E-Mag & E-Mag2 (Electromagnetic Valve Release Mechanism)
(SQR MK1 & SQR MK2 Type Devices)
E-Mag’s provide instant release of Free Fall Fire Valves when de-energised, they have a 2kVA power rating, 40Kg electromagnetic holding power as standard and a ‘push to test’ facility, making them ideal for remote fire valve closure.
Available in the following options –
20-162 E-Mag 24V DC
20-163 E-Mag 110V AC
20-164 E-Mag 240V AC
20-165 E-Mag2 24V DC, with n/o and n/c contacts
20-166 E-Mag2 110V AC, with n/o and n/c contacts
20-167 E-Mag2 240V AC, with n/o and n/c contacts
See our 20-183, 24V DC Battery Backed Fire Valve control panels to support our 24V DC E-Mag range in case of mains failure.
E-mag & E-mag2 technical details can be viewed within our Free Fall Fire Valve brochure.
20-160 MQR (Manual Quick Release)
Designed for use with ‘fusible link operated free fall fire valve’ systems
Provides manual release of fire valve systems
Can be used in conjunction with E-Mag & E-Mag2
20-161 EMQR (Electro-Manual Quick Release)
EMQR‘s are available with 2 sets of volt free contacts and optional Red/Green LED indicators.
230V ac operation
24V dc operation
Wiring diagrams are available within our Free Fall Fire Valve brochure.
Fire Valve Control Panels
FEL Fire Valve Control Panels are used to maintain power to an E-Mag or SQR type device.
Power output options are 230V AC or 24V DC, with 230V AC input
24V DC Units are battery backed and designed to maintain power output in the event of mains failure whilst continuing to provide fire detection through electro-thermal links or normally closed emergency push buttons wired in series
Battery backup time and battery size is calculated on the required load to maintain multiple E-Mag, Motorised Valves or SQR type devices
BMS connectivity via volt free contacts
Panels available:
230V AC Input/ Output Fire Valve Control Panel 20-180
230V AC input / 24V DC Output Fire Valve Control Panel 20-183
