PS17-TD2
- 1 -
Overview:
PS17-TD2 is a power supply that converts 115VAC, 60Hz input into two individually PTC protected 12VDC or 24VDC outputs (see specifi-
cations) and provides 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:
Requirements For Delayed Egress:
An audible alarm shall be provided that shall activate upon initiation of the delayed timing process and continue signaling until the
door lock is released. Follow wiring diagram on pg. 3 for hookup. Please make sure the operating voltage of the sounding device matches
the preset outout of power supply. Use 12V devices for 12V setting and 24V devices for 24V setting.
Special locking device interconnected with the power supply shall be plainly marked on the hardware assembly: “Controlled Egress
Equipment and Systems”or “Delayed Egress Equipment and Systems”.
For delayed egress locking devices, the programmed time delay duration shall be plainly marked on the hardware assembly.
Requirements For Controlled Egress:
Activation of a fire alarm signal or fire sprinkler signal shall release the door latching mechanism to allow egress in a time frame
not to exceed two seconds. The door shall remain unlocked until the fire alarm control unit has been reset.
Connect [TRIG1] and [TRIG2] terminals to Normally closed Fire alarm contact (fig. 3, pg. 5).
Special locking device interconnected with the power supply shall be plainly marked on the hardware assembly: “Controlled Egress
Equipment and Systems”or “Delayed Egress Equipment and Systems”.
Equipment and systems shall be provided with a means to release door latches upon activation of a manual release switch intended to be
installed within 5 feet of the door. Activation of this manual release switch shall cause the door to remain unlocked for 30 seconds Activate
TRG and GND Input by means of NO dry contact. Follow wiring diagrams and DIP switch settings for proper hookup.
Equipment and systems utilizing an electromagnetic locking mechanism shall be capable of being operated with one hand.
The releasing mechanism shall interrupt the power to the electromagnetic lock to unlock the door.
Requirements For Fire Exit and Panic Applications:
Equipment and systems designed as fire exit or panic hardware shall comply with the Standard for Panic Hardware, UL 305.
Interruption of power shall cause the locking mechanism to unlock/release in less than 2 seconds. Do not use battery backup.
Activation of a fire alarm signal or fire sprinkler signal shall release the door latching mechanism to allow egress in a time frame not to
exceed two seconds. The door shall remain unlocked until the fire alarm control unit has been reset. Connect [TRIG1] and [TRIG2] termi-
nals to Normally closed Fire alarm contact (fig. 3, pg. 5).
A means to release door latches upon activation of a manual release switch shall occur within two seconds following initiation of TRG and
GND Input by means of NO dry contact. Follow wiring diagrams and DIP switch settings for proper hookup.

Fire Alarm Relay Terminals
(1.25A @ 12VDC/24VDC for UL Installations).
Supervision:
• AC Fail relay (Form “C” 1A @ 28VDC) indicates
AC is powering unit.
• Output relay (Form “C” 1A @ 28VDC) indicates the [DC Lock+]
terminal is powered and not the [] terminal, or vice versa.
LED Indicators:
• A green LED also indicates the AC is powering unit.
• A red LED indicates the DC outputs are powered.
Delayed Egress:
• Field selectable: Delayed egress, Access-controlled egress or
No delays (a standard power supply).
• Delay for delayed egress applications is 15 or 30 sec
field selectable.
• Delayed egress has field selectable none or 1 sec nuisance delay.
• Delayed egress has alarm relay to switch on alarm power.
• Delay for access-controlled applications is 30 or 45 sec
field selectable.
• Delays are triggered by a dry contact closure (TR & G).
• Delay timing is reset (before, during, or after a delay) by
removal a dry contact closure (RES & G).
