to any zone on the system, simply by selecting that zone to listen-in from the loudspeaker inside the MPS base. This is particularly useful where certain zones receive many announcements from different sources, such as on train platforms, and allows the user to be constantly aware of announcements being made around the site.
