PS17-TD2
Access Control Power Supply/Charger
Rev. 062101
Overview:
The PS17-TD2 is a power supply that will convert 115 VAC/60Hz input into two individually PTC protected
12VDC or 24VDC outputs (see specifications) and provide time delays to conform with both Delayed Egress and
Access-controlled Egress provisions of the U.S. model building codes. It is intended for use in applications
requiring UL Listing for Access Controls (UL294) and applications requiring an interface with Fire Alarm
Control Panels. It must be installed in accordance with National and Local Electrical Codes and Regulations.
Specifications:

UL Listed for Access Control System (UL294).
Switch selectable 12VDC or 24VDC power limited output.
Input 115VAC/60Hz, 0.6 amp.
1.75 AMPS continuous supply current @ 12VDC or 24VDC.
Filtered and electronically regulated output.
Outputs are overload protected by PTC’s.
Delay timing is reset (before, during, or after a delay) by
dry contact closure (RES & GND).
• An output is provided for unlocking devices (electric strikes).
• An auxiliary output is provided which is not affected by the
Fire Alarm Relay Terminals.
• An AC Fail relay (Form “C” 1 A @ 28VDC) indicates AC is powering unit.
• A green LED also indicates the AC is powering unit.
• A red LED indicates the DC outputs are powered.
• An output relay (Form “C” 1 A @ 28VDC) indicates the DC Lock+ terminal is powered
and not the Strike+ terminal, or vice versa.
• Field selectable: Delayed Egress, Access-controlled Egress, or no delays (a standard power supply).
• Delay for delayed egress applications is 15 or 30 seconds field selectable.
(Except factory shipped “UBCDE” model.)
• Delayed egress has field selectable none or 1 second nuisance delay.
• Delayed egress has alarm relay to switch on alarm power.
• Delay for access-controlled applications is 30 or 45 seconds field selectable.
• Delays are triggered by a dry contact closure (TR & GND).

Battery Backup:
12VDC - One (1) 12VDC 7.2Ah battery will provide 4 hours of backup @ 1.25 AMPS.
24VDC - Two (2) 12VDC 7.2Ah batteries will provide 4 hours of backup @ 1.25 AMPS.
Note: For Access Control applications, batteries are optional. When batteries are not used a loss of AC will result in the loss
of output voltage. When standby batteries are used, they must be lead-acid or gel type.
Installation Instructions:
The PS17-TD2 should be installed in accordance with The National Electrical Code and all applicable Local
Regulations. See Terminal Identification Chart on page 3 for a description of each terminal function.
1. Mount the PS17-TD2 in desired location.
2. Connect 115VAC to the black and white flying leads of the transformer.

9. For monitoring the output relay governing terminals marked [Lock+ and Strike+] use the [C, N.C. and N.O.]
terminals next to [TRG1 and TRG2]. C will be closed to N.C. when Lock+ is powered.
10. When a Delayed Egress is used, an alarm is required by all Codes. The alarm relay is used to switch on the
alarm. C will close to N.C. when the alarm should sound: immediately at triggering with no nuisance delay, or
after one continuous second of trigger with nuisance delay. If moderate power is required for the alarm it can
be obtained by jumping [AUX+ to C] on the Alarm relay; and N.C. on the Alarm relay and [AUX ---] to the alarm.

Terminal Identification:
Terminal
Legend
Function/Description
TRG1 & TRG2
These input terminals are designed to connect to the closed C and N.O. terminals of
an access control or fire alarm relay. These must be jumped otherwise. These
terminals control LOCK+, and STRIKE+, as well as PS17-TD2 output relay contacts
N.C., N.O., C.
LOCK+
This terminal provides DC output voltage when TRG1 and TRG2 are shorted together
and are typically used to power electromagnetic locks. Two locks may be connected
in parallel on LOCK + and COM --- (Fig. 2, page 5).
STRIKE+
This terminal provides DC output voltage when TRG1 and TRG2 are unshorted and
is typically used to power Electric Strikes.
N.C., N.O., C
(adjoining) TRG1
& TRG2
Isolated dry Form “C” contacts. Shorting TRG1 and TRG2
together causes these contacts to switch. They are typically used
for controlling multiple power supplies with fire alarm tie-in (Figs. 7 and 8, page 7).
AUX+
Continuous positive (+) DC power output voltage. It is not affected by
TRG1, TRG2 operation.
COM --- , AUX ---,
BAT ---, GND
(adjoining RES),
GND (adjoining TR),

FACP

BAT+, BAT-
Battery backup connections. Apply proper voltage SLA batteries.
Batteries are trickle charged with 13.6 or 26.6 volts.
RES & GND
Are normally open. To reset either time delay at any time-close momentarily.
TR & GND
Trigger either Delayed Egress or Access-controlled Egress by closing momentarily
TR to GND. If nuisance delay is on in Delayed Egress Mode, trigger must be closed
continuously for one full second.
