Power Supply Output Specifications:
Output VDC Switch Position Max Load DC
12VDC SWI ON 1.75A
24VDC SWI OFF 1.75A
Stand-by Specifications:
Output 4 hr. of Stand-by & 5 Minutes of Alarm
12VDC / 7 AH Battery
Stand-by = 1.25A
Alarm = 1.25A
24VDC / 7 AH Battery
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.
LED Diagnostics:
Red (DC) Green (AC) Power Supply Status
ON ON Normal output, powered by AC.
ON OFF Battery backup is powering output.
OFF ON No DC output.
OFF OFF Loss of AC. Discharged or missing stand-by battery. No DC output.
Battery Back-up: Use sealed lead-acid 12 volt secondary lead-acid only. Connect two in series for 24 volts.
When using standby batteries house them in a separate enclosure.
Terminal Identification:
Terminal Legend Function/Description
TRG1 & TRG2
These input terminals are designed to connect to the closed C and NO 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 NC, NO, 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, pg. 4).
STRIKE+
This terminal provides DC output voltage when TRG1 and TRG2 are unshorted and are typically used to
power Electric Strikes.
NC, NO, C (adjoining)
TRG1 & TRG2
Isolated dry Form “C” contacts. Shortening TRG1 and TRG2 together causes these contacts to switch. They
are typically used for controlling multiple power supplies with fire alarm tie-in (fig. 4 and 5, pg. 7).
AUX+ Continuous positive (+) DC power output voltage. It is not affected by TRG1, TRG2 operation.
COM –, AUX –,
BAT –, GND
(adjoining RST)
GND (adjoining TR)
Are all common (–) output (ground)
FACP Spare wiring terminal used for fire alarm tie-in application (fig. 3, pg. 5)
BAT +, BAT –
Battery back-up 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-closed momentarily.
TRG &
GND
Trigger either Delayed Egress or Access-controlled Egress by closing momentarily TR to G.
If nuisance delay is on in Delayed Egress Mode, trigger must be closed continuously for one full second.
Equipment and systems intended to be operated with a sensor release feature shall be constructed to operate so that when the sensor
detects an occupant within 5 feet of the egress side of the door, the door locking mechanism will unlock the door.
