Cranford Controls VPR-MT32-230-W White Sounder 110 230v 32 Tone

Cranford Controls VPR-MT32-230-W White Sounder 110 230v 32 ToneEach device is synchronised via its high frequency oscillator circuit and gives sound outputs with frequencies of between 440Hz - 2850Hz dependant on tone selected. Tones are selected via the DIL switch fitted to the PCB. By using three wires a second stage alarm may be switched so that the continuous tone will override the tone selected.The sounder case material is ABS and is supplied as standard in red. A white version is also available. Each sounder is supplied complete with its own mounting base which contains marker points for drilling two M20 gland entries. The installation of the VPR-MT32-230 sounder is not recommended in industrial areas. These units do not require an earth connection as each device has its own transformer and de-coupling between mains frequencies.

Fireclass 3-87-0351FC Door Release Magnet Set Wall Mount ABS Housing 24VDC

Fireclass 3-87-0351FC Door Release Magnet Set Wall Mount ABS Housing 24VDCElectromagnetic fire door holders are designed to hold open fire doors in any areas where easy access is essential in relation to the Equality Act and can be used in conjunction with any suitable fire alarm systems. When an alarm is triggered power to the door holder is cut allowing the fire door fitted with its standard closing mechanism to shut automatically. Doormouse door holders are fitted with an integral manual release button allowing the door to be closed without operating the fire alarm.The Doormouse door holder is surface mounted and is housed in a white fire resistant ABS casing. Type tested to meet EN1155 knockouts for surface or back cable entry and a spring loaded pin to give zero residual holding force when de-energised.The 230Vac unit includes a filter for EMC emissions and is CE marked. Internal diodes dissipate any back EMF on switchoff reducing wear at the control unit.The Doormouse is ideal for use in any public access areas including hospitals offices hotels and nursing homes.Key Features24Vdc or 230Vac supply voltageZero residual force200N 500N holding forceFire resistant ABS casingApproved to EN1155 and CE markedHigh quality cost effective packageIncludes fitting instructions

Apollo AlarmSense Open Area Sounder 55000-018APO

Apollo AlarmSense Open Area Sounder 55000-018APOThe AlarmSense open area sounder has an IP65 rating meaning that it is suitable for outdoor use. In the event of unauthorised sounder head removal the unit generates a fault warning but all other devices on the same zone will continue to operate.Brand InformationAlarmSense is a range of conventional fire detection and alarm products designed to be connected to the same pair of supply wires making installation quicker and less expensive.AlarmSense has been developed to make the design and installation of a fire detection and alarm system easier and more economic for small to medium-sized buildings. The range also allows an existing system to be extended or modified if necessary. This flexibility makes AlarmSense an excellent choice for use in HMOs House in Multiple Occupation.As you would expect from Apollo AlarmSense incorporates features that help reduce false alarms and patented technology to ensure the integrity of a system. The range also includes products such as beacons to help meet the requirements of the Disability Discrimination Act DDA.Brand FeaturesAlarmSense sounders and manual call points are fitted to the same zone as detectors. In quiescent state the zone is powered at between 9V and 15V nominally 12V at which only detectors and call points operate. Sounders require 24V to operate.When an alarm is detected on a zone the control panel increases the line voltage to 24V on that zone causing the sounders to produce a continuous Evacuate sound. Any voltage-sensitive output devices - relay modules or other alarm devices - also operate.When the voltage is increased to 24V the detector alarm current will reduce to 1.5mA. The detectors are latched in alarm until they are reset by reducing the voltage to less than 2V for greater than 1 second. Output devices will de-activate each time the voltage is reduced to 12V unless otherwise stated in their specification.It is possible to generate an Alert tone by pulsing the supply voltage from 12V to 24V and the sounders configured to continuous output. Pulse frequency of 1 second on 1 second off is recommended for compliance with BS5839 Pt1.Key Features Sound output of up to 99dBLPCB approvedSeparate first-fix base for ease of installationIP65 rated outdoor useDesigned for use as part of an AlarmSense fire alarm panel systemWall mountedTone synchronisationMonitors the presence of the sounder head
