Fig. 2 Emergency Release
3.4 EMERGENCY RELEASE TERMINALS
The LED illuminates when the power module or batteries are operating. +V is terminated
at terminal F1, a connection is then made between terminals F1 and F2 before +V
is routed to the “P” terminals (Fig. 2 and 3). Terminals F1 and F2 constitute an
emergency release point. Note: An NC contact, controlled by the user’s fire alarm
system, can be connected across terminals F1 and F2 so the connection between
these terminals will be broken in the event of a fire. UL listed auxiliary latching
normally closed contacts from the fire alarm system should be used. “Trouble”
contacts* must not be used. This will automatically release all the power to devices
being driven by the unit. If the emergency release terminals are not to be used in this
way, a jumper should be placed between F1 and F2, so the board’s output terminals
will function. Ensure that the switching capability of any switch or relay contacts
placed across F1 and F2 can handle the full output load of the power supply.

Notes:
1) “Min” time refers to facilities using an emergency generator where the batteries are only required to operate the system for under 3 minutes until the generator
takes over. Ah refers to ampere hour.
2) UL Standard require 4 hours of battery operation followed by a 24 hour recharge period and then a second four hours of operation.
3) Standard Sargent power supplies can only charge up to a 20 Ah pack.
If a larger pack is called for, the factory must be alerted to supply modified equipment. Larger packs are shown in italics in the chart.
3) Batteries must be sealed lead acid or gel cell type. Dry cells will not recharge and will be damaged.
4) The chart above is valid when batteries are operating at room temperature; in a cold environments, capacity is reduced.
5) Batteries should be replaced after 5 years of use.
3.3 BATTERY CHARGING CAPABILITY
The power supply incorporates a battery charging circuit appropriate for standby rated sealed lead acid or gel cell batteries.
Battery backup is available by ordering a 737-12 Volt or 738-24 Volt Battery Backup Kit.
A resistor and diode are present on CCS boards which, together with the power supply, constitute a battery charging circuit
appropriate for standby rated sealed lead acid or gel cell batteries. Dry cell or NICAD batteries must not be used. Batteries are
an option. The power supply can be used with or without them.
IMPORTANT: The battery pack of the appropriate voltage is connected to the red and black flying leads following correct
polarity.
In the event of an AC power failure, the batteries will automatically provide current to output loads. However, if the emergency
release terminals F1 and F2 are opened (Fig. 2), battery power will be blocked.
The components utilized on the CCS board for battery charging function for battery packs up to 20 amp hours in capacity
with either 12 or 24 volts. Larger battery packs can be accommodated (Table 2). Calculate the correct battery pack based on
desired backup time and the current draw by the load (Table 2). For proper battery charging, the power supply must be set at
13.5 volts for a 12 for volt system and 27 volts for a 24 volt system. SARGENT power supplies are factory set at 12 volts or 24
volts respectively and must be adjusted or batteries will not hold their full capacity and could be damaged.
