1.2 Specifications
AC Power
6.5A POWER SUPPLY AC Input max 3.2A (120VAC) 1.6A (220VAC) model number S-150-24.
Battery (sealed lead acid only)
Maximum charging circuit
– 0.98A&22VDC
Maximum charger capacity: 18 amp hour battery (two 7 amp hour batteries can be housed in the
enclosure. Larger batteries require a separate Battery Cabinet MBC “Mini Battery Cabinet”
manufactured by space age.
SLC Circuits
The MA-1000 Panel comes with two SLCs loops (optional 4 SLC loop card) which has the following
parameters:
Supply voltage: 24 VDC nominal, 27.6 VDC maximum.
Addressable Loops
Max Number: 2
Max Load per loop: 60 mA
Maximum loop current is 150 mA (short circuit)
Max Number of Addressable Devices per loop: 200
The total number of addresses per loop is 200; this includes detectors, manual pulls and all other
addressable items
. When designing systems it’s recommended that allowances are made for future
expansion, Short circuit isolators are incorporated into every MA-1000 loop device, including Smoke
detectors, heat detectors, sounders, manual pulls and interfaces. Therefore, no further fault
protection is required, in the event of a single fault; none of the devices connected to the loop will fail
to operate as the fault will be isolated by the two adjacent devices.
T-tap connected devices downstream of a cable fault will cease to function.
