ZIC-4A Releasing Service Wiring With PSC-12 Power Supply
NOTES
1. All wiring must be in accordance
with Article 760 of NEC or local
building codes.
2. All output circuits are power
limited to NFPA 70 per NEC 760.
3. Electrical Ratings: 24 VDC
2mA max @ Supervisory
3A max @ Alarm
4. Maximum line resistance: Refer
to table on pages 12 or 16.
5. Use only Pre-Action/Deluge
solenoids listed in tables on page
14.
6. For FM Approved Pre-Action/
Deluge: All initiating devices
conntected to the system must
be wired CLASS A.
7. Refer to Figure 9 for ZIC-4A
output soldenoid wiring for
Releasing Service. Connect the
zone ouput appropriately.
8. Inputs can be daisy-chained
provided that the power supply
can sustain the power require-
ment of the output when
activated.
9. Refer to Zeus Quick Start Guide
(P/N 315-033875) for information
about programming of releasing
service.
10. Refer to CAB1/CAB1R (P/N 315-
0330007) and CAB2-BB/CAB3-BB
(P/N 315-033009) Installation
Instructions for details on the
separation of power limited and
non-power limited wiring.
11. 90 hour standby power is required
to meet FM Approved installation
requirements. Refer to PSC-12
Installation Instructions, P/N 315-
033060 for battery calculations.
FOR FM APPROVED INSTALLATION ONLY:
Double Interlock
A sprinkler system comprised of two interlocks - an interlock which opens when
Pre-action Systems
powered by a listed releasing panel and a second interlock which opens when a
pressure loss is experienced in the sprinkler pipes between the interlock and the
system’s sprinkler heads.
Both interlocks must be open at the same time to allow for the flow of water to initiate.
A specific sequence of operation is required with all Siemens panels with listed
releasing capabilities.
The FireFinder-XLS/Desigo Fire Safety Modular/Cerberus PRO Modular panel will
indicate an alarm if one detector detects an alarm condition. The system will not
energize the releasing circuit until an additional detector detects an alarm (any two
detectors in the same protection zone covering the sprinkler system) AND the panel
receives a low pressure indication from a pressure switch placed in the sprinkler
piping between the second interlock and that pipe system’s sprinkler heads (indi-
cates that the second interlock is in OPEN position). If this sequence is not followed
precisely, the correlating system design may not properly activate the double inter-
lock preaction sprinkler system, therefore, preventing the water from discharging
during a true fire incident.
