Power and Cable Requirements:
Power Requirements
•
Each 4 zone keypad’s current draw is 110 mA. Multiple modules cannot be powered direct from the module bus. A
local power supply must be used.
•
Power supplies must be located very locally to their 4 zone keypads.
•
All power supply negatives must be common and connected to the ISM panel module bus negative.
•
Power supply wiring has to be of a gauge large enough to provide correct voltage at the last module in a run, belonging
to that power supply. Typically 18 gauge or larger. 18 gauge power cable: Guardall P/N 947-3400.
•
In a multiple floor, riser installation with a height of 10 feet (3.1 meters)/floor, using 18 gauge power cable with a lead in
of up to 100 feet (30.5 meters) from power supply to the first module, the power supply will be limited to powering
seven modules, only. This will ensure 12V at the last module of the group. The next group of 7 modules up in a vertical
formation, would then need their own power supply, located within 100 feet (30.5 meters) of that next group’s first
module.
•
Seven modules will require a minimum 1 AMP power supply. A larger capacity power supply can be used, however, it
is still limited to seven modules, due to the power loss in the cable.
•
A 4 zone keypad requires 12 to 13.8 volts DC to function normally. However, under extreme conditions (e.g. primary
power loss) it can still process activities marginally at 10VDC.
•
The module communication cable must not carry the power supply current because of the smaller wire gauge.
•
Both wires in the power cable must be of the same gauge (e.g. 18AWG).
•
However, the spare wire pair of the communication cable can be used to common the negatives of the various power
supplies with each other and the ISM module bus 0V negative, which, is required.
Cable Requirements for Module Bus Data A and B
•
24AWG, 2 twisted stranded pair, shielded, with an impedance value of 120 ohm, low capacitance: 12.5-pF/1 foot (41-
pF/1 meter), e.g. Belden 9842. Guardall P/N 947-3401 communication cable meets these specifications.
•
The communication cable shield is grounded at the ISM main panel end (e.g. panel ground lug). “B” connected
together at each module interconnection and cut off, not connected to anything, at the last module in the group.
•
The maximum module cable distance is 2000 ft (610 meters) per ISM main panel module bus 1 or 2 at the main control
unit motherboard. Module star wiring configurations cannot be used. Module connections must run on a straight trunk,
with no straight out, branch offs to another module. You must go out to the module and come back with the cable to go
to the next module.
•
For ISM main panel module Bus 1 and 2 should be evenly balanced with up to 30 Suite Security keypads each to equal
the system capacity of 60.
•
If more than 30 modules are required to be on a single bus, a SNAPP Expander module should be placed in series with
the SNAPP bus to split the modules into approximately two equal groups along the length of the SNAPP bus. The
SNAPP Expander module should be located near a power supply to provide power to the expander as well as the 4
zone modules.
Special Installation and Servicing 4 Zone Keypad Command Features:
Display a 4 Zone Keypad’s 5-Digit Programming Serial Number:
Prevents the need to remove the keypad housing from its base to review the Suite Security programming serial number
label on the back of the keypad’s printed circuit board.
1. Number is displayed for 4 seconds after the 7 second power up delay.
2.
If unit is already powered then
•
enter a valid ‘PIN’,
•
select “Status”
•
select
“Other”
•
Display will show the F/W version and unit serial number.
